    Process DevelopmentSelecting A ProcessGold RecoveryAmalgamationFlotationLeachingGold recovery comprises similar stages to the processing of most ores. First, the valuable minerals are separated from the gangue through concentration. The final concentrate is obtained by repeated processing and is smelted or leached in order to get a Dore bar. In generals, the concentration of gold includes three stages roughing, cleaning and scavenging. The reason of concentration is to separate the raw material into two products, concentrate and tails. Ideally, in free gold recovery, all the gold will be iQuoted Price
  • Mining amp; Extraction Global Forest Atlas

    Mining has always been an environmentally disruptive activity, but contemporary extractive industries are located in some of the most ecologically sensitive forests in the boreal and the tropics. Oil, gas, and mineral extraction account for an estimated 7% of global deforestation in the subtropics, with increasing exploration and development taking place in the Amazon and Congo basins.
