The article discusses the results of technological studies on the concentration of polymetallic ore of the Chinarsay deposit. The results of studies of the material composition and flotation concentration options for technological samples of ore from the Chinarsay deposit are presented. The results of studying the material composition of ore based on spectral, chemical and rational analysis are presented. It has been established that industrially valuable ore components are lead, zinc and copper, the contents of which are given. It was shown that ore minerals are in close intergrowth with non-metallic ones - quartz, sericite, chlorite, carbonate, etc. It is noted that the studies were carried out in two directions: collective flotation of all ore minerals with further selection of the collective concentrate into lead, zinc, copper and pyrite concentrates and direct collective selective flotation to produce sequentially lead-copper, zinc and pyrite concentrates. As a result of enrichment, lead, zinc and copper concentrates are selected that meet the production requirements.

Flotation Concentration

Previous studies at a number of research centers in our country, including the Institute of Mining, SB RAS and the Institute of Nuclear Physics, SB RAS, showed the possibility of improving process parameters of flotation concentration of difficult mineral raw materials due to preliminary electron-beam processing, which allows weakening minerals and rocks. Obtaining the data on selective disintegration and disclosure of minerals during ore pretreatment is important for technological application. This study aims at receiving the experimental data confirming an increase in the selectivity of disintegration of mineral raw materials processed by a high-energy electron beam and an improvement in the disclosure of intergrowths of useful minerals. Complex experimental mineralogical and technological studies by the example of rebellious lead-zinc ore with a grain size of -3 mm provided the data on increasing the selectivity of disintegration of mineral raw materials and improving the disclosure of useful minerals. It is found that if in -0.071 mm size class of ground lead-zinc ore without processing, the fraction of free galena and wurtzite grains (sphalerite modification) is 40.7 and 65.7%, then the fraction of free grains of these minerals increases up to 66, 4 and 71.5% in ore pretreatment. It should be noted that ore processing by accelerated electrons allows obtaining the ground material, in which free mineral grains are less overground. For galena, the size of free grains increases from 2.6 to 4.0 μm, and for wurtzite - from 4.5 to 6.6 μm. Scientific novelty includes increasing the selectivity of disintegration and improving the disclosure of useful minerals through the effect of weakening of mineral raw materials in ore pretreatment.

Abstract Copper Alloy No. 844 is a free-cutting copper-tin-lead-zinc alloy for castings; it was formerly identified as 81-3-7-9 alloy. It is characterized by good casting properties, moderate strength and ductility, good machinability and good resistance to corrosion. It is used widely for fittings, plumbing goods and valves. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-349. Producer or source: Copper alloy foundries.
