Abstract | Sokolovsko-Sarbaiskoe Mining and Concentration Production Association is the largest Kazakhstan and CIS producer of metallurgical raw materials of concentrate and pellets. Magnetite iron ores are supplied to ore-preparation complex from Kacharskiy, Sarbaiskiy, Sokolovskiy and Kurzhunkul open pits, and from Sokolovskaya mine. At the same time, physical-mechanical, chemical and technological parameters of these objects’ ores are significantly different. This article describes the process of week-daily planning for ore averaging with various technological indices, supplied to ore-preparation complex of the Association from Kachkarskoe, Kurzhunkul, Sarbaiskoe and Sokolovskoe deposits. This article also gives the following information: order of technological sampling; requirements to the slimes’ samples on weight and granulometric composition; order of research of slimes by department of technological control on grindability; chemical composition with following schedule plan calculation with application of special software. |
