摘要：

The milling of refractory gold ore at Giant Yellowknife Mines limited results in several effluent waste streams which are combined and sent to a tailings pond. Prior to being released to the environment, tailings effluent is treated to make the solution environmentally acceptable. This involves removing contaminant such as cyanide, arsenic and heavy metals. In 1976, Giant Yellowknife Mines and Environment Canada entered into a DPAT (Development of Pollution Abatement Technology) program to investigate various treatment processes for the removal of cyanide and arsenic including those stated. In August 1981, the Effluent Treatment Plant became operational, employing an alkaline chlorination-arsenic precipitation-flocculation process. This paper describes the development of the effluent treatment process, process chemistry, plant facilities, plant practice and reviews the Effluent Treatment Plant performance over its six seasons of operation to date.
