    Deposits which contain phosphate in quantity and concentration which are economic to mine as ore for their phosphate content are not particularly common. The two main sources for phosphate are guano, formed from bird droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite. As of 2006,the US is the world's leading producer and exporter of phosphate fertilizers, accounting for about 37% of world P2O5 exports.

  • Phosphate Beneficiation Process

    Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the

  • Processing The Phosphate Risk

    In Florida, after the phosphate rock is extracted, the ore is dumped into a pit at the mine site, and high-pressure water guns turn it into slurry. The slurry is pumped to a beneficiation plant. 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

  • Processing Phosphates for Use in the Fertilizer Industry
    Map & Dap Fertilizer ProductionAn Alternative Approach to Map GranulationAdditional Phosphatic FertilizersConclusionOnce phosphate rock has been mined, the actual phosphate ore is beneficiated to separate it from the unwanted materials. This is carried out via a wet process, the resulting material of which must first be dried. This is typically carried out in a rotary dryer, an industrial drying system ideal for processing phosphate ore, because of its heavy-duty build and high capacity capabilities.The dried phosphate ore is then most commonly proSee more on feeco

  • Beneficiation of Saudi phosphate ores by column flotation

    The chemical analysis of the rock revealed that P 2 O 5 = 25.1%, CaO = 52.7%, SiO 2 = 1.17% and CaO:P 2 O 5 ratio = 2.1. The main problem of this ore is its high content of calcite mineral. The separation of such calcite gangue from apatite “phosphate mineral” is the main target of this beneficiation process. Hence, column flotation

    For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced. The fertilizer market is very competitive

  • How phosphate is mined and processed

    Processing The phosphate is sent to a chemical processing plant, or fertilizer manufacturing plant. Here, molten sulfur, shipped to Florida ports and trucked to the plant, is used to create sulfuric acid. The sulfuric acid is then mixed with the phosphate to make phosphoric acid. The phosphoric acid is the main ingredient in fertilizer, but can
