我国黄金矿产资源丰富,但低品位的贫矿较多。随着生产的发展,对低品位金矿的开发利用显得十分重要。目前,国外处理低品位金矿的方法主要有堆浸、全泥氰化及炭浆法等。其中最为经济的方法是堆浸法。自七十年代初在美国首先投入生产以来,世界上已有许多国家应用该法生产金、银。 China is rich in gold and mineral resources, but low-grade lean ore more. With the development of production, the development and utilization of low-grade gold deposits is very important. At present, the overseas processing of low-grade gold mine mainly heap leaching, full mud cyanide and carbon slurry method. One of the most economical methods is heap leaching. Since the United States was first put into production in the early 1970s, many countries in the world have applied this method to produce gold and silver.
