    This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries. First, concentration

  • An environmentally friendly way to process gold |

    28.05.2013· A team of scientists there have discovered an inexpensive and environmentally safe way to isolate gold from raw materials. Basically, the scientists have found that they can use simple cornstarch, instead of cyanide, to do so. It extracts the gold and leaves behind other metals that are often found in crude gold.

  • Responsible Mining and Energy - Conservation

    Toxic levels of mercury are released from coal-burning power plants and from mercury amalgamation, a practice used in illegal and small-scale gold mining that results in about one unit of mercury emitted into the environment for every unit of gold produced. This practice leads to almost 1,000 tons of mercury released into the environment each year.
