When the permitting process is complete, mine construction begins, including road building to the site. In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground.
Federal officials have approved two open-pit phosphate mines in East Idaho that include environmental protections intended to prevent the type of pollution caused by past phosphate mining in the area.
History of Phosphate Fertilizer Production. Until the 1950s, fertilizer manufacturing facilities were relatively small and produced fertilizers tailored to the soil needs of area farmers, commonly within a 100-mile radius.

Jul 15, 2010· Organic phosphates are important in biochemistry and biogeochemistry or ecology. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry. At elevated temperatures in the solid state, phosphates can condense to form pyrophosphates. Phosphate mining dates back to the first hard rock deposits found in 1883.
This process is suitable for low grade phosphate ores including magmatite type apatite and sedimentary metamorphic type phosphorite ore. Reverse Flotation Process. Mainly used for the separation of phosphate and dolomite; dolomite is collected with fatty acid collector in weak alkaline medium, and the phosphorus mineral is enriched in the groove.
In the first year of mining alone, 11,000 pounds (5,000 kg) of phosphate were shipped to Australia. After World War I the interests of the Pacific Phosphate Company were acquired and the phosphate mining on Nauru was managed through a trust established between Britain, Australia and New Zealand.
