瓦斯泥物料性质及选别方法的试验研究

Reseabches on the Nature of Gas Mire and its Separation Method

试验研究表明，瓦斯泥主要有用成分为铁矿物，以赤铁矿和磁铁矿的形式存在；采用单一的磁选、重选、浮选方法铁矿物均不能得到充分有效地回收，而采用联合选别流程获得了较好的指标，推荐了重选－反浮选－磁选联合选别的原则流程。

The research results of the nature of gas mire and its separation experiment show that the major valuble minerals of gas mire are iron ones which consist of hmatite and magnetite.The iron minnerals can't be recovered effectively by single magnet separation or gravity concentration or flotation.But better level can be abtained by using joint separation circuit.Therefore it is suggested in this paper that a princople circuit which includes magnet separation and reverse flotation and gravity concentration should be adopted
