The dominant flotation process currently used for processing of siliceous phosphates in Central Florida is the Crago "Double Float" process (Giesekke, 1985; Zhang et al., 1997).The simplified flotation flowsheet is given in Fig. 1.In this process, after desliming and sizing, the ore is conditioned with fatty acids and fuel oil at a pH of 9.0–9.5.
Phosphate ore washing and mud removal equipment. March.20,2024. Among chemical raw material ores, phosphate rock usually requires washing. After the phosphate rock is calcined, it becomes crisp and brittle, but a large amount of calcium and magnesium oxides are still wrapped in the mineral aggregates, hindering the hydration reaction.
The phosphate ore enrichment processes allow the gangue minerals to be separated from the economical phosphate value . Several methods are used to upgrade the low-grade phosphate ore to a marketable-grade product, such as crushing, grinding, screening, scrubbing, heavy media separation, washing, roasting, calcination, and flotation.
Liberation of phosphate from the gangue occurs during ore transport and washing. First, a low-cost product, called pebble, is recovered by screening the ore at about 16 mesh. Secondly, a low-grade product (intermediate pebble) is recovered by sizing the flotation feed at about 24 mesh.
Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and non-renewable element for fertilizer production, upon which global fertility depends.The startling limitation of phosphate rock reserves has led to a renewed …

Phosphate mining generates substantial quantities of waste rock during the extraction of sedimentary ores, leading to significant environmental concerns as these wastes accumulate …
Abdelmajid et al. (2014), investigated the uranium recovery from phosphate ore from the Uro region in Sudan [51]. Initially, the phosphate ore samples were digested with concentrated nitric acid. The phosphoric acid was produced from the resulting powder with the aid of sulfuric acid at 80 °C. 4.2. Alkaline extraction
The use of phosphorus by mankind is long established.

Gangue is removed from the phosphate ore through phosphate beneficiation, which includes screening at varying size fractions, washing, and flotation. During phosphate flotation, producers use Arkema's flotation reagents to selectively separate the desired phosphate from the gangue, focusing on maximizing phosphate grade and recovery.
