What is biomining? American Geosciences Institute

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

Biomining Wikipedia

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.

Gold Geoscience Australia

Most gold mined in Australia today cannot be seen in the rock, it is very fine grained and mostly has a concentration of less than 5 grams in every tonne of rock mined. The feasibility of mining low concentrations of gold largely depends on the price of gold. Gold is bought and sold every day on international gold markets.

Gold Properties, occurrences, and uses Britannica

Gold Gold Properties, occurrences, and uses: Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf. Because gold is visually pleasing and workable and does not

Pollution. Mercury is one of the most harmful pollutants to both people and wildlife. Toxic levels of mercury are released from coal-burning power plants and from mercury amalgamation, a practice used in illegal and small-scale gold mining that results in about one unit of mercury emitted into the environment for every unit of gold produced.
