The third issue of the journal opens with publications devoted to beneficiation as a technology and its individual processes. They present a combined processing of tungsten-molybdenum ores based on the differentiation of intra-block reserves using a new concept of lump sorting; the reagent mode of coking coals fine classes flotation is justified to improve the quality of coal concentrate and reduce waste; due to the high reliability of the neural network model, the effectiveness of using multifactor matrices for laboratory tests has been proven.
The article on technological mineralogy provides data on the content of native gold in complex placers of natural and technogenic origin in Russia. The basic technological scheme of the associated extraction of free gold into an independent commercial gold-containing concentrate is also presented.
