REGENERATION METHOD OF METALS FROM HEAVY HYDROTREATMENT PRODUCTS Russian patent published in 2012 - IPC C22B23/00 C22B34/30 C22B34/22 B01J38/00 C10G47/02 

FIELD: metallurgy.

SUBSTANCE: method involves the following steps at which: initial material is processed into the ash containing the metals subject to regeneration, which have been chosen from the metals including vanadium, metals of group 8-10 and metals of group 6; the above ash is leached by leaching solution so that the first solid substance is obtained, which contains metals of group 8-10, solid carbonaceous material and supernatant fluid containing vanadium and metal of group 6; supernatant fluid is mixed with solution of ammonia sulphate and the deposit containing vanadium and additional fluid containing metal of group 6 is obtained; additional supernatant fluid is mixed with leaching solution, solution of ammonia sulphate and solution of sulphuric acid and the deposit containing metal of group 6 is obtained.

EFFECT: methods are effective for regeneration of metals without formation of other undesirable by-products.
