Chemistry: metals Flashcards | Quizlet

In bioleaching, bacteria feed on low-grade metal ores. By a combination of biological and chemical processes, we can get a solution of copper ions (called a "leachate") from waste copper ore. Once again, we can use scrap iron and electrolysis to extract the copper from the leachate. 20% of copper comes from bioleaching - likely to increase as copper-rich ores run out.
