Lead is rarely found as an independent ore, but usually occurs together
with zinc, copper, and other petals, to fags a polymetallic c..e. USSR reserves
of lead, are are larger than those of any capitalist country. In Lha i388R, poly-
metallic ores are t,? 'se found in the following areas:
2. Nerohinsk Rayon (Eastern Transbayeal), large Kttdainsk deposit

1. Far Eastern Deposits
4. Altay. (Kazakhstan), large Leninogorsk and Zyryanovok de~atitts
The Far Eastern deposits of polymetallic ores are located on the shore
of the Bea of Japan, on the eastern slope of the Sikhote Alin' mountain range.
The largest of, these is the Tetyukhe deposit.
The form and condition of the occurrence of the ore body are extremely
diverse. There are ore seams at the contact of limestone and quartz porphyry;
stratified seams and veins at the Junction of limestoneo'and tuff with argil-
laeeous shale; stratified cross veins in argillaceons shale; and.. finally, the
zone of phanocryst And strata of fine irregular streaks in quartzites1 and
siliceous shale.

Pyritic ores consist of galerlto,, z'no blends, copper pyrite, magnetic
pyrite, pyrite, white iron pyrite, arsonopyrite, small amounts of gray copper
ore, tennantite, magnetite and, coasionally, tinstone,
The vein mineral consists of manganosiderite, calcite, garnet, quartz,
barite, epidote, and others.
The composition of the minerals varies with the depth of occix,renoe.
In the shallower beds of the hypothermal zone the quantity of heavy silicates
of copper pyrite and magnetic pyrite is.smaller, while the amount of quartz
anal calcite is larger.
In?several sectors of the deposit an outcrop of bismuth is observed,
Certain places also contain cadmium.
Manydepo-ite do not contain a zone of oxidation. In the Tetyukhe
deposit, pipe-shaped beds of oxidized ore form individual pockets, which lie
apart from the in pyritio?body.
The.oxidized'ores consist of smithsonite, hydrozinclte, willemtte,
oerunette, amlaohite, azurite, pyroluzite, and brown iron ore. Of the larger
deposits the following should be mentioned:
a. `1etyu.ae deposi ,.which is the largest explored polymetallic de-
posit of the Sikhote Alin Oro district. The deposit is located on a high
ridge of the left bank of the Borisov ravine and the Tetyukhe River. Pyritic
ore consists of zinc blends, lend glance, copper pyrite, retie pyrite,
pyrite, eresnopyrit?, and Copper glanoe. The vein material is made up of
the.m.,lite, sanganosiderite, calcite, partly also of barite, , rz et, and
ilvaite.
Of the other deposits of h~, Primorek Rayon, the following deserve
marathon: Kirillcvsk, Kisinak, Gorbuehinak, and Shcherbakovsk. All of the
mired ore is sent t,~ the Tetyukhe dressing plant.
As a result of selective flotation, two kinds of concentrates h-3
obtained: lead and zinc. Lead ooncentratee are processed locally at the lead
smelting plant. Zinc concentrates, pending the construction of a plant in th-
local mining area, are shipped to the existing zinc plants.
2. Eastern Traiebayxal Deposits
The majority of the Eastern Tr, ..: n.:ro Rerchinak Asyon) deposits
are located in the territory between the Shiika e.nd Argun 'a rivers and the
Transbaykal railroad.
Almost all deposits of the Eastern Transbaykal occur in limestone and
dolomite>
Herehinsk ores are divided into oxidized and primary ores. The zon3
of carbonization is shallow.
The Rerchinsk deposits are characterized by a large variety of metals.
They contain lead, zinc, copper, silver, arsenic-, gold, tin, antimony, wolfram,
and several other elements; Leneo, the unusually complex mineralogical composi-
tion of these ores. The oxidized tune includes the following minerals: limonite,
ceruesite, emitheonite, mimetesite, and scorodite. Ronore elements are repro:
sorted by various carbonates and quartz. Primary ores consist of minerals such

