Development South Africa



Electrowinning is an industrial hydrometallurgical technique employed world-wide to produce metals from ionic solutions. The standard technology employed all across the world is based on intellectual property developed more than 100 years ago; working in a semi-batch fashion, requiring manual operation and heavy lifting equipment.

A novel technology was developed at the University of Pretoria that produces various metals, specifically copper on a continuous basis; negating the need for extensive operator interface and heavy lifting equipment. This leads to higher operating efficiencies and most importantly increased worker safety. Other metals include platinum group metals, gold, silver, nickel, zinc, cobalt and many more.

This business plan will outline the projected strategies to introduce this patented technology into the marketplace and operate it as a profitable commercial entity.



Ryno Pretorius – Founder

Ryno Pretorius currently focuses most of his efforts into the bridging of the gap between applied academic research and profitable industrial, application thereof. He is currently pursuing the commercialization of a patent in electrolysis aimed at automation of the electrowinning industry as well as a patent that will produce neodymium trifluoride by means of a waste-less process. He began working as a consulting engineer while completing his Masters in Chemical Engineering. Initially starting out as a computational fluid dynamic simulation contractor, this has branched out into design and development of various processes. He has research and development experience in the mining, nuclear and fluorine chemical industries respectively. He has also provided consulting services to the general process engineering field in terms of process optimization and process design. Ryno is currently completing his Ph.D. in chemical engineering in the field of fluorine chemical process design.

Recently Ryno has been offering his services as a specialist technical consultant to private corporations and public enterprise firms regarding resource planning and value chain development.
