摘要:
广西某地硫铁矿石属难处理的叶蜡石型低品位硫铁矿,矿石中的黄铁矿原生粒度整体微细,与粘土矿物混杂相嵌,嵌布关系复杂.基于矿石特性,开发出“强化分散选择性抑制-全粒级浮选”浮硫新技术,使易浮叶蜡石粘土得到有效分散及选择性抑制、同时强化了微细粒黄铁矿的捕收效果,从而实现了该类硫铁矿中获得高品级硫精矿产品的重大突破,工业应用前景广阔.

Abstract:
A Pyrite ore in Guangxi province is a refractory pyrophyllite-type low-grade one,and the primary grain size of pyrite in the ore is small,which is mixed with clay minerals.Based on the characteristics of ores,a new technique of "enhanced decentralized selective inhibition-full-grain flotation" was developed,the easy floating pyrophyllite clay can be effectively selectively suppressed,and the collection effect of fine grained pyrite is strengthened,so that the breakthrough of obtaining high grade sulfur concentrate products in this kind of pyrite is realized,and the industrial application prospect is broad.
