Manipulating aqueous chemistry environments in extractive metallurgy
… Anglo Research Nickel (ArNi) process is a novel extractive metallurgical process that arose out of the need to develop a processing route for the recovery of nickel from lateritic ore deposits that is both economical and environmentally acceptable.

A study investigating copper smelting remains from San Bartolo, Chile
Introduction: Research on the metallurgy of archaeological artifacts has focused primarily on the examination of objects to reveal their design, their composition, the properties of the material people selected to achieve the design, and the fabrication processes used in managing the metal to …

Corrosion in the Mining Industry: A Case Study of the Britannia Mine
The mining, mineral processing, and extractive metallurgy sectors operate in highly corrosive environments. Equipment, infrastructure, and processing systems are particularly vulnerable to accelerated corrosion under these harsh conditions. The resulting material degradation can lead to structural …

The measurement of liquid height in flotation cells using microwave techniques
The flotation process is used in extractive metallurgy to concentrate the mineral contents of ores by 'floating' the mineral particles out of an ore pulp with air bubbles. The pulp consists of finely ground ore, water and reagents, whose purpose is to make the mineral particles attach themselves to …

Arsenic Oxidation Assisted by Carbon-based Catalysts in Dynamic and Continuous Conditions
… soluble arsenic species released by mining and extractive metallurgy activities were not responsibly and appropriately managed. Most arsenic immobilization techniques are not efficient for treating trivalent arsenic in solutions. In the cases where soluble trivalent arsenic is predominant in the …

Environmental Considerations of Space Resource Extraction
As humanity's desire to travel deeper into space and create settlements on other celestial bodies grows, so too does the need for extracting resources from space. The Moon, Mars and asteroids all contain important resources that could assist in these activities, as well as resources that are …

On the reduction of metal oxides in non-equilibrium hydrogen plasmas
Metal oxides are some of the most widely-used source materials for the primary production of metals. However, the technologies currently used for the reduction of metal oxides can produce deleterious byproducts. Hence, there exists a need to develop improved processes for reducing metal oxides. …

Chlorination of Titanium Oxycarbide and Oxycarbonitride
The project undertook a systematic study of chlorination of titanium oxycarbide and oxycarbonitride with the aim to develop further understanding of kinetics and mechanisms of the chlorination reactions. The project studied titania, ilmenite ores, and synthetic rutile reduced by carbon in argon and …
