摘要: The reasons for decline of bioleaching efficiency Zn and Mn from spent batteries at high pulp densities were analyzed; the measures improving investigated. results showed that extraction dropped 100% 1% density to 29.9% 8% density, with 94% only 2.5%. It was almost linear reduction activity sulfur-oxidizing bacteria increase witnessed declined Zn; it complete inactivation iron-oxidizing 2% or higher dose Mn. By means reducing initial pH value leaching media, increasing concentration energy matters exogenous acid adjustment media during bioleaching, maximum 89% 4% attained, respectively.
