摘要
本文提出了一个简便的检验金矿的方法和还原型金矿的新概念。在拿到磨细矿石后一天内就可判断出这种矿石是易处理矿，还是难处理矿，是需要在酸性介质中处理还是需要在碱性介质中处理，以及选择多大氧化能力的氧化剂。本文建议把那些既不是氧化型金矿又不属硫化型金矿，并能消耗大量氧化剂的金矿石称还原型金矿。并认为要从还原型金矿中提金，首先要使矿石从还原型转变为氧化型。
In this paper,a simple and convenient method of examing gold ore is proposed besides a new concept of reducing type gold ore is established. By this method,a sample of ground ore can be ascertained in the short time of a day whether it is refractory,whether it is necessary to be treated in the presence of acidic medium or alkaline medium and what oxidant should be employed.This paper also suggests that the gold ore which is neither oxidative type nor sulfide type and consumes great quantity of oxidant should be named as redu cing type gold ore,To extract gold from such type gold ore,the transformation from reducing type gold ore into oxidative gold ore is the first and most important affair.
