Abstract

Mining industry is growing in Finland and many new metal mines are expected to be opened in the near future. VTT has been continuously studying mining related issues including mine waters, treatment of side streams, stability of wastes, and recovery of minor species. Both experimental work and thermochemical models are important in problem solving. The mining process needs to minimize and optimize its use of water throughout the stages of its production process. In this presentation the main aim was to recover important metals from mine waste waters, but as the elements are removed from the waste solution, water recycling is enhanced. In this work the recovery of metals and other elements from mine acidic waste waters was planned using ChemSheet thermodynamic modeling software program. ChemSheet is thermodynamically rigorous computational platform based on the minimization of the Gibbs energy of multiphase and multicomponent systems. The software opens the way to a better understanding of the various stages in mine processing. One of the techniques imposed here is selective precipitation model repeated by experiments.
