 | As surface ore bodies are depleted, mines are beginning to treat the deeper sulphide ore bodies, many of which will be refractory. BacTech's technology is perfectly suited for many of these projects. Capital and operating cost advantages, together with the environmentally friendly qualities of the technology place BacTech in a position for project participation and licensing opportunities.
Bioleaching of sulphide concentrates and ores frees gold, as well as releasing base metals. Together with precious metals, many valuable base metals, including copper, nickel, zinc, cobalt and molybdenum, occur as sulphide minerals. During the bioleaching process, the base metals are released into the dilute acid and are then recoverable by conventional and new processes. The presence of significant levels of base metals in a complex refractory gold deposit can favourably influence project economics.
