Purification of low grade molybdenite by acid leaching processes
High purity(>98%) molybdenum disulfide from molybdenite is an excellent solid lubricant,which can be used in automobile ,aerospace and military field.Molybdenite is the most widely used concentrate in the production of MoS2.Molybdenite usually contains some sulfide minerals such as covellite (CuS),pyrite (FeS2) and chalcopyrite (CuFeS2),and some other impurities like quartz (SiO2).The purity of molybdenum disulfide includes a series of refining step in order to produce high grade molybdenite concentrate.The removal of copper,silica and iron impurities from low grade molybdenite concentrate is very important.Ferric chloride solution containing ferrous chloride and hydrochloric acid is a strong kind of oxidizing lixiviant which is capable of leaching copper minerals such as covellite,chalcopyrite,chalcocite,ect.Hydrofluoric acid is best know to the public for its ability to dissolve silica.Sulfur is soluble in carbon disulfide .In this work,the purification of low grade molybdenite was taken in nacid solution.The ferric chloride was used as an oxidant,and FeCl2 was added in order to improve the boiling point of the leaching solution and the activity of H+ improves with increasing metal chloride concentration in the solution.The dissolution of silica by hydrofluoric acid and the removal of elementary sulfur with carbon disulfide were investigated.The effect of the leaching temperature,particle size,S:L ratio,stirring speed,pH,leaching time and the concentration of FeCl2 have been examined and concentration of copper in leaching solution was tested by atomic absorption spectrometry (AAS).We found that ,at the temperature of 110℃,with the S:L=1:2.8 and leaching time 4h,almost 100% of copper was removed from molybdenite concentrate .Then ,by leaching the silica and elemental sulfur from residue of copper removal ,we found that almost 100% of both elements were removed by chemical analysis.In this manner,low grade molybdenite can be purified to a content of more than 98%.

低年级的辉钼矿酸浸提纯工艺
纯度高（“98％）,二硫化钼的钼矿是一个很好的固体润滑剂,可在汽车,航空航天和军事领域.钼是最广泛使用的集中在了MoS2.Molybdenite生产通常包含诸如铜蓝（硫化铜）,黄铁矿（硫化铁）和黄铜矿（CuFeS2）一些硫化物矿物,如石英一些（SiO2）的其他杂质.钼的纯度二硫键包括一系列的精炼步骤,以生产高品位钼矿铜,硅,铁杂质concentrate.The低品位钼矿集中搬迁是非常重要的.氯化铁和氯化亚铁溶液中盐酸是一种强氧化剂lixiviant这是一种浸出如铜蓝,黄铜矿,辉铜矿铜矿产能,ect.Hydrofluoric酸是最了解它的溶解能力为市民silica.Sulfur溶于二硫化碳.在这项工作中,低品位钼矿提纯拍摄于nacid解决方案.三氯化铁被用来作为一种氧化剂,氯化亚铁加入,以提高浸出液沸点和H +活性随金属氯化物溶液中的浓度提高.由氢氟酸以及与二硫化碳脱硫硅解散国民进行了调查.该浸出温度,颗粒大小,下效果：L比值,搅拌速度,pH值,浸出时间和氯化亚铁浓度已经审查和铜浸出液浓度,原子吸收光谱法（AAS）检测.我们发现,在110℃温度的S：L为1:2.8,反应时间4小时,几乎100％来自铜钼矿集中删除然后,通过从铜浸出渣去除硅和硫元素.,我们发现,几乎100％是由这两个元素化学分析中删除.在这种方式下,辉钼矿品位低,可纯化,以超过98％的内容.
