At present, the principal 3razil monazite deposits consist of modern Aro
recent marine beaches along the Atlantic coast in the states of Rio de Janiero;
Espirito Santo, and 3ahia. These beach deposits vary both in the content d.
the composition of their heavy sands. The heavy mineral concentrates cons int
predominantly of ilmenites monasite, and zircon. In addition to beach san
nearly all of the rocks and clay derived therefrom contain monazite. It, i3

along much of the Atlantic coast bordered by the states of Rio de Janiero,
Espirito Santo, and Bahia. As a matter of fact, panning tests of clays
derived from the country rock in many parts of Espirito Santo showed
appreciable amounts of monazite.
The Brazil beach deposits are oftwo types, recent and modern, represented
schematically in Figures 1 and 2.
FOMIL monazite deposits are in Espirito Santo and are named as follows

In addition MIL has first rights to mineItapotanga, when such
rights are granted by the DNPM. FOMIL is also considering the prqchase of
the U b ix mine which, is awned by a farmer at Ubu, E. E. Santo.
The Torres properties were leased to FOMIL for a three year period
beginning Jan. 1, 1947 on a royalty basis of Cr$600 per metric ton refined
monazite produced. The du Pont properties are now in FOMIL's name and ere
obtained from du Pont when the latter ceased ilmenite prospecting in Dra '1.
FOMIL has pronpected all of their properties. Their prospecting method
consisted of taking samples with a pat hole digger until clay or eater NTS
reached (up to 6 meters deep). The overburden sample was discarded, and a
representative sample of the concentrate sand layer (if present) was made by
quartering. Concentrate sand lenses were thus outlined and the depths noted.
Sampling was usually done every 30 meters. The samples were taken to the
Vitoria office, and after washing, grain counts were made. We consider the
sample taking method as being adequate, but we do not believe that the grain-
count azi*PoivsedtgotMelielMANOIE :ta-0151gOlebirk0618

CA PUBA
This is a recent beach deposit about 2 km. lonc situated about 30 km..
NNE of Vitoria and about 300?500 meters from the present beach. Du Pont
formerly considered working the area for ilmenite. We did not see much ci
this property; no good mining areas were visited.
FOMIL is doing no mining at Capubal but intends to mine it for sir )r

Du Pont reported the average composition of the sand in the mine is

and estimated the mine to contain 11,500 letric tons of ilmenite. 3ased on
this, the mine contains 680 metric tons of monazite. However, graft says that
the du Pont prospecting did not take into account the generally accepted rule
.in such deposits that monazite tends to concentrate in the deeper Irarts of the
deposits; the du Pent prospecting was shallow, and test holes were not made to
clay or water. We have heard that du Pont now admits that their d ati
on the
monazite contents of their Brazil prospects are too low.

These mines are located about 20 km. NE of Vitoria and are of the rccnt
type. The mines total about 4 km. in length and the mineable areas weru re-
ported to be up to 30 meters Ade. The heavy sands consist of limonite, zircon
and noziazite,

? Du Pont estimated that a 10 cm. thick layer of imncentrate contained on
the property would contain 401480 metric tons of ilmenite. On this basis, the
same layer would contain 1,850 tons of monazite. POMIL's test holes showed
rich lens of sand on Carapebus No. 1 which was missed in the du Pont prospect
Only a small portion of one ore body on Carapebus No. I was visited. Three
ore bodies on Carapebus No. 2were confirmed with the Geiger meter. Neter read-
ings of 0,05-0.15 mrihr. were observed (background 0.02 mrihr.). at points
indicated by Kraft to contain lenses of. heavy sands. Confirmations of ore
bodies disclosed by FOMIL was satisfactory with the Geiger meter provided the
ore layers were not too deeply buried. The three ore bodies on Carapebus No. I
were reported to have average thicknesses of one meter, widths piot1ng
10 m?ters, and lengths of about 300 meters. Panning tests of mined concentrat
showed about 50% heavy sands and 2,5% monazite (about 5% monazite in th heavy
mineral concentrate).
Panning tests of "barren" sande showed about 0,5% monazite.
Considerations of du Pont's surveys indicate that Carapebus No. uay
contain 2,000-3,000 tone monazite. Including the "barren" sands, it
estimated by us that the mine contains at least 25,(O0 tons monazite.
FOMIL's surveys indicate five ore bodies, and Kraft estimates t
five deposits contain 2,500 to 3,000 tons of monazite not considering
barren sands.

