The recovery of magnesium oxide and hydrogen chloride from magnesium chloride brines and molten salt hydrates
Hydrochloric acid leaching of saprolite nickel ores has been proposed as an effective means of recovering nickel and cobalt. However, the leach produces a concentrated brine of magnesium chloride which must be hydrolyzed ...
The Contribution of Geomechanics and Engineering Geology to Mine Enterprise Value
The objective of this thesis is to identify the value of geomechanics and engineering geology to mine enterprise value for hardrock underground mines. It was decided that the most effective way to highlight the value of ...
Seafloor Massive Sulphides: Assessment of Sustainable Mining Potential through an Iterative Decision-making Framework
Extraction of metals from the seafloor has been considered for decades, beginning with manganese nodules in the 1970s. Today, the targets are massive sulphide deposits rich in copper, zinc, gold, and silver that are ...
An Investigation of Leaching Chalcopyrite Ore
The abiotic leaching behavior of a chalcopyrite ore, from Asarco’s Ray-Mine, was conducted in shake flasks and miniature columns at elevated temperatures. The shake flask tests, with an ore particle size of 1.18mm-2.38mm, ...
Remediation of Mine Tailings by Nano-Scale Zero-Valent Iron
The purpose of this thesis was to investigate the potential ability of nano-scale zerovalent iron (nZVI) to remediate multiple metal contaminants, specifically in the context of mine tailings. The project began by adopting ...
Production and Application of AlCl as a Reductant for Solar Grade Silicon Manufacture
Solar grade silicon is currently produced mainly through blending semiconductor grade silicon waste with metallurgical grade silicon. As the demand for solar cells continues to increase rapidly, soon demand will outstrip ...
