METHOD FOR INTEGRATED PROCESSING OF PYRITE CINDERS AND PROCESS LINE FOR REALIZATION THEREOF Russian patent published in 2003 - IPC

FIELD: sulfuric acid production ecology. SUBSTANCE: invention relates to processing of environmentally harmful sulfuric acid production waste, in particular to reusing pyrite cinders. Integrated processing consists in crushing pyrite cinders followed by separation. The former is accomplished in at least two steps: pyrite cinders are first subjected to primary grinding and then ground particles are disintegrated into colloid state. Resulting material is further activated and separated electrophoretically into components. Process line comprises mill, into which starting material is charged, disintegrator, into which primarily ground material is charged and converted into colloid state, and also electrophoreticseparation apparatus receiving material from disintegrator. EFFECT: simplified production, reduced production cost, and improved environmental condition. 2 cl, 1 dwg
