ADSORPTION LOSSES IN AMMONIA LEACHING OF COPPER, NICKEL

In ammonia leaching cobalt extraction generally does not exceed 50%, whereas copper and nickel recoveries in excess of 85% are achieved. Since manganese nodules possess high specific surface areas, the poor cobalt recovery may be related to the presence of finely divided leach residues. Adsorption experiments have been conducted to investigate the of pH. The

Synergistic effect of floatable hydroxyapatite modified

The high adsorption capacity of HBC toward soluble Cd in soil pore water would reduce the risk of residual soluble Cd in soil pore water to rice planting caused by inefficient drainage in the field. And the released Ca 2+ from hydroxyapatite could further serve as the leaching agent to activate the Cd in soil via cation exchange with Cd ( Makino et al., 2007b ; Zhou et al., 2021 ).
