Characterization of Gold Mining Waste for Carbon

It has been estimated that mining wastes such as gold and limestone mine wastes have the ability to store between 7% and 61% of CO 2 in brick products, suggesting that the mineral carbonation process using sedimentary mining waste is likely to have an economic benefit in the future [47,48].

What is biomining?

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them
