在工业矿石的浮选过程中,槽内物料的K值随时间的延长而下降,其下降规律已在“浮选速度方程”(以下简称“速度”)一文中进行过探讨。那么,在待浮物料中具有各种不同K值的量究竟占多大的比率,即K值或k值是如何分布的呢? 国内外不少学者对K值的分布问题进行过研究,具有代表性的有采用作图、筛析、拉普拉斯逆变换、最小二乘法 During the flotation process of industrial ores, the K value of the material in the bath decreases with time, and the descending law has been discussed in the paper “Flotation Velocity Equation” (hereinafter referred to as “Velocity”). So, in the material to be floated with a variety of different values ​​of K what exactly accounted for the ratio, that is, K or k value is how it is distributed? Many scholars at home and abroad to study the distribution of K values, with representatives Sexual use of mapping, sieve analysis, inverse Laplace transform, least squares method
