This paper gives a review of the present state of heap leaching for extracting gold at home and abroad.Heap leaching which is characterized by simplicity, easy handling, less capital cost, speediness of starting Construclion and marked benefit is a new technique to extract gold from low grade ore. In the recent years, the South Africa, USA, Canada, Australia, Soviet union and Philippiness have all popularized this technique and therefore raised their gold output rapidly.In the late 1970s, China began researching and testing on this techingue and applied it to the gold industtry with satis-factory result. In this paper,a detailed description of China's practice and development of heap leaching is also made.

本文综述了国内外堆浸提金技术现状。堆浸具有工艺简单、操作容易、投资少、上马快、效益好等特点,是低品位金矿石提金新工艺。南非、美国、加拿大、澳大利亚、苏联、菲律宾等产金国都推广应用了这项新技术,加速了这些国家的黄金产量的发展。中国从七十年代末也开始了该项技术的试验研究。目前正应用于工业生产并取得比较满意的效果。本文还对中国堆浸生产实践与今后发展方向作了详细地论述。
