Research of Material Content on Drop Layout Waste of Marjanbulak Gold Extracting Factory

Abstract

The article presents the results of the analysis of the material composition of a technological sample obtained from industrial waste at the Marjanbulak gold recovery plant. The material composition of the waste samples was studied using spectral, chemical, rational, optical emission spectral, mineralogical, particle size distribution and other types of analyzes. The main industrial components of the sample are gold and silver. According to the results of laboratory studies, the content of gold in the waste of MGRP is 0, 61 conventional units, silver – 11, 61 conventional units. The waste contains an additional rare earth element, the total amount of which is 169,2 g/t. The investigated technological sample belongs to the mixed type, in which gold is found in pure form and in the form of an electrode. It is not visible in gold sulfides and in terms of size refers mainly to fine and dusty classes. The size of gold micro particles is 0,001-0, 05 mm. According to the results of laboratory analysis, the minerals and minerals of gold in the waste are slightly lower in quality and quantity than in the original ore, which negatively affects the enrichment of the waste and leads to low enrichment ratios.
