FIG. 1 is a schematic flowsheet of a conventional phosphate beneficiation process. FIG. 2 and 3 are schematic flowsheets showing the phosphate beneficiation process of a phosphate rock and a phosphate slime, respectively, utilizing the collector agent of the present invention.
Worldwide, most soils and crops require phosphorus (P) additions to improve fertility and production. Directly applying unprocessed phosphate rock to soil may provide a valuable source of plant nutrients in specific conditions, but growers must consider several complicating factors and limitations.

The chemical analysis of the rock revealed that P 2 O 5 = %, CaO = %, SiO 2 = % and CaO:P 2 O 5 ratio = 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.
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.

Enhanced flotation reagents for beneficiation of phosphate ores Abstract. An improved phosphate ore beneficiation process is disclosed which comprises the employment of a novel combination of surfactants which, when combined with fatty acid collectors, enhances recovery of phosphate minerals in anionic flotation, even when used in plant water.
Phosphoric acid is produced by either a dry or a wet process. In the dry process, phosphate rock is treated in an electric furnace to produce a very pure and more expensive phosphoric acid (frequently called white or furnace acid). In the wet process, the phosphate rock was treated with acid producing phosphoric acid (also called green or
