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
· Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing lowgrade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (offsite) Once basic processing is done, the ore is taken to a refinery where the remaining ...

· Extraction of metals from their compounds is also a reduction process. Besides using carbon (coke) to reduce metal oxides to metals, sometimes displacement reactions can also be used. The highly reactive metals such as sodium, calcium, aluminum, etc. are used as reducing agents because they can displace metals of lower reactivity from their compounds.

A mechanochemical process called Rapid Oxidative Leach® (ROL®) is the gamechanger for miners struggling to extract copper and gold from lowgrade ores. The technology leaches 9799 percent copper directly onsite in six to eight hours, from concentrates as low as 5 percent copper. In gold, ROL has the potential to unlock the value of undeveloped refractory gold deposits with less than 3 g/t ...
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
· The first use of mercury in a large scale mining process was 1828 but evidence suggests that the use of mercury to extract gold from ore may have been first used over a thousand years ago. It is popular among small scale prospectors because it is cheap and simple to use. This was not necessarily the case for larger scale mining operations. Few largescale mining operations use mercury .
