Phosphate Ore Mining

Phosphate Mines | Earth Resources Observation and Science ...

The ore in the pit is blasted by high-pressure water jets into a milkshake-like slurry. This slurry is pumped by pipeline to a processing plant that separates the sand, clay, and phosphate ore. The phosphate ore is shipped to another plant that processes it into fertilizer. This process creates several byproducts besides fertilizer.

1. China — The country's phosphate mining production decreased in 2018 to 140 million metric tons (MT) from 144 million MT in 2017, which is likely a result of Beijing's environmental crackdown on the mining industry. There has also been speculation in the past that China's phosphate production in 2017 may have been overstated.

Mining in Idaho - Idaho State University

Most of Idaho's phosphate mining is done in eastern Idaho around Soda Springs. It is believed more than half of America's phosphate reserves are in Idaho in Bear Lake, Bingham, Bonneville, and Caribou counties. Phosphate was Idaho's second leading mineral in 1974, and was very close to silver in value.

Phosphate Mining on Nauru | EJAtlas

The phosphate mining carried out partly by Nauru, but mostly by Australian and British companies, had rendered most of the island both uninhabitable and infertile (about 80% of the surface of the island) by the 1960s, leaving everything but the coastal strip uninhabitable (Klein 2014).

Phosphate Beneficiation Process

Phosphate Ore Mining. Electrically operated drag lines strip off the overburden from the mining area and deposit the phosphate matrix around a pump pit. Here it is sluiced with streams of high pressure water to the suction of a large centrifugal pump which transports the matrix slurry to the washing plant which may be a mile or two away.

Phosphate mining involves the extraction of ores containing chemical compounds rich in substances that contain the phosphate ion. These ores vary in their composition, and different varieties of phosphate rock require different mining techniques. Processing of the mined ore follows extraction. Finally, mining sites are rehabilitated to minimize ...

Phosphate Rock - Minerals Education Coalition

During surface mining, overburden is drilled, blasted, and removed by dragline to the side of the mining area for subsequent reclamation. Small draglines, electric shovels and bulldozers recover the upper ore body. The intercalating limestone layer is then blasted and removed to expose the phosphate bed, which is loaded onto trucks.

Aurora Fossil Museum » Aurora Phosphate Mine

Three large mining machines, called draglines, excavate the remaining overburden from the mine bench down to the top of the phosphate ore and place the overburden in previously mined out areas. This process, called stripping, exposes the phosphate ore, which is then excavated by the draglines and placed on the mine bench where it is stockpiled.

Phosphate Ore | Article about Phosphate Ore by The Free ...

Phosphate ores are worked by open-pit and underground-mining methods: friable phosphorites, such as those in the Baltic republics, are worked by geotechnological methods. Various methods for concentrating phosphate ores exist, and the selection of a particular method depends on the mineral composition and the structure and texture of the ore.
