Process Of Mining Phosphate

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,

In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco.The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion.. As of 2015, there are 10 active phosphate mines in four states: Florida, North

Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.

The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County. Today phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee and Hardee counties). The central Florida phosphate mining region covers approximately 1.3 million acres of land known as the “Bone Valley.”
