多种精矿产品理论回收率计算,按传统的计算方法比较复杂,为此,我们在实际生产和计算中探索用矩阵式简化运算,使计算快速准确。(一)产率及回收率的矩阵解法用矩阵简化产率的计算,首先命α_i为原料中i组分的含量(%);β_(ij)为i组分在j产品中的含量(%),Y为原料重量,X为产品重量,γ_j为产品产率,γ_i=X_j/Y。各产品中的i组分(i=1、2、3…)之和=原料中i组分量。即β_(1Ⅰ)X_Ⅰ+β_(1Ⅱ)XⅡ+…Q_1X_N=α_1Y β_(2Ⅰ)X_Ⅰ+β_(2Ⅱ)XⅡ+…Q_2X_N=α_2Y ……………………β_(NⅠ)X_Ⅰ+β_(NⅡ)XⅡ+…Q_NX_N=α_NY因为γ_j=X_j/Y,所以(1)式化为
Theoretical calculation of the recovery of a variety of concentrate products, according to the traditional calculation method is more complex, therefore, we in the actual production and calculation to explore the use of matrix-simplified computing, the calculation is fast and accurate. (A) matrix solution of yield and recovery matrix to simplify the calculation of yield, the first order life i_i i component content (%); β_ (ij) i component in the j product content (% ), Y is the weight of the raw material, X is the product weight, γ_j is the product yield, γ_i = X_j / Y. The sum of i components (i = 1, 2, 3 ...) in each product = the amount of i component in the feedstock. That is, β_ (1I) X_I + β_ (1Ⅱ) XII + ... Q_1X_N = α_1Y β_ (2I) X_I + β_ (2Ⅱ) XII + ... Q_2X_N = α_2Y ................ β_ (NⅠ) X_Ⅰ + β_ ) XII + ... Q_NX_N = α_NY Since γ_j = X_j / Y, (1) is
