由于矿物日益复杂,较低品位矿石贮量不断增加,过去十年来,经受经济衰退困难时间,工业上能经济地处理这些物料必须加速研究出新的工艺技术。虽然,大多数的技术革新,例如溶剂萃取,离子交换等已经在化学选矿领域广泛采用;而且,在物理选矿领域内,除了使用电子计算机,和较大单体工艺设备以 Due to the increasing complexity of minerals and increasing reserves of lower grade ore, it has been necessary to speed up the development of new process technologies in the industrial economy in the past 10 years to withstand the difficult time of an economic downturn. Although most technological innovations, such as solvent extraction, ion exchange, and the like, have been widely adopted in the chemical beneficiation sector, and in the field of physical beneficiation, in addition to the use of electronic computers and larger monolithic process equipment
