一前言堆浸法提取黄金是近十年来发展起来的先进工艺,其特点是:基建投资少、生产费用低、流程简单、操作方便、规模可大可小(几百吨至几十万吨均可),它适于处理低品位(1—3g/T)或是品位虽然较高,但矿体储量小,不宜常规方法处理的金矿石。特别是最近几年来从含金料液中用炭浆法提取黄金有很大的发展,它和堆浸法配合,可以成为一个完整的湿法工艺,因此,堆浸法提金是对现代采金工业发展有重大影响的崭新工艺,它将是今后中小型金矿回收金的主要方法之一。
Preface The heap leaching of gold is an advanced process developed in the last ten years. It is characterized by less capital investment, low production cost, simple process, easy operation and large scale (hundreds to hundreds of thousands of tons It is suitable for processing low grade (1-3g / T) or high grade, but the ore reserves are small, should not be treated by conventional methods of gold ore. Especially in recent years from the gold-containing liquid extraction of gold with carbon slurry has great development, and heap leaching method, it can become a complete wet process, therefore, heap leaching gold extraction is a modern Gold industry has a significant impact on the development of new technology, it will be the future recovery of small and medium gold mine one of the main methods.
