合理利用卡拉套矿区的磷块岩,有助于大大增加原料资源,用以生产市场上十分缺乏的矿物质磷肥,同时还有利于提高质量和降低成本。 卡拉套矿床的磷矿石在破碎和筛分以后,10～50毫米的粒级是电热法制取黄磷的原料。为黄磷厂生产的商品矿石正在不断增加,不久将超过1000万吨/年。此外,目前还在生产两种用于酸法加工的磷块岩原料:磷矿粉(干磨扎那塔斯矿床地表带最富的矿石)和浮选精矿(入选矿石为选出10毫米粒级商品矿石后的尾矿和采自楚拉克套矿山的部分矿石)。所得到的产品含有28％P_2O_5和2％MgO。将来还计划生产
The rational use of phosphorite in the Kalatai mining area will greatly increase the raw material resources for the production of mineral phosphate, which is very scarce in the market, and will also help improve the quality and reduce the cost. Phosphorite Kalatao deposit after crushing and screening, 10 to 50 mm particle size is the raw material of electrothermal yellow phosphorus. Commodity ore produced for the Yellow Phosphorus Plant is on the rise and will soon exceed 10 million tons / year. In addition, two types of phosphorite raw materials for acid processing are currently being produced: phosphate rock (the richest ore belt in the dry-ground Zanatz deposit) and flotation concentrates (selected for the selection of 10 mm Tailings of grain grade ores and some ore from Churak set mines). The resulting product contains 28% P2O5 and 2% MgO. In the future also plans to produce