At the north end of Bsperito Santo Bay,we saw a small beach of modern
type (Fig. 2) which consisted of black sand containing about 5,10% momeite,
Clay from the cliffs near by showed approximately 0.1-0.5% monazite on panning.
Part of Carapebus No. 2 was worked about 20 years ago by the French. Two
stockpiles of unwashed beach ooncentratesvere left on the property. Geier
meter readings on the two piles were 0,1 to 0.15 mr/hr., and panning tostf showed
that the material in the piles contained about 50% heavy sands and 2.5% mnazite
(or 5% monazite in the heavy mineral concentrate). The two piles were estimated
to contain about 500 to 1,000 tons of heavy minerals.
PONTA DA FRUTA
The Ponta da Fruta mines Nos. 1 and 2 are located near the vi1iae of
Ponta da Fruta, about 35 km. S'of Vitoria and about 20 km. NE of Quarapari.
The deposit is of the recent type. The No. 1 mine is 4 km. long and
the adjacent No.2 mine is 2 km. long. The thickness of the natural concentrate
layer vAe reported by FORM tote 1-3 meters and About 20-30 meters wide.
Du Pont's estimation of the average composition of the sand at Ponta da
Fruta No. I was as follows:

They estimated that the ne contained 61,000 metric tons of limonite;
on this basis it should contain 1,500 metric tons of monazite. More monazite
than this is present because the du Pont surveys did not include the lower
natural concentrate layer where the monazite content of the heavy mineral snnd
iszre er.
FOMIL had not completed calculations of their prospecting test holes at the
time of our visit. Geiger meter prospects by us shoved that the mine contained
eonsiderable monazite.

&MIL started Tining at Ponta da Fruta 1 in 1948, intending to ship a
sircon-ilmenite mixture to the Foote Mineral Co. of Philadelphia. However,
when mining was started it was found that the amount of monazite in the ricen-
trate was so high that shipment of the concentrate was impossible. ining was
done by washing off approltimately 3 ft. of overburden sand with a ira.i11.c run,
and then the underlying 6.10 ft. of natural concentrate layer was pumped with
water over six roughertables and four cleaner tables. The table tai] tags were
pumped to the beach. The heavy mineral concentrate thus produced was tote loaded
onto a barge at the beach (100 ton capacity) and was to be shipped to Vitoria.
Mining operations were suspended pending the installation of separation evti?iiient
at Vitoria. Production from the tables averaged 0.5 ton heavy minerals per hour
pert able for six tables. Only a small stock of concentrate was made and this is
at the mine.
A sample of the heavy mineral concentrate produced by the tables had the
following analysis (AN 485129):
Ilmenite - 46.0%
Monazite -------------- 13.4
Nonmagnetic - 40.6 (largely zircon
7:15n
Assuming that the mined sands contained 50% heavy minerals of the above
composition, the mine aould contain 110,000 tons heavy mineral concentrate or
50,600 tons ilmenite, 14,700 tons monazite and approximately 45,000 tons ziron,
exclusive of these minerals contained in the overburden and "barren" 3T.:-.nea;.

