一、概述当沸腾焙烧发展后,显示出其独有的特点,热效应很高,有可能进行含硫甚低的矿石的自热焙烧,根据国外资料,可焙烧含硫12%的矿石,捷克斯洛伐克在生产中已用含硫9.5～10%的矿石自热焙烧。降低矿石中的含硫要求,可省去选矿过程,并使有价成份的利用程度大大提高。另一目的是解决某矿铜尾砂的综合利用的问题,某矿的选矿流程是选铜以后的铜尾砂先进行粗选,而后进行精选才得到含硫较高的磁硫铁矿,选矿硫的总
First, an overview When the development of boiling roasting, showing its unique characteristics, high thermal effects, the possibility of very low sulfur ore roasting, according to foreign sources, calcination of 12% sulfur ore, Czechoslovakia In the production of sulfur has been used 9.5 ~ 10% of the ore self-roasting. Reduce the sulfur in the ore requirements, can save the beneficiation process, and make the use of valuable ingredients greatly increased. Another purpose is to solve the comprehensive utilization of a mine copper tailings problems, a mine beneficiation process is copper copper tailings after the first rough selection, and then selected to get high sulfur magnetic pyrite, beneficiation Total sulfur
