A prominent open pit mining company in McLeese Lake, British Colombia developed an efficient copper leaching process. A mild sulphuric acid is sprayed over low-grade copper ore and the resulting leachate is collected in a series of dykes and draining ditches, then into holding ponds before processing. Pultex FRP structural components are ideal for this application due to the corrosive environment. They are also lightweight for easy installation and optimal design.
