处理含有超细粒共生的稀有金属、稀土元素、锡以及有用脉石矿物(云母、萤石、钠长石、微斜长石)的复杂矿石时,需要联合使用多种富集方法与水治操作技术。使用有机膦化合物,例如膦酸及双膦酸,发展了选别稀有金属和锡矿的浮选流程。当有用矿物和脉石矿物浮选性能近似时,用这些化合物进行分选,具有高度选择性。研究了碳链长度为6～9个碳原子的双膦酸化合物的浮选
When dealing with complex ores containing rare metals, rare earth elements, tin, and useful gangue minerals (mica, fluorite, albite, and plagioclase) with symbiotic superfine particles, a combination of multiple enrichment methods and water treatment Operating technology. Using organic phosphine compounds, such as phosphonic acid and bisphosphonic acid, flotation processes have been developed that distinguish between rare metals and tin. When useful minerals and gangue flotation performance similar to the use of these compounds for sorting, with a high degree of selectivity. The flotation of bisphosphonic compounds with a carbon chain length of 6 to 9 carbon atoms was investigated
