目前,在黄金选冶工艺上出现了许多革新.它们大致可分为两类:第一类是对整个贵金属的生产有重大影响的;第二类是能够解决贵金属提取工艺中某些局部难题的方法和设备上的改革.堆浸法和活性炭吸附浸出法的出现,对采金工业的发展产生了重大影响.这些方法已在加拿大、澳大利亚,菲律宾和津巴布韦等世界各产金国家得到了广泛应用. At present, there have been many innovations in the gold metallurgy process, which can be broadly divided into two categories: the first one has a significant impact on the production of the precious metal as a whole; the second one is that it can solve some of the local problems in the precious metal extraction process Methods and equipment The heap leaching method and activated carbon adsorption leaching method have had a significant impact on the development of the gold mining industry and have been widely used in various gold producing countries such as Canada, Australia, the Philippines and Zimbabwe .
