一、概况发浆法(即活性炭吸附金氰络合物)工艺,是国外提金企业应用较广的先进技术,是对整个黄金工业的发展产生根本影响的革新,它适用于处理低品位含金氧化矿石,尤其适于处理含粘土质多、难于沉降和过滤的含金氧化矿石。最早采用活性炭提金的大规模试验,是60年代中期在南非进行的,随后,美国国立冶金研究所研制了“炭浆法”工艺1973年在美国霍姆斯特克建成世界第一座大型炭浆法提金厂,首先使炭浆法获得了工业应用;由于金价的不断上涨和炭浆工艺的不断完善,促使世界范围内大批炭浆厂的建立,其中美国、南非、澳大利亚最 First, the overview hair slurry method (that is, activated carbon adsorption of cyanide complex) process, the foreign gold enterprises more widely used advanced technology, is the development of the entire gold industry have a fundamental impact on innovation, it is suitable for handling low-grade Gold oxide ore is especially suitable for the treatment of gold-bearing oxidized ores which are clay-rich, difficult to subside and filter. The earliest large-scale experiments using activated carbon to extract gold was carried out in South Africa in the mid-1960s. Subsequently, the National Institute of Metallurgy developed a “carbon slurry” process. In 1973, Holststed built the world’s first large-scale charcoal Slurry method to mention the gold factory, first of all the carbon slurry obtained industrial applications; due to the rising price of gold and carbon technology continues to improve, prompting the establishment of a large number of world-class pulp mills, including the United States, South Africa, Australia most
