Obogashchenie Rud

The section "Ore preparation", which traditionally opens the number, turned out to be the most representative. The results of research on the selection of technology and equipment for crushing and classification of glassapatite (phosphate glass), brittle material used in agrotechnics as a fertilizer for prolonged action, as well as in a number of new medical technologies (the article by V. V. Gladkova et al.) are interesting. Analysis of the possibility of transition from three-stage to two-stage grinding at the concentrating mill of Kachkanarskiy GOK is also worthy of attention. The scheme with verifying classification and control screening in the second stage is recognized as the most promising among the two-stage schemes (the article by A. E. Pelevin and N. A. Sytykh).

The section "Beneficiation Technology" provides a detailed overview of technological studies of the low-sulfide ores of the gold deposit in Chukotka, conducted by institutes VNII-1, Irgiredmet, TsNIGRI, TOMS. Based on these studies, a scheme for ore deposit beneficiation is proposed, which provides for the gradual extraction of gold by gravitational methods with the direction of the concentrate obtained in the hydrometallurgical processing (the article by P. K. Fedotov et al.).

Environmental protection topics are presented by research into the ways to clean the drainage waters of the tailing dumps of JSC "Apatit" from molybdenum. As a sorbent, it has been proposed to use steel shavings activated by treatment with de-ionized water in the open air. The proposed technological solution allows to ensure the purification of waste water from molybdenum by 92-96 % (the article by V. A. Matveeva et al.). In order to reduce capital and operating costs for the storage of tailings of beneficiation and recycled water supply, studies have been carried out on tailings processing with Rheomax ETD rheology modifiers. It is found that the use of these modifiers contributes to the formation of a condensed precipitate of a strong homogeneous structure that is practically unaffected by spreading and has high water loss. This technology is applicable for the effective thickening of tailings of flotation and their subsequent laying in the tailing pond, as well as for the treatment of mine waters of underground mines with a high content of sludge particles (the article by I. V. Shadrunova et al.).
