After scrubbing, the resulting pulp was wet-sieved (AFNOR sieves, see Section 2.2.2) to obtain the 71–315 µm fraction and then subjected to attrition in order to remove further clay coatings from phosphate grains. An attrition step was conducted in a Denver cell at 60% solid/liquid ratio, respectively, and 1500 rpm (5, 10 and 15 min).

attrition cells for phosphate ore

Jan 01, 2016 After extraction, raw phosphate requires several stages of treatments to become concentrated: crushing, grinding, scrubbing, sizing, attrition, de-sliming and flotation. The coarse reject, generated from the first step of ore processing, constitutes the main pollution source in the mining area around the washing plant.

Mining and Beneficiation – Phosphate Research Network

To concentrate phosphate rock in apatite (BPL or P2O5 content) we have to separate impurities from apatite using a beneficiation process. The beneficiation process could include a large variety of operations depending on the rock impurities content, the particles size and their hardness. The main operations are: classification, electrostatic separation, magnetic separation, crushing, grinding, dry enrichment, cyclonning and calcination and wet processes like chemical leaching

Reducing phosphate in your diet - Churchill Hospital

Phosphate levels in the blood can increase when the kidneys are not working properly. We measure phosphate by taking a small amount of blood when we measure your kidney function. Target phosphate levels are: • 0.9 to 1.5mmol/L for someone with chronic kidney disease • 1.1 to 1.7mmol/L for someone on haemodialysis or peritoneal dialysis. The set targets may vary for different people. Your ...

Attrition Scrubbers - 911Metallurgist

Attrition Scrubber. The attrition scrubber constructed at the M.I.T. Engineering Laboratory is an agitator, with a rotor and a stator which almost fill the space where the pulp is confined. The space between the rotor and stator is small, but it is several times the diameter of the largest grain to be scrubbed, so that no grinding takes place, but a severity of agitation sufficient to rub off the coating on mineral grains

Rotary Dryers: The Ideal Choice in Processing Phosphates

Drying Phosphate Rock. Beneficiation of phosphate rock differs greatly from one deposit to the next, with common methods including screening, grinding, flotation, classification, filtration, and more. In general, however, they are all processed via a wet process, resulting in a wet phosphate rock, which must be dried before it can move on to subsequent processing.
