摘要
瓮福磷矿a层矿为沉积型硅钙质磷块岩,b层矿为典型的沉积型钙(镁)质磷块岩,前者选矿工艺复杂、选矿成本高、回收率低,后者已连续生产12年。为了更好地开发利用a层矿,本研究对a、b混合矿进行了选矿小实验和工业试验。工业试验结果表明:利用现有的一次反浮选选矿工艺和药剂制度进行(a+b)混合选矿是可行的,而且药剂用量比单独选别b层矿时的药剂耗量少,回收率高,混合精矿达部标优质Ⅱ类产品要求。
The a layer ore in Wengfu Phosphate Mine is sedimentary silicon-calcium phosphate rock. and the b layer ore is typical sed- imentary calclum-magnesium phosphate rock. The beneflciation pro- cess of the former is complex, and its beneficiation cost high and its recovery low, whereas the latter has been produced for 12 years. For better utilizing the a layer ore, small experiment and industrial experiment of mixed ores of a layer ore with b layer ore were carried out. The results of industrial experiment showed that utilizing current reverse flotation process and reagent system to beneficiate （a ＋ b） mixed ore was feasible, and its reagent dodge was less than the dosage of single beneficiating b layer ore, and its recovery was high. The mixed concentrate achieved the professional standard of high quality Ⅱ class product.
