Book Description
Mining of placer gold generates wastewaters containing high concentrations of fine sediment. Previous studies have concluded that the most practicable method of placer mine wastewater treatment is some form of settling pond system. This report first reviews the major factors that influence placer mining effluent quality and describes mine site constraints for different types of operations. It then reviews the applications and limitations of sedimentation theory and alternative pond design methods as shown in previous studies. A recommended design approach is presented. The next section describes detailed design criteria for settling pond systems, including those relating to data determination, pond size, and pond layout. The final sections review applications and limitations of alternative wastewater treatment methods, and outlines requirements for further research on settling pond systems.
