There are several major factors that affect gold ore processing. Of which, gold grade, mineralogy and metallurgy are the three major ones. Technically, gold is commonly extracted from various ores using gravity, flotation, cyanidation or a combination of these processes. For refractory gold ore processing, pre-treatment technologies such as fine-grinding, autoclaving, roasting and bio ...
