The invention relates to a novel process of partial oxidation of un-agglomerated chromite ore in ferrochrome production processes.

The process includes the steps:

  1. Providing a source of un-agglomerated chromite ore;
  2. subjecting the source of un-agglomerated chromite ore to pre-oxidation at a...

The skin represents the first physical barrier to protect our bodies from harmful toxins, pathogens and dangerous environmental factors and plays an important role in social and visual experiences. South Africans have used traditional herbal medicinal products to increase immunity in...

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...

The technology relates to an upright tubular fixed-bed reactor body comprising of a heat-dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Fischer-Tropsch, which are prone to heat build-up. The heat pipe...

Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies.  These problems are related to navigation, recreation, irrigation and hydropower generation. The complete...

The invention entails an energy-generating system that makes use of polyethylene plastics that would otherwise result in environmental pollution to produce synthesis gas (syngas). Unlike conventional gasification systems that rely on oxygen, this system ensures that the gasification of polyethylene...

A low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate velocity wind and generate electricity efficiently for household use. Large-scale wind turbines in South Africa are located far afield, and the energy generated must be transported back to communities via huge...

South Africa harbours the highest number of rape incidents in the world, and sexual assault and rape cases in the entire SADC region are estimated at a minimum of 55 000 cases per year. Crime scene investigations utilise DNA technology on a regular basis. In cases of rape or sexual abuse, male...

The technology is capable of treating high-temperature wastewater as a membrane for removing oil from wastewater

One of the key challenges with membrane filtration devices is the issue of fouling and concentration gradient build-up on the surface of the membrane, which subsequently decreases its...

In the manufacture of textiles, clothing and leather goods, using a nanoparticle catalyst, this one-step wastewater treatment system activates a powerful oxidiser. This produces sulfate radicals in the wastewater which will degrade the inorganic pollutants. These highly reactive nanoparticles are...
