Phosphate Mining

The Mining Process. Strip mining for phosphate rock violently transforms the environment, irreparably changing the character of the natural landscape. In many cases mines displace plants and animals and eat up thousands of acres of valuable habitat that are impossible to restore to their natural state. In Florida habitat loss is a significant

Ssp manufacturing

The phosphate rock mixture is passed through a hammer mill which reduces the particle size to 0.5cm or less. The coarsely ground rock is then passed through an air swept roller mill (Bradley Mill) to attain a rock grist of 7. Step 2 - Superphosphate manufacture The ground rock and sulfuric acid are reacted in a horizontal mixer.
