BacTech is currently focusing on a stockpile of arsenopyrite – arsenic, iron, gold and sulphur – at Snow Lake, Manitoba. Orr says BacTech approached the government of Manitoba with the offer of stabilizing the arsenic in the tailings free of charge, if they would be allowed to keep any gold recovered in the process.
reduce gold recovery costs. This process has literally made many mines by taking low grade geological resources and transforming them to the proven ore category. Ore grades as low as 0.01 oz Au per ton have been economically processed by heap leaching. Heap leaching involves placing crushed or run of mine ore in a pile built upon an impervious …
This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.
