What is Heap Leaching with picture Learn About the Heap Leaching Process Mining

22/10/ 32 Heap leaching is an industrial process for extracting precious metals and minerals by dissolving them from ore with liquids known as leaching solutions Unlike conventional ore refinement processes which utilize extremely high temperatures and highly toxic chemicals heap leaching offers operators an effective low cost solution with little if any negative environmental impactLeaching solutions or lixiviants used in heap leach mining are either highly alkaline such as sodium cyanide or highly acidic such as sulphuric ac To ensure uniform distribution of the lixiviant to the ore heap and to minimize evaporation drip irrigation systems are the preferred distribution method
