  • In Florida, the process pictured above is known as strip-mining. Phosphate rock is extracted about 30-40 feet (or more) below the surface using machines called draglines.

  • At Ma'aden, we mine phosphate rock and process it into phosphate products, including diammonium phosphate (DAP) and monoammonium phosphate (MAP), the most widely used phosphate fertilizers in modern agriculture.

  • Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid.

  • Phosphate Beneficiation. Background. Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other.

  • Efficient phosphate production requires a complex sequence of interconnected processing operations – each stage of the process affects the next. For example, inefficiencies in mining can adversely affect phosphoric acid production and ultimately impact fertilizer quality.

  • At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles. The first stage is a concentrating process that separates the phosphate pebbles from everything else.

  • Strip mining removes 20 to 40 feet of the surface of an area to get to the phosphate. In the process, the entire environmental system, including the surface and underground water flows; topography, animals and plants are changed.

  • The Mining Process. The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits. Information like the location, size, and shape of the ore is determined to focus the mining effort.

  • Idaho's phosphate mining district is the consistent, solid performer in the state, employing 2,000 workers at several companies, including Monsanto and the J.R. Simplot Company. Since the 1970's, mining companies have had to reclaim the land.
