The Colorado Fuel and Iron Company (CFI) was a large steel concentration. By 1903, it was mainly owned and controlled by John D. Rockefeller and Jay Gould''s financial heirs. While it came to control many plants throughout the country, its main plant was a steel mill on the south side of Pueblo, Colorado and was the city''s main industry for most of its history.
SRK''s mine ventilation services team specializes in solving ventilation and climatic problems associated with the operation of mines and other subsurface facilities, including those which pose special challenges due to unusual geographic or geologic conditions.
A total mill ventilation system can lower millwide dust concentrations, hence reducing respirable dust exposures of workers in mineral processing operations. The system uses clean air drawn in at the base of the building to dilute and remove dust from contaminated areas within the mill structure.
It is usually said that mining in the area ceased because the mines "played out". What makes that interesting is the fact that lead and zinc were found at least as far south as Spavinaw!
The regulatory document pertains to any ventilation of uranium mines and mills for the purpose of assuring the radiation safety of workers and onsite personnel.

The Macassa Mine, located in the Town of Kirkland Lake, Ontario remains one of the highest gold grade mines in the world. Macassa commenced operations in 2002, and with the discovery of the South Mine Complex (SMC), has been able to increase its level of production significantly over the past five years.
The tunnel would provide water drainage, ventilation and economical transportation of the gold bearing ore from the many mines it would intersect along the way. The Argo Mill was constructed to process the gold bearing ore from these mines. When completed, the Argo would be the largest mill .
