我国钨矿资源成份复杂,矿物赋存状态、可选性及选矿回收率,因时因地而异。选冶联合流程直接处理低品位中矿和黑白钨混合矿,生产仲钨酸铵在技术上是成熟的。特别是中南工业大学稀冶教研室,新近研究成功热磨碱法分解工艺,处理低品位难选钨物料,碱热球磨过程将磨矿、 The composition of China’s tungsten ore resources is complex, the state of mineral deposit, the selectivity and the recovery rate of mineral processing vary from place to place. The combined process of dressing and smelting directly deals with low-grade medium and black and white tungsten mixed mines to produce ammonium paratungstate technically mature. In particular, the Central South University of Technology Institute of thinning, the recent study successfully hot-alkali decomposition process, treatment of low-grade refractory tungsten material, alkali hot ball grinding process will be grinding,
