Podolsky Mine’s Environmental Challenge

CIM Toronto 2009
Ian Horne, Harry Marshall,
Abstract Striving for zero environmental impact, both short and long term should be every mines aim. FNX Mining believes it is an attainable goal which just requires some hard work and creative thinking.

Ammonia in mine effluent is potentially toxic to fish. The ammonia concentration in mine water is affected by two key factors, the effective use of explosives and dilution of the effluent by ground water.

During the advanced exploration and early operations stages ammonia was removed in a natural bog located to the west of Podolsky mine. As underground activity escalated, the volume of water requiring treatment increased dramatically and ammonia concentrations increased.

There came a point in time when the choice came to shut down the source or run the risk of polluting the receiving environment. A decision was made to stop all blasting activity and all water discharge. The race was on to find a solution to this problem.

This is the environmental story of a small mine’s journey from exploration through to production and how the issue of ammonia in the mine’s effluent was brought under control by engaging the work force, using temporary pretreatment on surface and finally the introduction of a state of the art treatment facility.

Summary: Cobalt is not generally found alone in commercial deposits but mostly occurs as a small but valuable constituent in most nickel and a few copper ores . Its concentration and extraction are therefore intimately linked to the recovery of the primary metals and the major task for the metallurgist is to extract cobalt of commercial grade from a much larger mass of either nickel or copper and sometimes both. This paper provides an overview of the mineralogy of the main deposits being currently...

Summary: The management and leadership of a mining operation is a challenge at all times. The pressure to make production, safety, and environmental goals is intense. At some point mining cycles will put every operator into periods of time where economic issues seem to over-ride all other concerns. This is when leadership is most needed. People are looking for leadership at these times, and if we lose focus on getting the job done safely, it can be disastrous. From catastrophic incidents due to...

Summary: Predictive estimation of aqueous ammonia concentrations for open pit, mine project environmental feasibility studies is inadequately documented. A universal ammonia range has been proposed, but does not take into account temporal variability, which can be substantial in northern latitudes. A predictive model suitable for open pit mine environmental studies, drawing on agricultural industry research, is described. The quarterly model incorporates ambient temperature, wind speed, rainfall,...
