宜昌磷矿属特大型浅海—滨海沉积磷块岩矿床,具有地理、交通、资源、能源四大优势,是我国重要的磷业基地。为加速开发该矿,先后进行了浮选、反浮选、擦洗—光电选、光电—反浮选、化学选矿及重介质选矿研究,积累了宝贵经验。 一、分选情况 由于矿石中P_2O_597％分布在磷块岩中,84％的镁分布在白云石中,79％的硅和85％的铝分布在页岩中,铁一半以上分布在磷块岩中,有害杂质大部在脉石条带中,适合重介质选别。
Yichang Phosphate Mine is a large-scale shallow sea - coastal sedimentary phosphorite deposit, with four advantages of geography, transportation, resources and energy. It is an important phosphate industry base in China. In order to speed up the development of the mine, it has successively carried out research on flotation, anti-flotation, scrubbing-photovoltaic selection, photoelectric-reverse flotation, chemical beneficiation and heavy medium beneficiation, and accumulated valuable experience. First, the sorting situation As the ore P_2O_597% distribution in the phosphorite, 84% of the magnesium in dolomite, 79% of the silicon and 85% of the aluminum in the shale, iron more than half of the distribution in the phosphorite In most of the harmful impurities in the gangue band, suitable for heavy media sorting.
