ERG Tailings Retreatment Project

"INTRODUCTIONGold tailings retreatment plants have been operated for many years throughout the world. Several large tailings retreatment facilities have been operated profitably in South Africa since 1976 and there are tailings retreatment operations in Canada currently in production with more in the feasibility stages.The Timmins Gold Tailings Project of ERG Resources Inc. was designed to treat 8,000,000 tonnes per annum of gold tailings for an eight month operating season, and commissioning of the operation began in July 1988. The payback period for this project is about 3 years which corresponds to an IRR of 30%.This report summarizes the metallurgical characteristics of the reclaim tailings, describes the process flowsheet which was developed to enable ERG to economically recover gold from the Timmins area tailings, and reviews commissioning activities."
