Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides. Flotation is one of the key beneficiation methods.

Iron ore reverse flotation is used to upgrade the concentrate and remove silicates. The practice of silica reverse flotation by amine derivatives has increased dramatically as more complex ores have to be mined and higher-grade iron ore concentrates with fewer impurities are requested by the steel industry.

A process and composition are provided for the froth flotation beneficiation of iron minerals from iron ores containing silicate and phosphate minerals, comprising as collectors a combination of a primary amine and a nitrogen compound containing an anionic group selected from methylene carboxylic acid, ethylene phosphoric acid and methylene phosphonic acid.

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.

8 Only a single rougher stage is used to produce a phosphate concentrate (there are plans for including a cleaner stage). Schematic diagram of the KPO processing plant After grinding and mechanical classification, the ground ore is deslimed using cyclones. The resulting flotation feed (cyclone underflow !) is in the particle size range from about 250-300 microns to 20-25 …

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.

In the flotation process, the efficient recovery of apatite from dolomite-bearing phosphate ore for phosphate fertilizer production depends significantly on the use of high-selectivity depressants.

What is claimed is: 1. An improved process for beneficiating phosphate ore comprising washing, sizing, and beneficiating phosphate ore feed particles by anionic froth flotation, wherein the improvement comprises using as the flotation collector a fatty acid based reagent comprising a blend of alcohol ether sulfate, with petroleum sulfonate, wherein the blend comprises about …
