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

This system involves the process of taking soil samples from a potential building site, mixes it with water and then the sedimentation process is evaluated by a camera and analysed to determine how much clay is in the soil sample. This in turn will then provide the engineers with information on what

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

The cost of building materials contributes significantly to overall construction costs, with ordinary Portland cement (OPC) being one of the main components. The production of OPC is not environmentally friendly. It is energy-intensive, uses natural resources such as limestone, and produces high

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

Floatation Device is a system that acts as an anchor and elevator for equipment, shacks and mobile houses that would otherwise be affected by flooding. During the rainy season, the Floatation Device elevates the items away above the stormwater and provides stability to secure items from damage or

The product is a locally produced, cost-effective plant health diagnostic tool. A collection of plant virus antisera is maintained at the Virology unit of ARC-Plant Health and Protection (ARC-PHP). The antisera were manufactured from plant viruses obtained from various crops in South Africa, thus

Stumpout®: Protecting Indigenous Fauna with a Fungus Black and golden wattle trees (Acacia mearnsii and Acacia pycnatha) are considered an invasive alien species in South Africa, they out-compete and replace local fauna and consume more water than many of their indigenous counterparts

Lachenalia: Not A Flower By Any Other Name South African floral diversity is well known worldwide. Gerbera, Gladiolus, Freesia, Ornithogalum, and Protea representing some of the most important floral crops and all of them originated here in South Africa. The world export market for floriculture
