活性炭作为金的有效吸附剂,近十年间已日益广泛地用在金的湿法冶金领域。活性炭吸附提金被公认为是现代提金工业的重要成就,并被誉为是近百年氰化法提金工艺的一项重大技术突破。本文除就活性炭提金的发展简史、工艺原理及国内外现状加以介绍外,并就活性炭的应用前景谈几点看法。一、发展简史早在1847年就已知活性炭有吸附贵金属的特性。至1917年止连续发表过这类论文约46篇。1880年首次用木炭从氰化金溶液中提取金,1894年又公布了从含金氰化液中用木炭吸附金的专利。1902年南非等地提金业中已使用木炭吸附金,随后活性炭于本世纪初实现工业化生产。澳大利亚金矿在1916年正式用活性炭吸附法取代锌置换法提取金。当时多数理论曾错误地认为木炭提金是简单的还原过程。1926年开始有了吸附理论的报道。1939年切普曼取得了从氰化矿浆中用活性炭提金的专利。到二次世界大 Activated carbon, as an effective adsorbent of gold, has been used increasingly extensively in the field of hydrometallurgy for the last ten years. Activated carbon adsorption gold is recognized as the modern gold extraction industry, an important achievement, and known as nearly a hundred years cyanidation gold extraction process is a major technological breakthrough. In addition to the brief history of the development of activated carbon extraction of gold, the principle of the process and the status quo at home and abroad to be introduced, and talked about the prospects for the application of activated carbon. First, a brief history of development as early as 1847 known to have activated carbon adsorption of precious metals. Until 1917, there have been about 46 such papers published continuously. Gold was first extracted from gold cyanide solution with charcoal in 1880, and gold was also adsorbed from charring cyanide liquor in 1894. 1902 South Africa and other places to mention gold industry has been using charcoal adsorption of gold, followed by activated carbon in the early century to achieve industrial production. Gold in Australia in 1916 officially activated carbon adsorption method instead of zinc extraction method to extract gold. Most theories at that time mistakenly believed that charcoal gold extraction was a simple reduction process. 1926 began with adsorption theory reports. In 1939 Chep Man obtained a patent for gold extraction from activated carbon in cyanide pulp. To the second world big
