从矿泥中回收锡石和黑钨矿是稀有金属选矿最困难的裸题之一。几年来在伊乌耳亭选矿厂为调整选别矿泥的捷依斯捷尔-普拉特型摇床采取了以下许多措施,如来复条之间的距离从25增加到40—60毫米;冲次从260增加到300次/分;冲程从18减小到12毫米;仔细调整床面横向和纵向的倾角以及加宽床面50％。这些措施只能使 The recovery of cassiterite and wolframite from slime is one of the most difficult nuances in the mineral processing of rare metals. For several years, the following measures have been taken by the Iuurinting beneficiation plant to adjust the Sijis-Pratt-type shaker slime, for example, the distance between slivers increases from 25 to 40-60 mm; The stroke was increased from 260 to 300 beats / min; the stroke was reduced from 18 to 12 millimeters; the lateral and longitudinal inclination of the bed was carefully adjusted and the bed width was increased by 50%. These measures can only make
