Chalcopyrite leaching: The rate controlling factors

Geochimica et Cosmochimica Acta, 2010
Abstract The processes that determine the rate of chalcopyrite leaching are central to understanding how chalcopyrite (CuFeS2) behaves under the environmentally adverse conditions of acid rock drainage. To this end the effect of the acid anion on chalcopyrite leach rates using a variety of acidic media (H2SO4, HClO4, HCl and H2SO4 with 0.25 M NaCl ...

Water-leaching rates of halides from polymers

Journal of Applied Polymer Science, 1982
Water-leaching experiments of halides from polymers were carried out in batch and continuous systems. The effects of flow rate, temperature, and salt content on the leaching kinetics were investigated. Different thermoplastic polymers were used as the salt carrier, and the release kinetics from them was established. NaCl, NaBr, and NaI were leached out
