发明名称 METHOD OF SEPARATING MINERAL PARTICLES WITH PRETREATMENT WITH MAGNETIC COLLOID
摘要 FIELD: chemistry.SUBSTANCE: method involves mixing aqueous pulp of starting material with a dispersion containing colloidal magnetic particles and treating the obtained mixture in a magnetic field to extract a concentrate of the valuable component. The dispersion of magnetic particles is pre-stabilised by treatment in an aqueous medium with reagents of general formula A1-R-A2, where R is a hydrocarbon radical selected from C-C, A1 is COOH or CONOH, A2 is OH or CH(OH), or treatment in a liquid hydrocarbon medium with reagents of general formula A1-R, where R is a hydrocarbon radical selected from C-C, A1 is COOH or CONOH. After stabilisation, the dispersion is treated with a functionalising agent and mixed with the pulp of the starting material. Extraction of the concentrate of the valuable component and magnetic particles is carried out by deposition in a gravitational field in form of magnetic floccules with field strength of 80-880 KA/m or on magnetic separators in form of magnetic floccules with field strength of 32-800 KA/m.EFFECT: high efficiency of extracting fine mineral particles using a technique for magnetisation with a magnetic colloid, followed by separation of the valuable component using magnetic techniques.8 cl, 4 tbl, 5 ex
