Abstract

The Republic of Kazakhstan has well developed non-ferrous metallurgy, however in connection with shortage of raw material resources decrease in overall performance of the enterprises of branch is noted. At the same time are found and studied large a field of copper-molybdenum ores — Aktogay, Koksay, Bozshchakul, Shatyrkul, etc. It is possible to consider as the main direction of development of non-ferrous metallurgy of Kazakhstan complex creation on enrichment of copper-molybdenum ores with the center for processing of molybdenic concentrates. Technological modes of flotation of copper-molybdenum ores now in use possess an essential shortcoming: owing to application in a cycle of collective flotation butyl xanthate the high consumption of lime is necessary for a depression of flotation of a pyrite. This circumstance leads to appreciable decrease in recovery of molybdenum and in passing taken precious metals. At a choice of technology of flotation it is possible to use a number of the development created by institute of Gintsvetmet, passed successful check in skilled industrial and industrial conditions. Action of the following collectors is studied: butyl and isopropyl xanthates, butyl dithiophosphates (Aerofloat), DMCE, DECE and CGCE reagents (derivatives dithiocarbamates) and non-polar collector. On the basis of laboratory researches to tests were recommended Aerofloat and DECE reagent, as collectors the most selective for a pyrite. For selection collective copper-molybdenum product MFTC reagent is offered instead of usually being applied sodium sulphide. These decisions allow to increase recovery of molybdenum and accompanying precious metals in comparison with the traditional technology applied at flotation of copper-molybdenum ores.
