Environmental Considerations And The Modern Electrolytic Zinc Refinery - Chapter 14

Recent legislation and the heightened environmental awareness of the public have brought about constraints in the location, process selection and operation of the modern electrolytic refinery. The modern electrolytic zinc process incorporating pyro, hydro, and electrometallurgy has emissions, effluents and residues which are acceptable only under severely restricted discharge conditions. Due to the necessity of maximizing zinc recovery, the additional cost of the environmental equipment has to be minimized, which may be achieved by intelligent process and location selection as well as by proper operation of the plant for maximum return to the Owner and minimum damage to the environment.
