Mining is the process of mineral extraction from an ore or rock seam The minerals can range from precious metals and iron to gemstones and quartz In ancient times miners recognized a mineral rock formation from its outcrop at the surface Modern mining technology uses geophysical techniques that involve measuring

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi 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 It was discovered in the mid 1900s that microorganisms use metals in the cell
