CRB - About Us
Welcome to the Focus Area for Chemical Resource Beneficiation Located in a mineral-rich province, the CRB aims to enhance the sustainable value of South Africa's mineral and chemical resources, which includes both metal-based resources such as platinum group metals, and carbon-based resources such as petrochemicals. In alignment with the NWU…http://natural-sciences.nwu.ac.za/crb/director%2527s-message
Director's Message
The research focus area for Chemical Resource Beneficiation (CRB) in the Faculty of Natural Sciences comprises participants of the School of Physical and Chemical Sciences, the School of Chemical and Mineral Engineering and the School of Pharmacy. The combination of these related disciplines ensures a competitive advantage to offer the…http://natural-sciences.nwu.ac.za/crb/conferences

The CRB focuses on adding value to the SA national mineral and chemical resource base found in the North-West and Southern Gauteng provinces. This can be divided into two key knowledge areas, i.e. metal-based resources (such as the platinum group metals and chromium) and carbon-based resources (such as petrochemicals, plant oils and…http://natural-sciences.nwu.ac.za/crb/conferences/catsa2011

Process Intensification
Based on past experience on in-house manufactured zeolite coated ceramic membranes, current research is continuing on the use of zeolites and zeolitic membranes combining their catalytic properties as well as their ability to act as molecular sieves. /sites/natural-sciences.nwu.ac.za/files/files/CRB/imagesSintering…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/gas-separation
Gas Separation
While gas permeation studies form an intrinsic characterisation tool both for the inorganic as well as organic membranes for various applications, there are ongoing projects focussing specifically on the resolution of various perfluorinated compounds. These projects focus mainly on finding membrane based separation processes to replace…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background
