Also described a biosorbent for the removal of metals from aqueous solutions that comprises bacterial aggregates of Bacillus sp. VCHB-10 deposited as NRRL-B-30881, treated with polyethyleneimine and crosslinked with glutaraldehyde and the use of the 10 biosorbent for removing metals in their ...
Lithium is one of the important rare metals, which plays an important role in the emerging industrial fields. Comparing lithium extraction from hard rock lithium ore and brine, there are four main methods for lithium extraction from hard rock lithium ore: sulfuric acid method, lime sintering metho...

Among those known useful chelating agents, it is believed that the 8-hydroxyquinoline derivative is probably preferred because it has a high capacity for chelating more types of metals (see U.S. Pat. No. 3,886,080, Tables I-X). Further, as it has already been pointed out by Schucker,...
The invention concerns a method for the continuous or discontinuous extraction of a metal or several metals from a slag that contains the metal or a compound of the metal, in which the liquefied metal-containing slag is heated in a primary or secondary smelting unit (1). To provide an impro...
