黄麦岭磷矿是一大型沉积变质磷灰岩矿床。尽管矿石易采易选,但碳酸盐的抑制也相当困难,许多科研单位对此进行了广泛研究,本文将对研究结果作一综合评述。 一、矿石性质 黄麦岭磷矿上层为风化矿,下部为原生矿,碳酸盐矿物主要赋存在原生矿中。有用矿物主要为氟磷灰石及少量黄铁矿,脉石矿物主要是石英、微斜长石、白云石、白云母、 炭质,石墨等。 磷灰石矿物粒度一般介于0.08～0.3毫米,常与石英、长石、白云石密切共生。碳酸盐以白云石为主,仅含少量方解石。形状多呈不规则粒状,不均匀分布,常充填于其它矿物间隙中,粒度介于0.1～0.6毫米。
Huangmeiling phosphate rock is a large sedimentary metamorphic apatite deposit. Although the ore is easy to choose and easy to choose, the inhibition of carbonate is also quite difficult. Many scientific research units have conducted extensive research on it. This article will make a comprehensive review of the research results. First, the nature of Ore Huangmeiling upper phosphate weathering mines, the lower part of the primary ore, carbonate minerals mainly present in the primary ore. Useful minerals are mainly fluorapatite and a small amount of pyrite, gangue minerals are mainly quartz, slightly plagioclase, dolomite, muscovite, carbonaceous, graphite and so on. Apatite mineral particle size generally between 0.08 ~ 0.3 mm, often with quartz, feldspar, dolomite closely together. Dolomite carbonate-based, containing only a small amount of calcite. Mostly irregular shape of the shape, uneven distribution, often filled in other mineral space, particle size between 0.1 ~ 0.6 mm.
