一、概述泡沫浮选问世以来,浮选动力学一直是选矿研究的一个重要课题。早在三十年代H.G.Zuniga和提出了浮选过程的动力学方程。其中的方程表达式为dn=K(n_0-n)dt (1)积分后得ε_δ=1-e~(-kt) (2)式中n_0——浮选开始时矿浆中所含的矿粒数; n——在时间t内浮入精矿的矿粒数; t——浮选时间,分; K——浮选速度常数,分~(-1)。(2)式一般称为一级反应方程,也是至今较易被人们接受的基本方程之一。分析(2)式,知其符合指数分布函数(a>0)
First, an overview Frost flotation since the advent of flotation kinetics has been an important topic of beneficiation research. As early as the thirties H.G.Zuniga and put forward the kinetic equation of the flotation process. (2) Where n_0 - ore particles contained in the slurry at the start of flotation Number; n - ore particles floating in the concentrate within the time t; t - flotation time, minutes; K - flotation velocity constant, points ~ (-1). (2) is generally called the first-order reaction equation, which is one of the basic equations that has been accepted by people so far. Analysis (2), we know that it is in line with the exponential distribution function (a> 0)
