Microwave pretreatment of a low grade copper ore to enhance milling performance and liberation
(Stellenbosch : University of Stellenbosch, 2006-03)
As easy to mine high grade ore bodies are being depleted, many mining industries are experiencing an increasing need to process lower grade ores, and thus the high costs involved in the mineral recovery from these ores ...
Understanding the effects of mineralogy, ore texture and microwave power delivery on microwave treatment of ores.
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: Previous work has shown that microwave heating of mineral ores induces fractures around grain boundaries due to the differences in absorption of microwaves and the resulting differential thermal expansion ...
A modelling framework to determine the value proposition of microwave treatment of mineral ores
ENGLISH ABSTRACT: The extraction of mineral values from ore requires liberation of the minerals followed by separation. Liberation is achieved by size reduction operations which are inefficient processes typically ...
