"The current sampling systems of ore flows or concentrates are based on the method of cross sections in point sampling and the method of scooping in reducing. The limited number of point samples in sampling and microsamples in reducing lead to big random and probable systematic errors. The paper defines the principles of sampling, …

Dry beneficiation is generally used to process bentonite with better raw ore quality, or bentonite-rich ore with montmorillonite content of more than 80%.This method is to dry the raw ore in the sun, air dry it naturally or dry it in the oven. It is first crushed manually or with a jaw crusher, and then crushed with a Raymond mill and other roll …
