摘要
Abstract
Nickel ore resources in China are mostly low-grade sulfide ores with high percentage of MgO-containing silicate gangue minerals.Flotation is the main way to concentrate copper and nickel metal.However,the percentage of MgO in flotation concentrates is generally high.Flash smelting requires MgO content must be less than 6.5％.High content MgO in concentrate may cause smelting furnace temperature rise,slag viscosity increase,furnace junction,difficulty in slag separation,which results in lower smelting recovery rate and higher smelting cost.In this regard,the domestic and foreign researchers have done extensive studies.But the problem that reducing MgO content leads to high loss rate of copper and nickel is widespread.Reducing MgO content in the concentrate of copper-nickel sulfides is a difficult problem in mineral processing.The research progresses on reducing MgO in the flotation concentrate of copper-nickel sulfides were summarized in this paper,and the reduction mechanism and development trend were also analyzed.关键词
