- Beneficiation Plant For Clay
A sample of the bauxite washing residue (BWR) was collected in the bauxite beneficiation plant of Mineração Paragominas SA, in Northern Brazil and given for this work. To produce the clinkers, the sample was mixed with commercial CaCO 3 (≥99.5% pure, from Applichem Panreac) as calcium source simulating the use of limestone.

The first rule deals with the conservation of mass. The total flow of the material into the process plant equals the total flow out. The second rule relates to the quality or grade of the concentrate product. In practice, it is impossible to produce a concentrate consisting of only one mineral. The third rule is a corollary of the second.

At the beneficiation plant the phosphate is separated from the sand and clay. After going through beneficiation, the clay slurry is pumped to a settling pond. The sand is sent back to the mine site to be used in reclamation and the phosphate is sent to the chemical processing plant where it is processed for use in fertilizer and other products.
