Florida Phosphate Mining History
Digging the phosphate out of the ground is only one step of the mining process. Phosphate comes out of the ground as part of a matrix, which is a mix of the phosphate, sand and clay. The phosphate must be separated from the sand and clay it has melded with in the ground over millions of years.

Phosphate Rock Beneficiation Process
The phosphate ore processing can be divided into three stages: crushing—separation—concentrate dehydration. 1. Ore crushing process includes crushing, screening, grinding and grading processes. Use crushers and ball mills to reduce ore particle size to dissociate phosphorus minerals from impurity mineral monomers.
Pros and Cons of Phosphate Mining | Ablison
Alternatives to Phosphate Mining. One potential solution that has gained traction in recent years is the implementation of a few small-scale, community-driven phosphate recycling initiatives. These initiatives aim to reduce the need for phosphate mining by reusing and repurposing existing sources of phosphate.

How Has Phosphate Mining in Nauru Led to an Environmental
Most of the phosphate in Nauru has been extracted through strip mining, which is the removal of large layers of earth in order to reach the minerals underneath. This practice leaves the earth largely barren, infertile, and unable to sustain plant life. Currently, about 90% of the island is covered in jagged and exposed heaps of petrified coral ...

Phosphate | Florida Department of Environmental Protection
Nine phosphate mines are currently active. Nine mines are 100 percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down. Phosphate mines typically range in size from approximately 5,000 to 100,000 acres. Phosphate mining disturbs between 3,000 to 6,000 acres annually in Florida.

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.
