METHOD FOR CONCENTRATION OF TITANIUM-SILICA CONCENTRATES Russian patent published in 2005 - IPC

FIELD: metallurgy.

SUBSTANCE: method includes melting in water-cooled crystallizer, into which at bottom a layer of non-electric-conductive source material is placed and in the center of it a channel is formed with diameter approximately equal to two electrode diameters, which is filled by current-conductive material. After that crystallizer Is connected to minus, and electrode with plus of direct current power block and electrode is lowered until touching current-conductive material until appearance of stable arc, and after start of crystallization of titanium slurry main working period is begun - accumulation of slurry block, during whole period of which periodically before end of melting portion loading of material of given compound is performed. Current-conductive material is formed by adding to source material not less than 33% of breeze coke from mass o source material.

EFFECT: lower costs, higher efficiency, broader functional capabilities.
