Phytomining & Bioleaching By Lucy Patterson (Sophie's

Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. The bacterial leaching process is very slow compared to other methods. The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women
