Phosphorous is an undesired element present in iron ore used in the steel making process. It leads to an increase in overall production cost as well as deteriorated steel quality. The desired phosphorus content in iron ores used in steel making is < 0.1%. Numerous beneficiation studies are mentioned in the literature; however, there is no commercial scale technology …

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of …

Phosphate flotation using mixed collectors has been proved to give greater selectivity and high recovery of apatite comparing with fatty acids, which require selective depressant to be effective.

Overview of the Groveland Mine iron ore beneficiation process, utilizing direct flotation in acidic conditions (based on Houot 1983). …

This study addressed the processing of fine tailings (slimes) from a phosphate ore concentrator via flotation, despite the traditional view that ultrafine particles do not float. Phosphate flotation performances in the presence and absence of nanobubbles (NBs) in both mechanical and column cells were compared according to the metallurgical ...

Phosphate ore refinement is achieved by beneficiation processes, which depend on the characteristics of the treated ore (e.g., gangue minerals, particles size, hardness, etc.). Comminution and size separation, mineral …

3.4 Phosphate Reverse Flotation with Guar Gum. Phosphate rock is an important mineral used for producing phosphoric acid. Main gangue minerals in phosphate ores include clays, silica, dolomite, calcite, iron oxides, etc. Fine clays such as montmorillonite, palygorskite, and kaolinite are present in many types of sedimentary phosphate.

Today, more than two-thirds of the phosphate ore produced in Florida and more than half of the world's marketable phosphate is upgraded by the flotation method. Other beneficiation methods (e.g. calcinations, acid leaching, and magnetic separation) applied in the industry have certain limitations and disadvantages when compared to flotation.

In contrast, reverse flotation uses cationic and anionic collectors for silicates and carbonates, depressants, and a pH modifier between 4 and 6. According to the results of several studies on the flotation of phosphate ores, reverse flotation can be used as a unique process for sedimentary phosphate ore (Abdel-Khalek, 2000; Boujlel et al., 2019).
