  • ECO-FRIENDLY Recovery of GOLD and COPPER for the Small

    Small Scale Mining operations recover gold by either Cyanidation and/or Amalgamation because it is simple; Cyanidation and Amalgamation are both hazardous processes because chemicals are used for recovery gold that have been long proven to cause adverse effects to health and the environment; Background The use of low-end technologies in crushing and grinding of ores leads to lack of
