    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.

  • Mineral Resource of the Month: Phosphate Rock EARTH Magazine

    As a mineral resource, phosphate rock is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.

    11.21 Phosphate Rock Processing US EPA

    11.21 Phosphate Rock Processing 11.21.1 Process Description15 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding. The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. The

  • Phosphate Mineral Group Mineral Processing Metallurgy

    A somewhat different type of phosphate bearing sedimentary beds is found in Montana, which supply the large fertilizer plants in British Columbia. Formerly, there was a prosperous phosphate industry in eastern Ontario and western Quebec but, the more easily mined sedimentary phosphate drove the Canadian mineral out of the market.

  • 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 main

  • 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

  • Processing The Phosphate Risk

    At the processing plant, the slurry mixture goes through a twostep 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. The average operation can wash and size a maximum of 375 tons of pebbles in an hour.

  • Byproducts The Phosphate Risk

    In Florida, the phosphate rock is sent to processing plants in which it undergoes "wet process" to convert it into phosphoric acid. In the process, sulfuric acid is added to the phosphate to create phosphoric acid which is easily absorbed by plants. Phosphogypsum (or gypsum), a radioactive material, is a byproduct of this process.

  • Phosphate minerals

    Phosphate rock has high concentration of phosphate minerals, most commonly of the apatite group. It is the major resource mined to produce phosphate fertilizers for the agriculture sector. Phosphate is also used in animal feed supplements, food preservatives, anticorrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy.
