This invention relates to an ore dressing process. The coarse concentrates obtained from grinding selection of raw minerals are graded, then the coarse grains are sent back to the mill for regrinding, and the fine grains are dressed to obtain qualified concentrates. As the coarse grains are reground, the selective grinding process is realized due to the increment of the content of useful minerals in the mill, and the stage dressing technology in a single stage mill by regrinding the coarse concentrates can be completed. |
