The most widely industrial flotation process for the treatment of phosphate ores containing carbonate as gangue minerals, especially in China, Saudi Arabia, Morocco, use strong acids, such as H3PO4 and H2SO4 as apatite depressants, and the carbonate minerals (especially calcite and dolomite) are selectively floated with the use of fatty acids as collectors at pH between 5.5 - 6.0.

The processes for the beneficiation of clays can also include grinding, flotation and drying (Norton, 1983, Murray, 2002). Iron is the main contaminant in clay and kaolin minerals. The removal of iron from kaolin is of particular importance in the paper industry, among others, where purity requirements are high.
It is difficult to obtain high-grade calcite grinder milling plant machines only through a single process. Therefore, in the actual production, it is recommended that the mine owners select qualified manufacturers for beneficiation test, and adopt a combination of multiple processes to improve the product quality of calcite.
The test results of the automated mineral identification and characterization system (AMICS), including the mineral composition, particle size distribution, dissemination state and degree of liberation of the target minerals, could be used to improve the beneficiation process. Taking the Dalucao rare earth ore located in Dechang, Sichuan Province, China (with an average content of 2.40 …
Calcium carbonate fillers In the extrusion process, the ready to extrude drybend is conveyed to the extruder hopper from where it is dosed into the heated screw/barrel system. Most high output lines have a vacuum degassing zone to remove residual moisture, volatiles and entrapped air from the crumbly melt which is then finally mixed and metered ...

According to the kinds of exchangeable cation, content and layer charge, bentonite can be divided into Na…
Just as is the case with almost ore processing and non-metal beneficiation, the concentrate fluorite is extracted by crushing, sieving, grinding, grading, flotation, filtration, drying, etc. How to realize the high-efficiency sorting of associated fluorite ore is a real problem in the fluorite beneficiation process.
Beneficiation of phosphate ores by electrostatic processes has been demonstrated by various researchers since the 1940's. Separations have been achieved by removing silica from phosphates, and with fewer examples of calcite and dolomite from phosphate. Limitations on conventional electrostatic systems include low capacity, the need for multiple stages, and operational problems caused by fines.
