开阳磷矿是我国大型磷矿之一,它的储量丰富,质量高,是发展高效磷肥和复合肥料的重要原料基地。该矿为倾斜、缓倾斜矿体,由于在开采过程中混入有较多的围岩而贫化了磷矿石,为解决这部分混入的白云石,马路坪矿段大于6毫米级别用光电选矿加以剔除(详见化工矿山技术1984年第五期)。而细粒级通过常温反浮选,也同样得到了高质量磷精矿。本文就浮选情况加以简单介绍。
Kaiyang phosphate rock is one of China’s large-scale phosphate rock, which reserves rich, high-quality, is the development of efficient phosphate fertilizer and compound fertilizer an important raw material base. The mine is inclined, gently inclined ore body, due to the inclusion of more rock in the mining process and depleted phosphate rock, in order to solve this part of the mixed dolomite, Maluoping mining section is greater than 6 mm level by photoelectricity dressing To be removed (see Chemical Mining Technology 1984 fifth period). The fine-grained anti-flotation at room temperature, also received high-quality phosphate concentrate. This article gives a brief introduction of flotation.
