It is around $12.00 per gram. (1) Common uses: Abrasive minerals are commonly used for polishing, and cleaning of materials like metal, wood, and plastic. Many tools that you have probably used in the past are made from abrasive minerals. An example of a tool made from an abrasive mineral is sandpaper.
To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of low-grade deposits become necessary. More powerful and larger mills, higher ball charges and demanding ambient conditions call for a strong partner for grinding solutions.

The authors have proposed the concept of seafloor mineral processing for SMS mining, where valuable minerals contained in SMS ores are separated on seafloor. To apply a ball mill to the grinding unit for seafloor mineral processing, grinding experiments were carried out using a small-scale ball mill applicable to high-pressure condition.
In 1992, it established a facility to conduct trials for customer material for grinding and conveying needs. The facility is an industrial grade facility to simulate the production trials for the given customer application and material. In 2014, the company became a subsidiary of Sudarshan Chemical Industries.
