甘肃某超大型金矿选矿试验研究

甘肃是西秦岭地区金矿床的主要集中区,新近又发现了一超大型金矿床。为了更好地利用该金矿资源,进行了详细地选矿试验研究。针对原矿中矿物种类复杂(金属矿物较少,非金属矿物含量较大)、嵌布粒度细小且不均匀的特性,通过全泥氰化法提金的工艺流程,获得了金浸出率85.13%的良好指标,因此推荐该方法作为矿床矿石的选矿工艺方法。

Experiment Study on a Super-large Gold Deposit in Gansu

Gansu is the mainly region where the gold deposits occur densely in western Qinling, Where has newly discovered a super-large gold deposit. In order to exploit the gold resources, the detailed labortatory tests have been conducted. Focus on complex mineral kinds(content of the Metal minerals are less, while the non-metallic minerals are larger) and uneven disseminted mineralogical characteristics of the ore, using the method of whole mud cyanide leaching to extract of gold , getting a good index of gold leaching rate of 85.13%, while failed to reach a higher index because of the impact of large inclusions of gold content. This paper recommends this process to carry out mineral processing.
