BacTech Environmental Corporation applies the patented BACOX bioleaching technology to the processing of toxic, arsenic-laden mine tailings. An added benefit of bioleaching, in addition to stabilizing arsenic and capturing heavy metals, is that it oxidizes sulphides in mine tailings, thereby eliminating a major source of acid mine drainage. The technology also recovers precious and base metals from tailings for sale to market. Bioleaching is an environmental clean up solution that also creates a profit. Source: www.bactechgreen.com
