针对江西含锂瓷石中富锂的特点,为实现资源高效开发利用,开展了针对性回收工艺试验研究.结果表明,江西某含锂瓷石矿原矿中Li2O平均含量(质量分数,下同)为0.35%,含锂矿物为含锂白云母和锂云母.使用组合捕收剂对该矿进行闭路浮选试验,采用"1粗2精2扫"选矿工艺流程,可获得Li2O含量为1.60%、Li2O回收率为77.37%的精矿产品.再采用高梯度磁选对浮选精矿进一步精选,可获得Li2O含量为2.01%的云母精矿.本研究可为该地区含锂瓷石中含锂云母的回收利用提供借鉴.
Experimental Study on Beneficiation of a Lithium-Containing Porcelain Ore in Jiangxi
Considering the abundant lithium content found in Jiangxi Province's lithium-bearing porcelain ore,an experimental investigation was conducted to achieve efficient resource exploitation and utilization through a recovery process.The study of process mineralogy reveals that the lithium ore extracted from a ceramics mine in Jiangxi Province contains an average Li2O content of 0.35%,with the presence of lithium-bearing minerals such as lithium-bearing muscovite and lepidolite.The closed flotation experiment of the ore was carried out by using the combined collector,and the concentrate with Li2O content of 1.60%and Li2O recovery of 77.37%was obtained by using the beneficiation process of"one time of roughing-two times of cleaning-two times of scavenging".Furthermore,high gradient magnetic separation can be employed to obtain mica concentrate with a Li2O content of 2.01%.This study offers valuable insights into the recovery and utilization of lithium-bearing porcelain ore in this region.