as pyrite, areenopyrite, zinc blonde, gale.-i:_e, bouleaigerite, and pyrrhotine.
In isolated case6 marcasite, naseiterice, and other minerals are encountered.
Nonmetallic minerals include calcite. dolomite, manganosiderite, quartz,
sericite, and turmaline. The ores belong to the ingrained type; massive ores
are rare.
The Nerchlnak region is considered to have large potential reserves
of lead, zinc, silver, arsenic, and other metals.
The Salair deposits of polymetallic ores are found in the northeastern-
slope of the Salair mountain range, in West Siberia. They contain lees metal
than the genetically related Altay deposits.
Thoore is located along the longer axes of the ellipse of the
deposit. ;A large number of thb deposits have the form of irregular lenticular
bodies. Deposits in the oxidized zone represent ocherous barites with signifi-
cant contents of silver and gold.
The composition of the rock la the Salair deposits to rather even.
In the upper horizon the ore consists of quartz-barite, or just barite. In
;telover horizon the ore is barite and quartz or barite and quartz carbonate.
Sulfides are present in the form of minute Impregnations and are
usually distributed evenly throughout the ore mass. On rare occasions sul-
fides are concentrated in the form of bands,
W, The following mineral ores are to be found in the Salair deposits:
ephalerite, pyrite, galenite, tetrahedrite, copper pyrite, tennantite, '
oovellite, chalopsine, silver gldnre, cer'nesite, native silver; a.e1 gold.
Quartz and bari.te make up the gar;j.,o.
Ore extracted in the Salair mine Is processed the the Salair dress-
ing plant. Throe kinds of concentrates are obtai.n:d in thr process of selec-
tive flotation: zinc, lead, and barite.
Altay polymetallic deposits are located in the southwestern spire
and foothills of the Allay Mountains.. This is the most important USSR area
for the production of lead and zinc.
Besides zinc and lead, Altay ores also contain copper, cadmium, anti-
mony, eil:er, and gold. In respect to precious metals, Altay deposits occupy
an exceptional position. The large amounts of gold and silver in the upper
oxidized horizons of individual deposits stimulated the early exploitation of
these deposits, which began many years ago.
At present, with the development of methods for the reprocessing
of sulfides and poor ores, the Altay deposits occupy one of the first places
in the USSR.
Ore deposite occur here amid limestone and tuff, lead and porphyry.
Morphololieally the Altay deposits are quite diverse. Complex deposit's
predominate. Usually, deposith "dt uninterrupted pyritic ores occur with fairly
extensive zones of phenocrysta. The primary pyritic ores of the polyaetallic
deposits consist of pyrite, ephalerits, galenite. chalcopyrite, and tetrahedrlte.
Arsenopyrite and pyrrethine occur less fre;uently.

