STUDYING THE METAL- COMPOSITION OF THE TECHNOGENIC RESIDUE OF MINERAL RAW MATERIALS OF REPUBLIC OF ARMENIA

Abstract

It is shown that the solid residue of production of a metallurgical enterprise of Republic of Armenia is metal-bearing: that is, it is based on silicon dioxide, a technogenic product, that, in addition to black metal oxides and sulfides, iron, manganese and chrom­i­u­m, it contains complex chemical compounds which are resistant to oxides, absorbed with both non-ferrous and rare nobel metals.
