湖北某地金红石选矿新工艺试验

Experimental Study on New Mineral Processing Technology of Rutile Orein Hubei Province

根据湖北某地粗粒嵌布的金红石矿的性质特点,在工艺矿物学和详细条件试验研究的基础上,制定了一种新的选矿工艺流程(磁选-脱泥-浮选),先对矿石磁选抛尾,脱泥后进行浮选,再对浮选精矿进行除杂处理,最终获得高品质的金红石精矿,其品位在90%以上,回收率70%以上,显示出该工艺流程的合理性及先进性,对同类矿石具有一定的参考价值。

According to the characteristics of the coarseness rutile in Hubei Province,on the basis of mineral processing and detailed condition test,anew mineral processing technology of magnetic separation-desliming-flotation for rutileore was determined. Firstly,magnetic separation and discarding the tailings of the ore,selection of desliming with the ore,flotation of the remainder. and removing the impurities of flotation concentrates were carried on. Finally the high quality rutile concentrates with the grade over 90% and the recovery rate more than 70% was obtained,which shows that the new process technology has the superiority and can provide reference for this kind of ore.
