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

The invention relates to the use of maghemite nanoparticles at pH less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline

Air quality is a concern worldwide. Consequently, efficient means to monitor air pollutants are critical. Current commercially available carbon-based sorbents used for sampling volatile organic compounds (VOCs) in air typically require solvent extraction prior to analysis, and they cannot be reused

A new technology that provides the first ever high-throughput 3D imaging of locked diamonds within kimberlite rocks. Locked diamonds of up to 10cm in diameter can now be located within rocks before the crushing process begins. Conventional sorting as well as other more recent sorting technologies

The Sprinkler Guard is an innovative irrigation sprinkler riser technology designed to overcome the limitations of conventional above-ground sprinklers, which are often prone to mechanical damage, disorientation, and poor aesthetics. Traditional rigid riser pipes not only shorten the lifespan of

MagNanoClean™ is an innovative method and apparatus for fluid treatment that leverages charged nanoparticles and a moving magnetic system to remove impurities efficiently and sustainably. In this process, contaminants are trapped by the charged nanoparticles suspended in a reactor. When activated
