Mineral Resource of the Month: Phosphate Rock

2015-1-28 · Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate-producing state. Currently, phosphate rock is mined in Florida, Idaho, North Carolina and Utah.

25.2 Extracting ores | Mining of mineral resources | Siyavula

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.
