Therefore, the correct analysis of the elements is required.
The vast majority of manganese mines in China are lean mines and must be processed. However, because most manganese ores are fine-grained or fine-grained, and contain a considerable amount of high-phosphate ore, high-iron ore, and co- (associated) beneficial metals, it brings great difficulty to the processing of ore.

Here's an important note: The tumbler works like a burnisher. It won't remove scratches, nicks, or other surface imperfections. So, you'll have to get rid of those beforehand. I find that removing scratches, then polishing with white diamond, then washing the piece completely before tumbling, gets me the best results. I recommend …
