在电力研究院的倡议下,维姆科公司进行了浮游选煤研究。研究的目的是使浮选更有效地排除灰分(杂质)和黄铁矿硫,并保持高的可燃体回收率。在进行研究时,使用过实验室的、半工业性的和工业性的浮选机,用以确定分选工艺和操作对浮选效果的影响。 At the initiative of the Electric Power Research Institute, Wilmco conducted a study on floatation coal preparation. The purpose of the study was to make flotation more effective in removing ash (impurities) and pyrite sulfur, while maintaining high recovery of combustibles. During the study, laboratory, semi-industrial and industrial flotation machines were used to determine the effect of sorting processes and operations on flotation performance.