Gold is found in pyritic ores in nntive state and frequently in the
form of tellurous compound.
Gangue minerals include quartz, barite, and small amounts of carbonates,
cericite, and chlorite.
In many deposits there is a masked zonal traneformauion.in the character
of the ore, which depends on the depth of the ore's occurrence,' The amount of
spbalerite and pyrite is increased, and barite takes the place of quartz.
Oxidized ores contain gold and silver with sma.11 amounts of zinc.
The Altay area may be divided into six fielded
a. Leninogorsk field with the large Leninogorek and Sokol'nyy deposit's
and the smaller Kryukovsk, Il'insk, Uspenek, and Filippovek deposits.
b. Zyryanovsk field with the large Zyryanovek deposit and a number
of smaller deposits, such as Zavodinek,Bukhtarminsk, and others.
c. Irtysh field with Belousovek and Berezovsk, Nikolayevek, Talovok,
and other depoelts:
d. Zmsinogorskfield with the large Zmeinogorsk and Petrovsk deposit.gf
and the smaller Semenovsk,Cherepanovsk, and other deposits.
At present, the first four of the above-_,amed oze fields have an
industrial significance. These four fields have large reserves of polymetallio_
ores containing prec'oue metals.
Of all the above-mentioned regions the Lezinceorsk group has the
largest actual and indicated reserves.
Sara-twa region, in southern Kazakhstan, is an important poiymetallic
ore region, The ore minerals include galenite, ephalerite, pyrite, and occa-
sionally oha'.aopyrite, and crsenopyrite. The gangue is made up of calcite,
dolomite, siderite, and occasionally there is quartz and barite. The ore of
the ram-tau region is slightly silvery.
On the surface of the deposit the ore is almost always oxidized and
not infrequently the zone of oxidation attains great depth. Zinc is sometime
found in a leached state and is deposite' beyond the limits of lead ore, form-
ing a secondary accumulation of slmoet pare oxidized zinc ore with a emall Leal
content.
Oxidized ores are highly ferrouc. They are porous, have a yellow or
red-brown color and consist of ocherous, sometimes clayey ircn ore which con-
tains the oxidized lead and zinc minerals, In the oxidized zone lead minerals'
are represented chiefly by cerussite, angleeite in insignificant amounts, and
plumbodzhorosite L . Zinc appears as smitheonite, hydrozincite, mangemite
(carbonate of iron and. ?inc), and also as a peculiarly soft (stearin-like)
silicate of aluminum and zinc, containing Al and Zn in varying ratios, irio-
morphically replacing each other.
Nearly all lead-zinc deposits of the Sara-tau region are located in
the Central Sara-tau (Turlan, Santagi, Mirgalim-say, Kara-say and others).
The Baydzhansay and Suleymensay deposits are located separately in Southern
Kara-tau.

Of all the Sara-tau deposits the la,-geot and beet explored is the
Turlan deposit.
Pol'ymetallic ore deposits are located in the southern elope of the
Karamazar Mountains (lizbekistan).
The Sarama,zar deposits may be divided into two geological groups:
;,.those found amid volcanic rocks and those connected with 11mestone.
Deposits found amid volcanic, rocks belong to the hydrothermal type
having sulfide polymetallic ores of complex composition. The basic metals of
these deposits are lead, silver, zinc and iron, and to a lesser extent, copper;
Som ores also contain antimony, arsenib, cadmium, gold and, in exceptional
cases, wolfram, molybdenum, and uranium; The upper zones of the deposits con
tain oxidized ore. Of the ina.ividualdeposits of this group, San-i-Minsur and.
Tary-Bkan deserve mentioning.
Deposits of the second group, occurring in limestone, consist of rich
polymetsllic ores which Contain chiefly sulfides; lead and zinc, occasionally
arsenic, iron, and copper.. San-say, Takeli, Altyn-Topkmr, and Yuzhnaya Darlaza
belong to the deposits of the second grout.
7. Northern Caucasus Deposits
Lead deposits in the Northern Caucasus-are to be found in Sadon (in
Northern Oeetiya) and Ba?ka::ek, Karachayevsk, Chechenek, Adygeyek and Samursk
rayons (Dagestan).
The most important is the Sadon region where the largest lead deposit
iiI{the Caucasus is located. Smaller deposits are the Buronsk, Zgidek, Hhol.
stink, and Arkhonak.
The Sadon polymetallic ore deposit is located at the notch of the
Sadon River and its left tributary, the Kholdon. The deposit occurs amid
granite of an ancient age in the form of irregulrr veins, bisected by a
n ber of fnulte. The vein appears to consist of separate lenses which, with
a `ew exceptions, do not extend very far horizon.te.lly ar vertically,
The ore mined in the Sadon deposi is shipped to the dressing plant
in Mizur. After selective flota'Son, two kinds of concentrates are obtained:
lead and z1m .
Concentrates from the Mizur dressing plant are shipped to the lead-
zinc plant at Ordzhonikidze.
