Although the phosphate resources in China are abundant, they mainly consist of low-grade phosphate rock. The beneficiation of low-grade phosphate ores is also a worldwide problem, and effective technologies to process such ores are yet to be developed. As a result, most low-grade phosphate rocks are currently unexploited.

Specifically, several differences in the ore characteristics are noted The fraction of coarse particles suitable for phosphate pebble is less The P2Og content is lower The amount of MgO is greater, owing to the presence of carbonate minerals, mainly (Ca, Mg)C03 (as dolomite) and CaC03 Phosphate rock with …
To determine the leachability of phosphate rock to both alkaline leach and acid leach (Fig. 3) solutions for uranium extraction leaching efficiency and time were considered with the highest uranium extraction efficiency range of 70-80% obtained from the sulphuric acid leaching conditions. Comparatively, extraction efficiencies of 40% to 60% were
Solving Africa's ore challenges: carbonate and silica In Africa, phosphate producers are faced with the challenge of reducing the amount of carbonate, silica and magnesium present in the ore. As lower-cost, simpler-to-beneficiate ores are depleted, producers must mine and process ores that are higher in carbonate, magnesium and silica.
Marine sedimentary deposits account for 80% and igneous deposits 17% of the total world output of phosphate rock. The phosphate mineral is well crystallized and exhibits a greater floatability in the igneous deposits than the sedimentary ores. Both silicates and carbonates contribute the major gangue associated with the sedimentary ores. Although removal of silica from …

Phosphate ores which are beneficiated by the method of the subject invention are found in sedimentary deposits in central Florida. Typically, the overburden is first removed, and the phosphate-rich ores are collected by dragline mining techniques. These ores are generally referred to as apatite and carbonate-fluorapatite-containing ores.
Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P2O5), medium-grade ore (20%–30% P2O5), and low-grade ore (15%–20% P2O5). The very high-grade ore blends with medium-grade ore for direct sale. The high-grade ore is mined, crushed, and sold to various fertilizer plants.
phosphate ore removes most of the organic, carbonate, fluoride and other impurities. In initial trial two low grade Indian carbonate ores were successfully upgraded using a calcination process4. Calcination is usually carried out by heating phosphate rock along with silica in the presence of soda ash at 1250-1350°C, in rotary kiln.
Phosphate rock as it is mined in Florida contains an increasing quantity of magnesium. The magnesium is present as discrete particles of dolomite (calcium magnesium carbonate). High magnesium adversely affects both the production of phosphoric acid (lowers phosphate recovery or production rate) and acts as a diluent in the final fertilizer products.

Rock phosphate. Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops. Many of the mines that produced rock phosphate are closed, and most of the marketed rock ...

Due to the high e ciency in the removal of silicate and carbonate gangue minerals, froth otation is dominantly employed for the beneciation of phosphate ore, especially for lowgrade sedimentary phosphate rocks generally, direct otation by anionic surfactants or reverse …
phosphate rock, while the single anionic reverse flotation is preferred to beneficiate the calcareous phosphate rock. A two-step flotation process, named direct-reverse flotation (Figure 2) or double reverse flotation, is usually carried out to remove silica and carbonate gangue minerals stepwise from the calcareous-siliceous phosphate rocks [8].
Chemical dissolution of carbonate minerals (calcite and dolomite) from calcareous phosphate ores, without the calcination, using organic acids also proved to be capable of beneficiating the calcareous phosphate ores on the laboratory scale.