The Mai-Ba mine is a modern beach deposit located on the present ocaf n
beach adjacent to Lake Mat-Ba about 10 kr, from Anchieta. It is about 2,000
meters long and the mineable area is about 10.15 rioters wide adjacent to k brut
lay cliffs which are about 20 to 30 meters high.
This is the only FOMIL beach mine being worked. Operations were startet
on May 13. 194$._

Mining is done by r emoving approximately 10 ft. of overburden sand near the
cliff base. The thusly exposed layers of monazite and black sand are shoveled
out selectively. The monazite bearing veins vary from 1 cm. to 1 meter thick
the average of those seen was about 10 mt.; and the total vein thickness reacved
is about 0,5-1 meter. The natural concentrate they removed is supposed tots
roughly adjusted At the mine to contain about 20% heavy Minerals. It is trans-
ported by truck to the mill located about 100 meters front the mine. After
storms, considerable monazite concentrates are found on the beach, and these
are scraped up and t emporarily stored in piles on the beach for transportation
to the mill.
The monazite-rich veins exposed in the mines often consist locally of 70-
monazite, and occasionally, cemented monazite sandstones are found adjacent
to the cliff.
At the mill, a reserve stock of about 4,000 tons of mined sand is kert on
hand for t abling in case of inclement conditions on the b each which prevent
raining. This stockpile was sarnpled and analyzed as follows (AN 4,85126):

The mined sand- at this mill is shoveled into a launder and the sand slurry flows
by gravity onto t wo Deister tables having 4 ft. X 1.0 ft. decks. The tables aere
somewhat overloaded and a concentrate containing about 55-702; monazite was
produced at the rate of approximately 1-1.5 ton per hour pe r t able. The mama-
cite recovery was estimated to be about &V.
Tailings from the tables flow by gravity to a pump where they are presently
pumped to a pile located between the mill and beach. FOMIL eventually contemplates
pumping the tailings directly to the beach, a distance of about 100 meters, whea
pipe can be secured.

Analysis of a sample of tailings taken Aug. 18,1948 showed (AN 4851
28.7% lime:lite
3.5% monazite
67.8% nonmagnetic sands
Monazite concentrate from the tables flows into boxes (2 mt. meter cap*ca
where the excess water is drained off. From these boxes, the concentrate is
shoveled to a temporary stockpile which is trucked to a warehouse on the wharf
at Anchieta. There it is bagged for barge transportation to the ma7tetic separa-
tion plant at Vitoria.
Production of tabled monazite concentrate averages 1.0-1.5 ton per hour per
table. For a 20 hour day, 26 day month, the production from two tables could
therefore be over 1,000 tons of concentrate per month. The actual average produc-

From panning teats we estimated that the "barren" sand on the beach surface
contained about 2% heavy minerals and 0.05-0.1% monazite. The entire mine may
contain 20,000-30,000 tons of monazite in the high grade veins now beir.k; mined
and it may contain an equal amount in the overburden "barren" sands. Kraft
believes that any estimate of the amount of monazite in the mine is impo '
because he reports that mined-out holes canbe re-worked after storms;

in fact he reported that one bole has been mined four times to date.
It is our opinion that additional tables should be installed at the nill to
give greater monazite recoveries. FIDMIL plans to install a third table to wash
he tailings from the present bo tables to recover additional monazite and. ar
ilmenite fraction which will ie stockpiled at the mine and returned. to Torres

From: Howard E. Kremers 3eptemLer 5,
Subject; IfEMCO-HOrE MAGNETIC bEPARATO% AT THE FOMIL "n" PLANT.
Following is. a summary of my observations and opinions on the performance of
the Fomil magnetic separator. Alltests were made in the presence of either J. rawford
or Ed Kraft. Mai-Ba concentrates containing about 60 to 72% monazite were used.
When first seen, the machine was adjusted by the M personnel and was giving an
iImenite-garnet mixture on the first three poles, and a clean monazite on the las
three poles. The maChine. was operating at maximum amperage at 230 volts, was
producing .cleaned monazite at the rate of approx. 25 Kg. per hour (005 ton y,er day).
Slight adjustments to decrease the air gaps between the main and cross belts gave a
slightly better yield. With the air gaps as small as possible (less than 1/8 inch)
time tests at varying amperages indicated that the last three poles were operating
very close to maximum magnetic flux.
After various adjustments had been made we were able to increase the yield of
monazite to approx. 100 Ke. per hour. The following data were t aken after a. two-
hour "warm rup" period;
Feed rate: 424 Kg,/hr, (maximum possible)
Belt speed: approx. 50-60 ftimin. (slowestpossible;
increase in belt speed gave poorer results)
Air gap:. less than 1/8 in. (as all as possible)

