A Field Study on Haul Time Variability in Open Pit Mines
As open pit mines get larger and their road networks more complex, haul road traffic is an area of increasing concern for mine operators. In particular, engineers from Barrick Gold Inc. have observed haul truck interactions ...
Architecture of a Classification System to Evaluate Fault Slip Risk in a Mining Environment
As the depth of mining increases, so does the risk of fault slip related rockbursts. Currently, there is no way to evaluate this risk, however the need for such a system is clear. Fault behaviour in mining environments ...
Stochastic Dynamic Optimization of Cut-off Grade in Open Pit Mines
Mining operations exploit mineral deposits, processing a portion of the extracted material to produce salable products. The concentration of valuable commodities within these deposits, or the grade, is heterogeneous. Not ...
Open Pit Mine Planning: Analysis and system modeling of conventional and oil sands applications
In the last decade mineable oil sands production in Canada has grown rapidly. Constraints on the planning and design processes employed by surface mining oil sands operations vary in distinct ways from other commodities ...
An Investigation into the Sulphation Roasting of Enargite Concentrates
Potential new ore deposits containing significant levels of enargite, a copper arsenic sulphide mineral, are being considered for development. The processing of high arsenic copper concentrates directly in copper smelters ...
THE SELECTIVE SULPHIDATION AND PHYSICAL UPGRADING OF NICKEL FROM A NICKELIFEROUS LATERITIC ORE
The processing of nickeliferous laterites to produce nickel metal is both complex and energy intensive. Since most laterites are found in remote regions, the capital costs for the infrastructure can exceed those for the ...
