The North-West University has developed a method in which municipal wastewater is treated to remove ammonia and phosphate while simultaneously recovering struvite as a byproduct. Struvite is used to reduce the acidity of acidity of the acid mine drainage water which leads to precipitate metal
Chalcopyrite is a common but low-grade copper ore, and NWU researchers have developed an innovative method to improve copper dissolution and extraction from this mineral. This is achieved by harnessing galvanic interactions between chalcopyrite and magnetite, they achieved more efficient copper
The Rotatable Fish Drying Frame is aimed at formalising a specific fish-drying process already used by different communities in Africa. The frame allows for the drying of up to 100 kg of fresh fish at a time using the existing iteration. The key principle is that after one week of drying the drum
Background The nucleus of a cell is central to the well-being of any living organism. It stores and organises information from other cellular components and protects this information. It communicates with the rest of the cell, exchanges RNA and facilitates several important processes. The nuclear
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
Background A Magnetic Resonance Imaging (MRI) scanner applies magnetic fields to a human or animal in order to generate an image of a specific region of the body. Due to a number of internal and external effects, these fields are never completely homogeneous. Distortion of the magnetic fields may
Background: Biomedical studies (e.g., prosthetic development and injury rehabilitation), sports science research, high-performance optimization research and assessments, and bipedal or quadraped movement measurement often require accurate measurement of the forces exerted by the subject being
Postharvest table grapes are susceptible to fungal infection even when stored at the optimal temperature of −0.5°C. The most important pathogen of stored Table Grapes is grey mould, which is caused by Botrytis cinerea. Some countries fumigate their grapes with sulphur dioxide gas. However, if the
The Bambara Groundnut, or round bean, is widespread in Africa where it is known by various names. It has potential as a cash crop, owing to its nutritional composition, functional properties and antioxidant potential. Consequently, we at CPUT have used the Bambara Groundnut as a raw material to

LeguPro is a protein-rich pasta, which is produced from non-traditional pasta ingredients such as peanuts, soybeans, and chickpeas. It is a cost-effective nutrient-dense high protein, healthy instant noodle product and aims to give consumers an alternative staple food product to be consumed as is or

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
