An Investigation of Selective Galena Recovery Following Its Depression
It is challenging to obtain a final lead concentrate from copper-lead-zinc ores due to the complex mineralogy of the ore and the similar flotation behaviour of minerals within the ore. This study was carried out to investigate ...
An Economic and Financial Deconstruction of the Commodity Streaming Business Model
The objective of this thesis is to evaluate the viability of the commodity streaming business model, both as a standalone enterprise and as a financing service for exploration and mining companies. A silver streaming ...
Ventilation design strategy to meet future production requriements for a Saskatchewan potash mine
The Potash Corporation of Saskatchewan Inc. has invested 2.8 billion dollars in its Rocanville Division, a potash mine in southeast Saskatchewan. The investment was made to increase site production nameplate capacity ...
ANALYSIS OF SEISMICITY IN MINES AND DEVELOPMENT OF RE-ENTRY PROTOCOLS
Following a large seismic event in hard rock mines, there is a short-term increase in aftershock activity, which over time decays to background levels. During this time of elevated seismic activity the risk of aftershocks ...
Timing Effects on Fragmentation by Blasting
Rock fragmentation has always been an indicator for the efficiency of blasts in mines. Several suggestions have been made by blast operators and specialists to improve the rock fracturing mechanisms in order to obtain ...
Small Scale Study of the Role of The Muckpile in the Blasting Fumes of Commercial Explosives
Blasting fumes are an important safety topic for the mining industry because toxic fumes are generated by the detonation of explosives. Prediction of the amount and concentration of blasting fumes is important for underground ...
Microwave Vacuum Carbothermic Reduction and Sulphidation of a Low Grade Nickeliferous Silicate Laterite Ore
The international resources of nickel sulphides are quickly diminishing. In order to satisfy forthcoming nickel demands, the feasible mining of nickel laterite deposits is imperative. Nickel laterites cannot be easily ...
A Study on the Role of Sulphur in the Thermal Upgrading of Nickeliferous Laterite Ores
As the global demand for nickel continues to increase and the nickel sulphide ore deposits are depleted, there is considerable interest in the exploitation of the nickeliferous laterite ores. However, current processing ...
An Investigation of Diggability and Other Digging Effort Related Metrics for Cable Shovels at Multiple Mines
A performance monitoring study was conducted aboard electric cable shovels at three different open-pit mines for the purposes of quantifying digging effort. A comparative analysis of public domain diggability metrics was ...
