Mixture containing bibenzimidazoles and a method of zinc, iron, copper or cadmium extraction |
| abstract |
FIELD: metal extraction. SUBSTANCE: mixture has bibenzimidazoles taken separately from -R, -COR, -CH 2 COOR, -CH(COOR) 2 and -COOR or they together form the group taken from where R represents nonobligatory substituted hydrocarbil-group; A and B taken together with two carbon atoms to which they bound form nonobligatory substituted benzene ring; and C and D taken together with two carbon atoms to which they bound form nonobligatory benzene ring. At least 50 wt.-% bibenzimidazoles in indicated composition has formula where X and Y as indicated above; T, U, V and W can have similar or different values and represent H, R 1 and OR 1 at condition that at least one of members T, U, V and W represents R 1 or OR 1 ; and R 1 represents C 1-6 -alkyl. Mixture is useful for zinc extraction from aqueous zinc solution in the presence of other metals. EFFECT: increased effectiveness of mixture. 16 cl, 5 tbl |
