PROCESSING METHOD OF TITANIC JAW Russian patent published in 2009 - IPC C22B34/12 C22B9/04 C22B3/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to non-ferrous metallurgy and can be used in titanium metallurgy, particularly for receiving of titanium jaw by magnesium-thermic reduction, particularly processing method of titanium jaw. Method includes vacuum separation, titanium jaw block extraction from apparatus and its cutting. Additionally at cutting it is separated from block a part of titanium jaw of off grade. Titanium jaw of off grade is crushed, leached by means of charging to nutsch filter with simultaneous feeding of boric acid solution and mixing by counterflow fed compressed air. Then it is washed by water at mixing by by counterflow fed compressed air, dehydrated and dried. Processes of leaching, washing and dehydration are implemented on nutsch filter at compressed air consumption equal to 500-1500 nm³ per 1 tonn of dry jaw.

EFFECT: productivity improvement of treatment method of titanium jaw of off grade and also in the reduction of expenditures for equipment and electricity.
