近来由于金价上涨,处理低品位矿石和废石堆中的原料、尾矿坝中的尾矿引起了世界各国的普遍重视.用碳浆法从这些物料中回收金有许多优点,如设备和生产费用较低.因此,英美研究所和南非国立冶金研究所非常强调在金的领域内应当采用最先进技术.目前已经针对改进碳接触以及其它方面进行了小型实验和半工业性试验的研究.英美研究所的研究提出洗脱金和电解金的更有效方法,以及用较经济的热处理和化学方法
Tailings in tailings dams have recently gained the world’s attention due to rising gold prices, handling of raw materials in low-grade ores and waste rock piles, and there are many advantages to recovering gold from these materials using the carbon slurry process, such as equipment and production Therefore, the Anglo-American Institute and the National Institute of Metallurgy of South Africa place great emphasis on the most advanced technologies that should be applied in the field of gold.Nowadays, small and semi-industrial experiments have been conducted to improve carbon exposure and other aspects. The Institute’s research suggests more efficient ways to elute gold and gold, as well as more economical heat treatment and chemical methods
