【摘要】 一种储量巨大的典型细粒难选贫锰矿,经历了长时间的重选、浮选、强磁选及焙烧磁选的研究均难于回收。而用连二硫酸法处理虽能得到很好的指标,但成本高。从矿物结构找到其难选的真正原因,发展了一种“自磨解洗——剪切洗矿——超声波分散高梯度磁选”新工艺。本文重点研究了用于细粒的剪切洗矿。更多还原

【Abstract】 It has been proved that the separation of a typical manganese ore is very difficult,which isabundant in reserves,fine in size,refractory in processing and low in rade,through many years′research with conventional separation techniques.By means of the nalysis of this ore structure,wehave found the reason which causes the separating ifficulty.Based on this an innovative teehnique ofautogenous desintegrating washing——shear ashing——ultrasonic dispersion high-gradient magneticseparation has been developed.This paper ocuses on the shear washing used for the fine particlesseparation of manganese ore.更多还原
