贵州省瓮安磷矿属海相沉积磷块岩矿床,矿石储量大,矿层厚,纵横稳定,规律性强,矿区交通方便,将是我国较大的磷矿基地之一。 我们从一九七五年九月至一九七六年十二月,先后进行了瓮安磷矿的选矿探索试验和小试验工作,试验证明可选性是良好的,采用不同的选矿方法均可获得质量较高的磷精矿产品,可以作为生产高效复合肥料的原料。本文仅就试验结果作一简单的介绍。 Weng’an Phosphate Mine in Guizhou Province is a marine sedimentary phosphate rock deposit with large ore reserves, thick ore bed, stable vertical and horizontal, strong regularity and convenient transportation. It will be one of the larger phosphate rock bases in China. From September 1975 to December 1976, we conducted a series of beneficiation exploration tests and pilot tests at Weng’an Phosphate Mine. The tests show that the selectivity is good and all the beneficiation methods High-quality phosphate concentrate products are available as raw materials for efficient compound fertilizers. This article only on the test results for a brief introduction.
