METHOD OF COPPER GRANULATION Russian patent published in 1997 - IPC

Abstract RU 2071981 C1

FIELD: nonferrous metallurgy. SUBSTANCE: silicon-containing copper melt is ground under water by water-air flow in deep 0.4-0.7 m from the water surface maintaining water-air flow pressure 0.1-0.25 MPa and ratio between the initial water pressure and the total water-air flow pressure increase = 1:(1-3). Ratio of water-air flow slope angle to horizon to deep of its immersion is maintained at value (+25)-(-40) angle degree/m. Method can be used for production of crystalline copper sulfate. EFFECT: improved method of copper granulation. 3 cl, 1 tbl
