MLA技术在某铜钼矿选矿工艺研究中的应用

Application of MLA Technology in Process Mineralogy Research on Copper-molybdenum Ore

MLA是目前世界上最先进的工艺矿物学参数自动定量分析测试系统之一。目前国内MLA技术主要用于指导选矿工艺研究,以要进行选矿加工的矿石为研究对象,为选矿流程提供矿物组成、含量、目标矿物嵌布粒度、磨矿产品解离度、伴生元素赋存状态等信息,指导确定选矿工艺,提高选矿试验研究效率。本研究采用MLA技术指导某铜钼矿选矿工艺研究。根据MLA工艺矿物学研究结果确定选矿工艺和药剂制度,通过条件试验确定详细的工艺参数和各药剂用量,最终在原矿铜品位0.63%、钼品位0.022%的条件下,得到铜品位24.82%,铜回收率91.90%,钼品位35.15%,钼回收率57.56%的选别指标。与现场生产指标相比,铜回收率接近,钼回收率提高12%。

MLA technology is currently one of the most advanced automated quanttative mineralogy in the world. At present MLA technology is mainly used for guiding experimental research on mineral processing. Ore needed for mineral processing is the object of study,providing mineral composition,content,target minerals disseminated extent,grinding dissociation degree,state associated elements,such as information to improve the efficiency of experiment research. The study adopted MLA technology to guide the mineral processing of the coppermolybdenum ore. According to the result of MLA process mineralogy study,the processing technology and reagent regime was determined. A detailed technical parameters and the dosage of reagents was determined by condition experiments. Finally,under the condition of undressed ore of copper grade of 0. 63% and molybdenum grade of0. 022%,indicators of grade of copper concentrate of 24. 82% and recovery of 91. 90%,grade of molybdenum concentrate of 35. 15% and recovery of 57. 56% was got. Compared with the field production index,copper recovery rate was close to and molybdenum recovery increased by 12%.
