The image slider below shows an area from the LCMAP land cover animation comparing 1985 to 2017. In 1886, phosphate rock was discovered in this area and the dominant industry went from forestry to mining. Wetlands covered many of the mining sites in this area, and many new techniques for mining wetland areas were pioneered here.
The ore is processed at plants in Pocatello and Soda Springs into elemental phosphorus and super phosphate which is used for fertilizer. Early phosphate mines, now …
Mining impacts have occurred over an approximate 17,000-acre area within portions of Bannock, Bear Lake, Bingham, and Caribou Counties, Idaho. The Natural Resources Damage Assessment (NRDA) Mine Site Project Area contains 16 major open pit phosphate mines and two processing facilities. In 2015, the Southeast Idaho …
Tough and Robust. Designed to take what miners send without complaint. A typical mineral processing plant feed bin features an overhead grizzly comprising a series of equally spaced parallel bars for the scalping of oversize barren material from the run-of mine ore. However, bin and grizzly installations of this configuration lack throughput capacity and …
Idaho mineral production value for 2012 and prior years, as compiled by the U.S. Geological Survey, is shown in Figure 2. According to the U.S. Geological Survey's statistics, Idaho's 2011 mineral value (not including processing) was a new record in 2011 with a value of $1.324 billion (Figures 2 and 3). The much lower 2012 value of

This processing is conducted in the "washer". In all the currently operating beneficiation plants, the washer is a large structure that receives the matrix, screens it, then discharges a +1.0 mm "pebble" phosphate product and a -1.0 mm slurry of liberated clay, sand, and phosphate particles. ... The remaining phosphate mineral ...
Phosphate rock minerals provide the only significant global resources of phosphorus, which is an essential element for plant and animal nutrition. Phosphate rock is used primarily as a principal component of nitrogen-phosphorus-potassium fertilizers, but also to produce elemental phosphorus and animal feed.
