Sommaire: At Teck-Corona Operating Corporation's David Bell Mine, a successful -water quality management strategy has been established. This resulted from the development and application of process technology, allowing year round discharge of an effluent exceeding the chemical and biological standards set by the Ministry of Environment. This strategy aims at minimizing contaminant levels of effluents through optimization of reagent selection and reduction of effluent volumes through maximizing reclaim...

Sommaire: This paper is a brief overview of the role of oxygen in cyanide leaching of gold feeds (e.g. ore, concentrate). As the majority of gold occurs in the elemental state (Au°), its oxidation is of vital importance for dissolution in the cyanide lixiviant. The cyanida-tion at high pH is favourable for the oxidation of Au° with a mild oxidant such as air or oxygen. Beside oxidation of gold, deleterious effects of soluble sulphides, arsenates, antimonates on cyanidation of gold can be...

Sommaire: A scientific testing program, sponsored by the Mining Industry Research Organization of Canada (MIROC), was undertaken on the surface and underground facilities of Inco's Crean Hill Mine to investigate the effectiveness of using dry drilling with a dust control system.
The surface test work consisted of the monitoring of advance rates and bit life while a series of 165 mm holes, wet and dry, were drilled at both mine air (0.69 MPa) and high pressure air (1.72 MPa). The results, based on...
