Process for Manufacture of High Grade Synthetic
Rutile
Description
The process aimed at increasing the
TiO2 content by (1) high temperature reduction of ilmenite
with coal in a rotary kiln (2) leaching of metallic
iron from reduced ilmenite route with an accelerated
corrosion process in stirred reactor.
The major advantages is the regeneration of iron. And
iron oxide without resorting to acid leaching. And acid
regeneration thus helping to overcome the problem of
acidic effluents also.
