Mineral Asset Valuation Codes: Towards an International Standard
To facilitate an efficient process of asset price determination in minerals industry markets, participants require materially complete, accurate, and timely disclosure of information. The standardization of reporting related ...
INVESTIGATION INTO THE THERMAL UPGRADING OF NICKELIFEROUS LATERITE ORE
Nickeliferous laterite ores are currently processed using complex energy intensive flowsheets. Limited mineral upgrading can be achieved by low-cost mineral processing as the nickel is not found as a separable mineral phase ...
ADSORPTION OF POLYAMINE CHELATED COPPER IONS ONTO GANGUE MINERALS AND HIGH CAPACITY ADSORBENTS
The effluent quality from mining & processing operations is monitored to ensure that maximum allowable limits are not exceeded. Recently, copper concentration levels in the effluent discharge flows of a copper and nickel ...
A Study of Flotation and Leaching Behaviour of Bornite and Chalocpyrite
This study was carried out to investigate the flotation and leaching behaviour of bornite and chalcopyrite when they are together as principal sulphide minerals. Bench scale flotation performance was examined both in the ...
Remote Surveying of Underground Cavities Excavated by Jet Boring
Cigar Lake is a high-grade uranium deposit, located in northern Saskatchewan, Canada. In order to extract the uranium ore remotely, thus ensuring minimal radiation dose to workers and also to access the ore from stable ...
Automatic P-wave Picking of Microseismic Events in Underground Mines
This thesis investigates microseismic P-wave arrival time detection performance of automatic picking algorithms, as well as the handpicking performance of human experts. The data set used in this project was collected from ...
