An inclined trough in which crushed ore is washed with running water to flush away impurities 洗矿槽,淘汰盘一个倾斜的槽,在其中被碾压的矿石被流水冲刷以冲走杂质
At the bottom end of a soaring market , an ethnic chinese worker squats in a sluice to gather tin ore at a mine on bangka island off the sumatran coast 在苏门答腊外海邦加岛的一处矿场,一名华裔工人蹲在一个洗矿槽内采集着锡矿砂。
After checking the whole ore - washing process , and analysing the particle size and the experiment results , this paper shows the necessity and possibility of recovering the lost mn 通过对洗矿作业的查定及产品粒度组成和回收试验结果的分析,论证从溢流中回收流失的锰矿物的必要性和可能性。
Abstract : the recovery rate of mn has remained very low in daxing mnore - dressing plant since it was put into production in 1992 , due to the fact that the overflow is strong and the mn grade in it is high 文摘:广西大新锰矿选矿厂,由于其洗矿作业的溢流跑粗且含锰品位偏高,影响选矿厂锰金属回收率。
Abstract : the control methods of tailing dam of wulongquan mine were introduced , some new techniques as recovery and utilization of the wash - or e tailings of limestones and dolomites , and draining seepage and solidification technology by radial well to reinforce the main dam were described in detail 文摘:介绍了乌龙泉矿尾矿库治理的具体方法,详细地阐述了回收利用石灰石、白云石洗矿尾矿的回收利用和采用辐射井排渗固结技术加固主坝等新工艺。
Large pieces of rock are only suitable for use as road surfaces in the form of fine gravel , run - of - mine coal needs to undergo a size reduction prior to further treatment , and lumps of ore need to be crushed to small pieces because sintering plants require feed material with a high degree of fineness 公司的目标是生产破碎机和洗矿机。只有砂砾状的岩块才适合于路面,原煤必须首先要被击碎才能被加以利用,矿石必须被捣碎,这是因为烧结设备只能处理细微物料。
