Chemical Processing of Phosphate

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.

Reducing the P-Cycle by Grinding | ACS Central Science

Grinding the polyphosphate/hydride mixture in a ball mill is the key to achieving a high yield of phosphite. The friction and impact generated during milling promote the reaction between solid polyphosphates and potassium hydride at room temperature that produces phosphite with good selectivity.

Grinding aids for dry fine grinding processes

In contrast to that, Deckers and Stettner [78] revealed that the grinding ball size as well as the ball filling ratio influence the grinding aid effects. A further hint regarding the change of friction and stress conditions as a consequence of the grinding aid application is given by the results of Moothedath and Ahluwalia [59]. They operated a ...
