引言随着难选金矿矿床发现数量不断增多,一些采矿公司正在加速发展选矿技术以使这些矿床能投入生产。在70及80年代期间,人们致力于研究不经预处理则不宜以氰化法处理的矿石,这些所谓难选矿石的预处理是通过物理方法如磨矿或化学方法如氧化作用将硫化矿物磨细(或)氧化,将包裹在硫化矿物中的金粒解离出来(最常见的这些难选金的基质是带有或不带有砷黄铁矿的黄铁矿)。矿石中含有的活性炭质组分可以与溶解
Introduction As the number of refractory gold deposits is on the rise, some mining companies are accelerating the development of their beneficiation technologies to bring these deposits into production. During the 1970s and 1980s, efforts were made to study ores not suitable for cyanidation without pretreatment. Pretreatment of these so-called refractory ores was carried out by physical methods such as grinding or chemical methods such as oxidation Finely or oxidatively dissociate the gold particles encased in sulphide minerals (the most common of these refractory gold substrates is pyrite with or without arsenopyrite). Ore contained in the activated carbonaceous components can be dissolved
