However, the capacity of individ- ual installations was not over 50-100 tons per hour, witb the exception of the Kadiyevka plant, which had a capacity of over 100 tons per hour, and the equip- ment of the plants and the technology of cleaning was comparatively simple since stn-of-the-mine coal contained relatively little ash, particularly the small va- rieties below 3-4 millimeters in size.(2) 'a During the past 10 years, the productive capacity of cleaning plants in- creaecci almost four times. Zn 1940, only 19.4 percent of coking coal ores sub- Jected to mechanical cleaning, but in 1950 this figure had risen to 40 percent ~ource 2 says wore than 80 percent] and in 1952 to 50 percent.(1) From 1930 to 1940, very large coal-cleaning plants were constructed accord- ing to plans of Soviet specialists: the Kal'miueskaya TsOF (Tsentral'naya Obo- gatitel'naya Fabrika, Central Coal-Cleaning Plant and the Chumakovskaya TsOF in the Donbass, the Ka.sgandinskaye TsOF in Karaganda end a number of others with coke by-products pl zts (Yenakiyevo, Gubakha, etc.). The capacity of one coal- hriquetting and cleaning plant which was put in operation excee~?.ed the total ca- pacity of all briquetting installations of prerevolutionary Russia. USSR-made ' equipment, distinguished for Sts high productivity and increased effectiveness, is installed in all these plants. At present, all coking coal of such combines Sanitized Copy Approved for Release 2011/09/14 :CIA-RDP80-00809A000700120053-8 Sanitized Copy Approved for Release 2011/09/14 :CIA-RDP80-00809A000700120053-8 ae the Kuzbassugol' Combine, ~ourc~ 1 aaya the predominant part of Kuzbasaugol' Combine coal] is eub~acted to mechanical cleaning, while before 1940 th:s com- bine did not possess a single coal-cleaning ,:ombine.(2) In addition Yo the Kuz- bass, inten^_ive work is being done in the Donbass and Karaganda with the aim of reducing the ssh content of coal to be used for coking.(1) In 1950 alone, about 2,500,000 tons of harmful admixtures were removed by mechanical methods Prom coal shipped by enterprises of the?Miniatry of the Coal Industry. Shipping this coal in its uncleaned state would have required about 2,000 additional railroad trains. The ash content of coking coal shipped in the Fourth Five-Year Plan from coal-cleaning plants of the Ministry of the Coal Industry xas decreased from 9.7 to 8.1 percent in the Donbass, from 8.5 to 8.0 percent in the Kuzbass, and from 11.2 to 10.9 percent in Karaganda. The improved quality of this coal has contributed to higher achievr~ents in metallurgy. The ash content of fuel coal shipped to enterprises of the Ministry of Electric Polder Stations decreased in the Fourth Five-Year Plan from 17.10 per- cent (1945) to 15.9 percent (1950), while that of coal shipped to enterprises of thF Minis~ry of Railways decreased correspondingly from 24.21 to 23.05 per- cent. Th1a improved quality of fuel coal. resulted in a decreased consumption of 5.6 percent by enterprises of +.he Ministry of Electric Pawer Stations and of 19.6 percent by enterprises of the Ministry of Railways. In prerevolutionary Russia, coking coal in sizes below 3-4 millimeters was not cleaned; at present, all small sizes of coking ccals are cleane3 in Donbass pleats. Screening techniques have changed greatly in USSR coal-cleaning plants. Law-performance shaker screens have been replaced by high-speed BKG shaker screens and by VG and GUP vibration screens. Flotation, a new process of cleaning small particles of coal, is being used widely on an industrial scale in enterprises cf the coal and coke by-products industries. In 1953, flotation installations of the Donbass are processing several thousand. tons of coal par*icles per day. Flotation. has greatly decreased losses of high-grade coking coals and is spreading not only in the Donbass but in the Kuzbass and Karaganda. During the Fifth Five-Year Plan, several of the largest flotation instal- lations in the world will be put ~enepofacellsiofthi elsteroductivesflotation TaOF in Karaganda alone, several gh Y P machines will start operating. The average capacity of a flo*ation installation in the Donbass is about 40 tons per hour. F.lmest all flotation reagents u=ed in flotation installations of foreign countries and, until recently also in the USSR, are products of the coke by- products industry. These reagents con~ain a number of harmful substances; as a result, used rater carried ofn from tflotationiinstallationsoof phe Ministrvuoaf7. rater reservoirs. Et?arting 951, the Coel Industry began to use reagents which did not contain harmful ingr_:i- enta end in this way increased the efficiency of the flotation process and de- creased i+s cost. Soviet specialists are mastering a chemical-gravity method for removing ash and sulfur from coking coal. ,With the introduction of thlieseofocokinincoalrwiil the sulfur content of coal wiry decrease sharply and ~c~pF g be increased.

An instal- lation for this purpose has been operating more than 2 years in the Sverd- lovskugol' Combine and is cleaning high-ash conl fror. the Volchansk deposit. Good results have been obtained at a coal-cleaning plant at Mine No bk-45 and Mine No 46-47 of the Kopeyskugol' Trust of the Chelyabinskugol' Combine. The conclusion may be drain that the wet process of cleaning will produce a high-grade lignite concentrate. If the ash content of the originsl coal was 36-38 percent, that of the concentrate x111 be 18-20 percent.(2) The directives of the 19th Party Congress provide for an increase of 2.7 times in coal-cleaning during the Fiftb Five-Year Plan. The amount of coal processed in coal-cleaning plants ie to increase 2.9 times, including 2.3 times for coking coal, 4.7 times for fuel coal, and 16 times for lignite.(1, 2) SOURCES 1.
