process for the extraction of minerals and simultaneous dehydration of mined fractions less than 50? m using ballasted flocculation

摘要

the focus is exclusively on fractions sub 50µm rom, originating from existing mineral recovery processes, such as flotation, magnetic separation and gravity concentration or for the reprocessing of tailings dams and stocks. the proposed solution is divided into three (3) distinct and simultaneous steps, as follows: step 1. separate and treat the sub 50µm fractions separately step 2. mineral recovery using selective flocculation, magnetite as ballast and polymers mixed in a magnetic field to form large stable flakes of the target mineral step 2.1 treatment of mineral flakes step 3. flocculation of silicates and other gangue minerals using magnetite as ballast and polymers mixed in a magnetic field to form large stable flakes step 3.1 treatment of mineral gangue flakes is a focused process with the objective of simultaneously concentrating the minerals and providing a stable, transportable and low-grade solid waste with the process waste, the water resulting from the quality process is returned to the front of the process. it is a double continuous process completely controlled by scada. It is important to note two important factors: 1. what is described here is a dual industrial and non-laboratory process 2. no claims are made for any specific equipment. on the contrary, the described process means combining existing equipment in an innovative way, in order to achieve the prescribed objectives. less total chemical addition and better water return are positive environmental aspects. the process complements the existing metallurgical concentration processes.
