Advantages of bioheapleaching

Bioheapleaching has been chosen as the preferred technology for the Talvivaara project based on its favourable capital and operational cost profile, favourable environmental profile compared to smelting and the good performance data obtained with the technology in several trials with the Talvivaara ore.  

Bioheapleaching is a low cost process requiring only air, water and microbes to work.  It also has lower capex and opex than traditional smelting and refining processes and it is a cleaner and more environmentally friendly process.
