【摘要】 根据入选原矿性质,经过试验确定:云南昆阳磷矿及晋宁磷矿单独选别可采用单一反浮选及常温正反浮选流程,昆阳、晋宁混合矿可采用常温正反浮选工艺流程。三种工艺的技术经济指标对比和分析结果表明:常温正反浮选流程最适合选别以2∶1比例组成的昆阳、晋宁矿混合矿。更多还原

【Abstract】 Based on the properties of raw ore,it was determined by tests that for Kunyang and Jinning phosphate rocks the single reverse flotation process and direct-reverse flotation process at room temperature could be adopted,and for the mixed ore of the two kinds of ores the direct-reverse flotation process at room temperature could be adopted.The results of comparison and analysis of technological and economical indexes of three kinds of processes showed that for the mixed ore of Kunyang with Jinning(2∶1),the direct-reverse flotation process at room temperature was the most suitable.更多还原