At high feed rates, the monazite fractions were badly contaminated with thir

be not successful. The only c,rrection is to retap the first pole tIci re-
locate the brass shoes. With such correction, the caoacity undoubteely cem be in-
creased.
The sand plltters on the cross belts are poorly designed. It it iajosible
to male satisfactory adjustments with the present equipment. The sard r-.3eeivers
should be modified so that control can be made by adjusting vanes to split the
monazite and ilmenite sano streams.
Repassing the nonmagnetic tailings which contain approx. 3o-.60 :nn .aite aoes
not give a satisfactory recovery of clear monazite. Apparently the J-7-!gh,4s are
strong enough to pick up the 3pre weakly magnetic monazite sands.
It has been consistently observed that a slightly better separation as obtained

not stretched too tight, the joint in the belt began to loosen resulting in a
troublesome bow in the middle of the belt. Before farther operation, theelt will
have to be repaired. The belt joint should be vlacanized.
It is possible to completely remove il

All of the suggestions offered by Foote in thier cables of the past week have
been tried. With appropriate alterations of the machine, it be possible, to
produce 75 K. cleaned monazite per hour (450 metric tons per year at 20 hours )er
day and 300 day year operations).
In my opinion, the separator is poorly designed in the following ways:
1. The magnets are too weak.
2. The first pole is out of alignment.
3. Th, cross belts are too thick.
4.. The main belt is not vulcanized and is slightly irreuler.
5. The sand splitters on the cross belt receivers are poorl:,, ,ye*7ned,

Cost estimates:
The diesel generator and crier each consume about 15 liters of oil pe r hour.
The oil costs Fomil C$1.35 per liter. For 20 hour day operation, the, oil (c)sA, is
approx. US$40.00. Labor costs at the 113 plant are approx. US$15.00 per ;i y. For
a daily 20 hour operation with a recovery of 100 K. cleaned monazite per (2
metric tons per day), the separation cost would be about US$27.50, exclulNu of
overhead, maintenance, mining costs, etc.

Since the removal of Limonite alone could be easily done with the separator,
it was thought that screening this material through a 60 mesh screen ihoule give
a +60 mesh material which might be acceptable monazite, or could be blended with
refined monazite to give an acceptable monazite! If practical, such a tvcedure
might increase the ?OMIT, output of refined monazite. An experintal mile of
ilmenite-free tailings produced by the separator and containing (AN 485l2F!) 2.1%
ilmenite, 72.5% monazite, and 24.4% nonmegnetic sands was screened or a 60 mesh

monazite. On Sept. 27, 1948 we received from Kraft a sample of MM-Ha material
from which the ilmenite had been removed on the MIL separator and which was
screened at the MS plant; it analysed (AN 485156) B14 monazite, 44 iltenite and
15% zircon.

In order to fortify this to 95% monczite, one part of the a5z
would have to be blended with two parts of 100% monazite. In order
the 85% material to 90% monazite, Iwo parts of the 03% material would

order to produce onazite, the capacity would be based on the otenti.,.1
monazite production, and the total yearly production of 90% monazite would 1-)e
approximately 1,300 tone. Improvements in the design and operation of the

The low grade material is discarded. In all of the beach mines, the

which is oonsideree worked-out, could be profitably worked to recover
additional monazite.
(2), Sore mines, such Mai-Ba? are continually depositing mortazite.

(3). No surveys have been made of the monazite resources of beach sands
