摘要:

金矿石的加工和提取很大程度上受制于金矿石的品位、储量和赋存状态。由于金在地壳中的丰度极低又具有极大的分散性,导致其在许多矿床中的分布极不均匀。同时,金赋存状态的多样性也使得金矿石(特别是难处理金矿石)的加工处理更加充满了挑战和风险。地质冶金学的目的就是通过合理而有代表性的采样使选矿试验得到的数据能真实地代表或最大限度地逼近被研究的矿床(矿石),从而将矿床(矿石)可变性造成的技术风险降到最低。

Abstract:

Mineral processing and extractive metallurgy of gold ores are largely driven by their grade,reserve and gold deportment.The concentration of gold in the crust is extremely low and highly variable,resulting ore variability in many gold deposits.More importantly,gold in a deposit may occur in two or three forms,making gold ore processing extremely challenging.The goal of gold geometallurgy is to reduce and minimize the technical risk through representative sampling and subsequent mineralogical and metallurgical testwork.It is a technique to document variability within an orebody and quantify the impact of many factors including geology and mineralogy on grinding, flotation,leaching and metal recovery processes.

Key words: gold, geometallurgy, process mineralogy, mineral processing
