A method of selectively extracting calcite and dolomite away from apatite in phosphate rock or phosphatic limestone wherein the phosphate rock or phosphatic limestone is treated with a mixture of sulfur dioxide, water, and a carbonyl compound. Solids are separated from the liquid phase. The solids consist principally of apatite admixed with clay, quartz, and other accessory minerals originally
Phosphate rock benefication . United States Patent 5221466 . Abstract: This invention provides an improved method for the rougher flotation of phosphate ore using sodium carbonate to control the pH at about 9.6-10.5. In this patent, in the separation of the phosphate values from carbonate contaminants, the carbonate is a component of the
United States Patent 4388180 . Abstract: A process is disclosed which removes gangue minerals from phosphate rock by forming an aqueous slurry of phosphate rock and its impurities, then using a low boiling, nonpolar, water insoluble, bridging hydrocarbon to selectively agglomerate the phosphates.

Apr 8, 1991 Falconbridge Limited. A process for the froth flotation separation of phosphate containing minerals by the use of a new collector agent is described. The new phosphate collector agent is
May 06, 2016 Phosphate Beneficiation. Market Specifications Bone phosphate of lime, 70 to 72 per cent, common. Bone phosphate of lime 72 to 77 per cent, premium. Production Problems. Phosphate rock being a low-priced material is produced as near the fertilizer market as possible and haulage costs determine production.
Aug 01, 2021 patents on phosphate rock benefication A Tailor Made Approach for the Beneficiation of Phosphate The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P 2 O 5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted
Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities. Steps used in beneficiation depend on the type of rock. A typical beneficiation unit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rock that is larger than 1.43 millimeters (mm) (0

Wyoming's Bentonite industry produced over 4.0 million tons of bentonite in 1999, with 644 mine and mill employees, and 240 contractor employees. Exploration for new bentonite beds is normally gifted with auger bit drilling. Once the auger drill stem reaches the soft bentonite it sinks very fast, which indicates to the driller that bentonite
Mining & Processing. Bentonite is surface mined through a process called back-casting where reclamation is performed by filling the mining pits with soils from subsequent pits while the mine is in production. Typically the topsoil layer is about 30 inches deep, which is removed using heavy equipment.
Mining and processing. Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. Bentonite production process features ore mining, sodium activation if required -, drying, and milling.
While bentonite per se is abundant on earth, careful selection of the right bentonites for the individual applications is a crucial part of ensuring uninterrupted supply. To this end our own exploration team of geologists, mineralogists and mining engineers travels the world to find suitable deposits for our customers’ needs.
