Fly ash is a waste by-product generated by coal-fired electricity power stations. Due to its environmental impact, there is a growing need for safe and sustainable methods of fly ash disposal. One effective approach is the beneficiation of fly ash through the production of zeolites—a class of
The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

The invention relates to a novel process of partial oxidation of un-agglomerated chromite ore in ferrochrome production processes. The process includes the steps: Providing a source of un-agglomerated chromite ore; subjecting the source of un-agglomerated chromite ore to pre-oxidation at a

Industrial electrowinning is one such example where archaic technology has become the norm, with innovation being limited simply because the process is “good enough”. After doing a fundamental analysis on the electrowinning process, the design team has invented a dynamic solution which improves on

The process consists of two continuous stages carried out under inert, vacuum conditions. In the first stage, cold feedstock is fed into a preheating vacuum oven for ex-situ desulphurization. It is heated to a controlled temperature for a set time to break sulphur–sulphur and sulphur–carbon bonds
The flotation device is an engineered support system designed to protect mobile structures from flood-related damage. Mobile structures such as temporary housing units, construction site offices, or warehouse equipment are highly vulnerable in flood-prone areas. This technology addresses that
Current Proton Exchange Membranes (PEMs), especially Nafion, are costly and produced mainly by a single international supplier (DuPont/Chemours). This monopoly escalates the cost of fuel cells and electrolyzers and limits local manufacturing capacity in South Africa. Because PEMs are the major
