Two-stage turnkey construction of a 6.0 million ton magnetite concentrate flotation finishing unit.
Year: 2003, 2008, 2013
RESEARCH. In 2003 the technology of flotation finishing of magnetite concentrate was developed. In 2011-2012, a technology for beneficiation of oxidized ferruginous quartzites with semi-industrial tests was developed.
DESIGN. In 2003 the RIVS Company performed the complete set of main and auxiliary equipment for flotation conversion of the magnetite concentrate finishing unit with a capacity of 3.0 million tons on a turnkey basis. In 2008 based on the results of successful operation, the second stage of the finishing section with a capacity of 3.0 million tons was built.
In 2011 technical and economic assessment (TEA) was performed to develop a feasibility study for construction of a crushing and beneficiation complex for processing hematite ores with a capacity of 7.0 million tons of ore per year.
In 2013 TEA was developed: “Determination of the feasibility of involving oxidized quartzites in processing”.
EQUIPMENT. To ensure effective selection of the flotation process, six-chamber pneumatic-mechanical flotation machines of special design for beneficiation of magnetite concentrates RIF25CHM, equipped with automatic control systems for machine operation parameters were developed, manufactured and delivered.
The company's productivity was increased from 8,2 million to 20 million tons per year. The reconstruction was carried out without stopping production
