Abstract
The authors have analyzed copper adsorption at manganese ore from Porozhinsky province. The results allow a hypothesis on the mechanisms of adsorption kinetics: adsorption rate is limited both by diffusion processes and by chemical interaction. The analysis of adsorption isotherm and its mathematical processing show that copper exhibits strong affinity toward manganese ore surface; the Langmuir equation describes the copper adsorption equilibrium with high correlation factor. The Gibbs energy has negative value.
