前言自19世纪末研制出氰化浸出-锌置换法以来,湿法冶金已成为处理金和银矿石的主要工艺。直至目前,氰化法仍是处理原生矿石和精矿最重要而最普遍使用的一种方法。该方法简便有效,费用又低、所以在20世纪以来头60—70年间,该工业部门工艺上很少变化与革新。 Preface Since the late 19th century developed cyanide leaching - zinc replacement method, hydrometallurgy has become the main process gold and silver ore processing. Until now, cyanidation was still the most important and most commonly used method of handling primary ores and concentrates. The method is simple and effective and low in cost, so that in the first 60 to 70 years of the 20th century, there has been little change and innovation in this industrial sector.
