摘要
河南金矿石中普遍含有黄铁矿,金与黄铁矿共生密切,是金的载体矿物。但矿石中黄铁矿含量变化大、金与黄铁矿嵌布关系复杂,给金硫解离、分选带来许多困难。文中就全省含金黄铁矿石特点、矿石分类和选矿方法进行分析。
Being carrier minerals, the gold ores from Henan Province contain pyrite universally, in which the gold is closely associated with pyrite. Such gold ores as present quite different pyrite content respctively bring about a lot of difficulties for the liberation of gold from pyrite. This paper makes an analysis of the characteristics, classification and method of ore beneficiation for this tyPe gold ore.
