2021-4-30 For gold mines where the gold is unevenly distributed in coarse and fine grains, mercury plates are usually placed in the grinding and classification circuit before flotation or re-selection equipment is used to pre-recover particulate gold. The above two processes are mostly used in gold concentrators.
