Polymetal has completed the next stage of development of Amursky MMC
Polymetal has implemented the 3 Phase project, aimed at expanding and modernizing the Amursky hydrometallurgical plant, which specializes in processing refractory gold-bearing ores. The total investment in the modernization project of the AGMK amounted to 71 million.
The work was carried out in connection with the launch at the end of June 2018 of the beneficiation plant at the Kyzyl deposit (Republic of Kazakhstan). AMMK processed the first gold-containing concentrate from Kazakhstan in October 2018 of the year. It is assumed that the modernized plant will process 50% concentrate produced in Kyzyl.
According to the press service of the Khabarovsk branch of JSC "Polymetal", now at the plant are conducting the commissioning of the new technological scheme. AGMK will operate with increased productivity, processing 180-200 thousand tons of concentrate per year.
“The completion of the third stage of the modernization of the plant was an important step in the implementation of the strategic goal of the company Polymetal - the creation of the Center for the processing of concentrates of gold ores on the basis of AGMK in Amursk. The growth of the plant’s capacity is a reliable base for the creation of new jobs in Amursk, and AMMK’s unique technologies are a guarantee of the long-term sustainable development of the enterprise, provided with a resource base and a reliable team of professionals. This is an opportunity to continue to make a significant contribution to the development of the social sphere and the improvement of Amursk, because most of the AMMK team is Amur residents, ”said the director of the Khabarovsk branch of Polymetal JSC Valentin Martynenko.
For three years, new sites were built at AGMK (thickening, neutralization, filtration of gypsum sediment, filtration of leaching tailings), new auxiliary facilities (oxygen station No. 2, desorption section No. 2), modernized 17 production facilities at ten operating production sites, including heat recovery and circulating water purification system.
In the course of modernization, advanced technologies were used and added to the production process that reduce the environmental impact: cooling of circulating solutions, neutralization of acidic solutions and sulfur removal, a unique system of closed water circulation. During the year, about 100 new employees took on the tasks of expanding production at AGMK, 95 of which were residents of Amursk and Amursky district.
“The uniqueness of the AGMK modernization project is that it was implemented in a short time. At the same time, specialists of the company found solutions that allowed including additional equipment and new facilities into the technological scheme of the existing autoclave line without additional stops of the enterprise. All three years, the plant continued to operate at full capacity. The final result of the project was the opportunity to increase the processing of sulphide gold-bearing concentrates, while maintaining the constant planned extraction of gold at the level of 96%, ”noted AMMK managing director Vadim Kipot.
