摘　　要：介绍了从金精矿中提金的主要方法,包括氰化法(炭浆法、炭浸法、树脂法、生物氧化法)和非氰化法(硫脲法、硫代硫酸盐法、卤素法等)。总结了氰化法提金和非氰化法提金方法的基本原理和工艺特点。另外,本研究还对每种方法的优缺点进行分析和比较,为今后研制出既高效又清洁的提金方法提供了重要的理论依据。In this paper,we describe the main methods for extracting gold from gold concentrates,including cyanidation(replacement method,carbon pulp method,carbon leaching method,resin method,biological oxidation,and heap leaching)and non-cyanidation methods(thiourea method,thiosulfate method).This article summarizes the basic principles and characteristics of the cyanidation method and non-cyanidation method of gold extraction.This study also analyzes and compares the advantages and disadvantages of each method,which provides an important theoretical foundation for developing an efficient and clean gold extraction technique in the future.
