WebBiohydrometallurgy Biohydrometallurgy is a technique by which microorganisms are used to recover certain metals from ores. The technique was first used over 300 years ago to extract copper from low-grade ores. In recent years, its use has been extended to the recovery of uranium and gold, and scientist believe that it will eventually be applied to the … Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas:
