The preparation of activated carbon from South African coal for use in PGM extraction
(North-West University, 2007)
Activated carbons used in the Platinum Group Metals extraction industry are characterised by large internal surface areas and a great affinity for platinum, palladium and ruthenium. It is therefore necessary in this study ...
The characterisation of the corrosion and degradation of atomised ferrosilicon in a dense medium circuit
(North-West University, 2003)
The Kumba Resources Sishen Iron Ore Mine is one of the biggest iron ore producers in South Afica, where beneficiation of the iron ore is done using a dense medium separation process. Ferrosilicon is used as the dense medium ...
An investigation into an improved method of dewatering fine coal
(Potchefstroom University for Christian Higher Education, 2003)
Dewatering coal, and especially fine coal (-600μm), is a significant problem in the preparation of coal. The final moisture level of fine coal can be anything up to 30% by weight, depending on the type of dewatering equipment ...
Experimental investigation into the application of a magnetic dense medium cyclone in a production environment
(Potchefstroom University for Christian Higher Education, 2001)
The magnetic dense medium cyclone project was undertaken at Koingnaas Mine on a 250 mm diameter cyclone during 1998 and a 510 mm cyclone during 2000. The aim of the project was to evaluate the performance of a magnetic ...
A study of the influence of thermal drying on physical coal properties
(North-West University, 2009)
One of the major issues facing the coal industry today is the decline in economically recoverable reserves, especially in the Witbank 1 Mpumalanga region of South Africa. This necessitates a critical review of alternate ...
Investigation of coal agglomeration in a non-pressurized gasifier
(North-West University, 2008)
The gasification process is vital to various applications, such as the manufacture of products in the petrochemical industry, for example chemicals, diesel and petrol. The importance of gasification to the coal industry ...
