Pollution Control Problems In The Canadian Mining Industry

CIM Bulletin, 1973

W. R. HORN, Research Co-ordinator, The Mining Association of Canada

I tried to convey: that the awareness and alertness of this far-flung and diversified industry was sharply on the up-swing; that the knowledge of helpful technology for the abatement of pollution by water and solids was significantly increasing; that most mines were doing something about it; that many had already achieved a recycling of process water to a really significant extent; that progress was being made - though not without considerable difficulty - on the large-scale neutralization and subsequent chemical treatment of acid- and metals-bearing waters; that increasing work was being done by individual mining companies on methods for the vegetation of completed tailings impoundments; and that it had been possible to develop a meaningful estimate of the amount of money to be spent by the industry on environmental control measures during the period 1971-75 (as much as $500,- 000,000 ) . Reference was also made at that time to the constructive work in hand toward the fixation, elimination or dispersion of sulphur from smelters and to the considerable attention which was being given by the industry itself toward in-plant problems, e.g., dust and noise. Finally, note was taken of the fact that the inclusion of environmental control costs in the pre-operational financial provisions of new mining operations is now established practice.
