ABSTRACT
Almost all the deposits of Kazakhstan mining-metallurgical complex (MMC) are the multi-component ones. Their ores contain large enumeration of very important metals and non-metals. Complete use of the last ones is the urgent problem of MMC. Its solving envisages making a careful study of the deposits’ geology, ensuring of the most complete excavation of reserves and extraction of all useful components from mineral raw materials (MRM). For impartial assessment of MRM complex use it is necessary to have information about the quantitative indices of MRM treatment by the different technological processes. The coefficient of effective use (CEU) of MRM is considered as such index. It is ratio of the usefully utilizing part of MRM at the considered stage of processing to its full mass (volume) before treatment.
