Gold mines often contain a lot of valuable associated minerals, such as iron, silver and copper. When processing gold ore, it is necessary to not only improve the grade of gold rock, but also comprehensively recycle other by-products. However, sometimes the gold ore tailings still contain a relatively low amount of gold after sorting.
