某锡铜硫化矿半自磨半工业试验研究

The Semi-Autogenously Grinding and Semi Industrialization Experiment Study on one Tin-Copper Sulfide Ores

采用1 800×610 mm自磨机对云锡大屯选矿分公司处理的锡铜硫化矿进行半自磨半工业试验研究,通过对松树脚锡铜硫化矿进行磨机台时处理量、磨机转速、磨矿浓度、钢球充填率条件试验及连续稳定试验,结果表明,锡铜硫化矿采用半自磨工艺取代传统三段一闭路碎矿工艺是可行的,磨机排矿产品中新增-0.019 mm锡石过粉碎金属率可控制在较低的范围内。

The semi -autogenously grinding and semi industrialization experiment study on Tin-Copper sulfide ore of YunTin Datun Mineral Separation Branch Company by Ф1 800 × 610ram autogcnously mill; The condition test and continuous and stable test of the hourly throughput, mill rotating speed, ore grinding concentration, filling rate of steel ball are carried out for the Songshujiao Tin-Copper sulfide ore, the results show, it is feasible that semi -autogenously grinding and semi -industrialization process can be adopted to replace the traditional three section and one closed circuit ore crushing process ; the new -0. 019mm tinstone that the over crushing metal rate of the minerals discharged from the mill can be controlled at the low range.
