当前,在选矿技术和综合利用程度不断提高的情况下,精矿品种越来越多,因此选矿理论回收率计算方法的应用也就更为广泛。关于单一精矿产品选矿理论回收率的速算问题,《有色金属》(选冶部分),1974年2期及11期已先后发表了使用计算尺速算法。但是,两种和两种以上精矿产品理论回收率的计算方法却是复杂的,大有简化的必要。 At present, with the increasing of beneficiation technology and comprehensive utilization, more and more concentrate varieties are used, so the application of theoretical calculation of ore dressing recovery rate is more extensive. On the single concentrate product beneficiation theory recovery rate calculation problem, “Nonferrous Metals” (Department of Metallurgy), 1974 2 and 11 have published using the calculation of the speed algorithm. However, the calculation of the theoretical recovery of two or more concentrate products is complex and greatly simplified.
