Abstract

In 2010–2011, the specialists from Science and Production Association "RIVS" held the technological audit of Gai Processing Plant and the development of technological regulations on the processing of ores of the current and prospective extraction of Gai deposit. During this audit, there have been held the analysis and estimation of the installed equipment and technological schemes of the main concentration redivisions, on the basis of which, there were defined the main directions of the reconstruction of the processing plant of Gai Mining and Processing Combine, including the following operations:
• there was developed the rational combination of the existing crushing powers of the main building, as well as the introduced and planned semi-self-crushing complexes to provide the feed size processing of the main bulk flotation and the ore capacities, approved by the prospective mining plan;
• there was defined the optimal technological scheme of the ore concentration of Gai deposit;
• there were defined the dimension types of the main flotation and auxiliary equipment and there was developed its optimum arranging scheme;
• there were formulated the basic modernization directions of the management system by the technological process on the processing plant, including the testing, control and automation of equipment, applied on all departments of the factory.
According to the results of the aggregative technical and economic calculation, the payback period of all recommended measures will be 4.5 years.
Nowadays, Science and Production Association "RIVS" realizes the reconstruction project of the processing plant of Gai Mining and Processing Combine. At the same time, there is held the assembly of new flotation equipment and the replacement of the worn-out aeration units.
