This issue presents a versatile variety of publications in the sections “Processing Technology” and “Technological Mineralogy”.

The first includes the papers describing the testing results of a promising autoclave-hydrometallurgical low-grade concentrates conditioning technology, applied to pyrite copper-zinc ores (the paper by B. S. Ivanov et al.); practicability of joint processing of the Nurkazgan deposit Western and Northern areas ores is validated (the paper by I. I. Maksimov et al.); new developments of Outotec in the field of base metals ores flotation technologies with application of the latest automation means and process control computer programs are considered.

Two papers in the section “Technological Mineralogy” are dedicated to the ores of the Kola Peninsula.By the example of the Oleniy Ruchey deposit apatite-nepheline ores with low apatite content, effect of calcium ions upon flotation results is demonstrated, and the recommendations with regard to reagents regime correction and return water conditioning are presented (the paper byА. Sh. Gershenkopet al.). The study of forsterite varieties composition and surface morphology, selected from the Kovdor deposit natural ore types, applying the methods of X-ray micro-CT and SEM, permitted to ascertain the factors that lower floatability of the mineral in question (the paper by Ye. Ye. Kameneva et al.).

As ever, the papers dedicated to the issues of man-induced materials reclamation are of current interest. The Sorsky Mining Complex overburden rocks and sulfide molybdenum ores flotation tailings chemical, mineral and particle-size distribution analyses, conducted by the scientists of the Siberian Federal University (R. G. Yeromasov et al.), showed, that utilizing ore processing tailings as components in stoneware mix is most promising.
