phytomining and bioleaching

Bioleaching | Detailed Pedia

Method of metal extractionBioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.Contents1 ...

Bioleaching - SlideShare

Bioleaching • "Bioleaching" or "bio-oxidation" employs the use of naturally occurring bacteria, harmless to both humans and the environment, to extract of metals from their ores. • Conversion of insoluble metal sulfides into water-soluble metal sulfates. • It is mainly used to recover certain metals from sulfide ores.

Bioleaching (Biomining) Advantages, Process & More | Anglo American

The 3 most common commercial biomining processes are: 1. Slope Leaching Fine ore is kept in a large, slope-shaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2.
