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
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
Fly ash, is a waste by-product from the coal-fired electricity generating stations. Power stations need to dispose of the fly ash in a safe and environmentally friendly manner, making the need to utilize fly ash important. The production of zeolites is one way to beneficiate the fly ash waste where

Green Coal is environmentally friendly coal briquettes produced from discarded fine coal, bio-char material, and proprietary chemical binders. The briquette reduces sulphur emissions during combustion by approximately 50%, while also increasing the burning effectiveness. The bio-char addition to the

Green Clean Surfaces for Safe Food Preparation Nutridx® is a disinfectant enhanced by the addition of a natural anti-microbial compound. It has been specifically formulated to disinfect and sterilise of food and food processing equipment as well as internal and external hard surfaces. It has been

Sol-gel Long Lasting Power These long-lasting and significantly safer batteries are novel because of their sol-gel base. A uniform carbon coating process produces high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce

Coarse particle transportation is essential for moving slurries, or fluids containing very high concentrations of pulverised solids, for example, hydraulic transport of coal ore or waste materials. Due to a scarcity of water and a high concentration of the solid particles, pipe blockages are common
