Bioleaching 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

Westwood is currently IAMGOLD's only underground mine, and has an average resource grade of 10 grams of gold per tonne. With our ongoing focus on production efficiency and cost reduction, we are reviewing life-of-mine profiles with production ranging from 165,000 to 180,000 ounces at average cash costs between $630 and $690 per ounce.
The Kibali mine has been developed in two phases. Phase 1, which encompassed the KCD open pit operation and processing plant, the mine infrastructure (including a 36-unit high speed thermal power station) and the first of three hydropower stations, was completed in December 2014.
Full capabilities for gold and precious metals analyses are available in many of Bureau Veritas' locations around the globe. Fire assay is unrivalled as the preferred method for economical determination of total gold concentration exploration, mine production and mineral processing samples.
Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
