Leaching requires canals and ponds for the conduction and retention of liquid solutions pre and post treatment It also requires lagoons for the final disposal of sludge or primary sedimentation Our custom made environmental pond nets make this process safer by creating a permanent effective barrier between these bodies of liquid and the environmentGold cyanide method is the process of dissolution of gold ore using cyanide chemicals because every atom of gold requires dissolution of the mineral carrier or impurity with the stoichiometry of two cyanide soluble compounds
