Abstract:

A new technology of processing raw materials with the use of active alkali is suggested for bauxites of the Srednetimanskoe deposit; bauxite is opened at 300A degrees C for 1 h. This technology makes it possible to increase the recovery of alumina to 94-98\% and obtain red slimes and zeolite enriched with iron (58\%) and titanium (4.8\%); the environmental problem of storing red slimes is resolved. The blast-furnace smelting of such slimes makes it possible to obtain naturally doped cast iron and slag enriched with titanium and rare earth metals. When purifying (desiliconizing) the aluminate solution, a valuable product-sodium aluminum silicate hydrate of the zeolite type-is incidentally obtained.
