选矿厂理论回收率计算,用于对照实际回收率,全面衡量选厂取样、化验、计量等各项工作的准确性和金属流失的程度。 目前,理论回收率的计算,按选矿设计参考资料等书介绍,对三精矿一尾矿(简称四产品)的理论回收率计算在列出四元一次联立方程式并构成行列式后,推荐采用“沙路法”(对角法)解行列式。“沙路法”解行列式虽有着易记,规律性强等优点、但计算麻烦,所用加减乘除次数较多。对于四精矿一尾矿(简称五产品)或更多精矿的理论回收率计算,书 Beneficiation plant theoretical recovery calculation, used to control the actual recovery rate, a comprehensive measure of the election plant sampling, testing, measurement and other work accuracy and the extent of metal loss. At present, the calculation of the theoretical recovery rate, according to the beneficiation design reference books and other books introduced, the three ore tailings mine (referred to as the four products) theoretical recovery in the list of quadratic equations and constitute the determinant Use the “Sand Road Law” (diagonal method) to solve the determinant. Although the solution to the “Sand Road Law” has the advantages of being easy to memorize, regularity and so on, it is troublesome to calculate. For the calculation of the theoretical recovery rate of a concentrate of four concentrates (five products) or more, the book
