This applies to the production of copper (Cu). nickel (Ni), zinc (Zn), cobalt (Co) and other non-ferrous metals.The basic chemicals used in this process are:Hydrochloric acid (HCl), Sulphuric acid (H2SO4). nitric acid (HNO3). various salts, special chemicals.The resulting waste must be processed- mainly waste acids and sulphur dioxide (SO2)Storage tanks, process vessels and pipelines are used here.
