Abstract

The results of long standing studies by collective of the laboratory of vacuum processes JSC “Institute of Metallurgy and Ore Benefication” provided the basis for the development of environmentally friendly vacuum-distillation technology of selenium extract from the various selenium-containing middling products and materials with further refinement to the slate condition in accordance with GOST 10298-79. The technology and equipment has been tested on different raw materials, including: technical and crude selenium produced by Kazzink LLP and Kazakhmys Corporation LLP, selenium-containing bag filter fumes of refinery production and drilling cutting of sulfuric production produced by Kazakhmys Corporation LLP, sludge of nickel production produced by Kolsky MMC, selenium-containing concentrates Krastsvetmet JSC. Potential of developed vacuum-distillation technology and equipment, allowing to receiving the selenium containing more than 99.5 % of the main component within one step by cheap reagentless method, is shown in this article an example of several form of materials
