摘　　要：近年来,黄金选冶技术发展十分迅速,在常规矿石和难处理矿石选冶技术领域均实现了重大突破。文中详细论述了破碎磨矿、重选、浮选、氰化、金银精炼等工艺技术的改进与发展;同时论述了焙烧氧化、热压氧化、生物氧化和化学氧化等难选冶矿石预处理技术的现状及发展趋势。The technology of gold extraction has developed rapidly. The remarkable advances have be made in the technologies of gold from both easy-to-treating ores and refractory ores. The article describes the advances in crushing, grinding, gravity concentration, flotation, cyanidation and refining of gold and silver; It also presents recent status and prospects of pretreatment processes such as roasting, pressure oxidation, biooxidation and chemical pretreatment.
