Title:
METHOD AND APPARATUS FOR MANUFACTURING WATER-GRANULATED SLAG
Document Type and Number:
Japanese Patent JP2014125396
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing water-granulated slag for use as sand blasting material, without necessity for large-scale reconstruction.SOLUTION: The method for manufacturing water-granulated slag includes contacting molten slag discharged from a smelting furnace in copper smelting with granulation water so as to be water-granulated, receiving the produced water-granulated slag in a water granulation pit 6 together with granulation water, and collecting the water-granulated slag by sedimentation. Air is blown into the granulation water in the water granulation pit 6 so as to generate fine bubbles, by which fine water-granulated slag is floated and separated. The position for blowing air is within a circle A with a radius of 6 m and the center at a falling point of the granulation water in the top view of the water granulation pit 6, and preferably within the range from a depth of 0.5 m below the water surface to the bottom face.
