The drier the rock is (one to two per cent), the more dust can be removed, often allowing air classifiers to replace water wash systems altogether. When higher surface moisture is present in stone sand (2.5 to three per cent), the fines stick to the rock and larger air classifiers are required, with more airflow than usual. Again, due to high ...

Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause …

The drier the rock is (1–2%), the more dust can be removed, often allowing air classifiers to replace water wash systems altogether. When higher surface moisture is present in stone sand (2.5–3.0%), the fines stick to the rock and larger air classifiers are required with more airflow than usual to be effective.

To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees. Adding it to the soil surface may not be as effective. If you have a well-established lawn and trees, scatter the rock phosphate over the landscape.
