The establishment of grinding kinetics equation of Au-Cu ore from Zijinshan
Translated Abstract
Au-Cu ore from Zijinshan,Fujian was crushed by high pressure grinding rolls(HPGR)and jaw crusher(JC),and batch grinding test of the crushed product from different crushing processes was carried out.The grinding Kinetics equation of the crushed product from different crushing processes was more accurately established by curve fitting method used MATLAB7.1.The results showed that,all correlation coefficients(R 2)of the best fitting function are greater than the correlation coefficients of the exponential fitting function when curve fitting for grinding kinetic parameters k(d)and m(d)using MATLAB7.1,so the fitting effect of the best fitting function are better than the exponential fitting function.Grinding kinetics equation established by the best fitting function when curve fitting for grinding kinetic parameters k(d)and m(d)is more accurate than that by the exponential fitting function.
