An economic impact analysis of mineral beneficiation in Kwazulu-Natal's iron and steel and aluminium value chain
This paper examines mineral beneficiation within the aluminium and iron & steel industries in Kwazulu-Natal and the associated value chains. Multiplier analysis is used in conjunction with the provincial social accounting matrix to determine the knock on effects of increased beneficiation, …

Sustainability performance analysis and decision-making for minerals beneficiation : a South African iron and steel scrap case study
It is widely accepted that downstream mineral resource beneficiation has the potential to promote socio-economic growth in resource-rich nations. Many African countries, including South Africa, are thus prioritizing mineral beneficiation in their national policies and development strategies. …

Investigating strategies to improve superior sustainable performance in the Namibian mining industry
… to its products via the implementation of the Mineral Beneficiation Strategy (MBS). Unfortunately, the mining industry is currently unsustainable because 52% of the operations have stopped production. This research is aimed at investigating strategies that may potentially improve superior …

Development of a heuristic methodology for designing measurement networks for precise metal accounting
… to the precise accounting of metal flows in mineral beneficiation operations. The term 'measurement network' is used to refer to the 'system of sampling and weight measurement equipment' from which process measurements are routinely collected. Metal accounting is defined as the estimation of …

Strategies for the regional planning of the minerals industry in Southern Africa : the case of the SADCC
… The region is exceptionally rich in mineral resources and, as a whole, the SADCC falls within the classification of a "minerals economy'. The minerals sector currently has the role of providing the state with foreign exchange and revenues as almost all minerals are exported. Due to …

The effect of copper sulphate on froth stability
Froth flotation is a mineral beneficiation process implemented in the recovery of valuable minerals from unwanted gangue material. Copper sulphate is used as an activator in the flotation of base metal sulphides (BMS) as it promotes interaction of collector molecules with the mineral surfaces. It …

The effect of microbial load and water recycling on the flotation performance of a PGM bearing ore
Mineral processing requires large quantities of water for its operations. With the continuing move to reduce freshwater withdrawal and mine water discharge, the mineral industry has been applying water recycling and reuse to improve water use efficiency. Previous studies on the use of remediated …

Early-stage design and development of mine waste valorisation technologies with expert input: a case study of South African sulfide-enriched coal waste
Mining and minerals beneficiation typically result in the production of both valuable products and large bodies of waste, which are traditionally disposed of on land and carry environmental and social risks. Circular economy and resource efficiency trends have shifted the focus from disposal to …

Desulphurisation flotation for the selective removal of pyrite from coal discards using microorganisms
Mineral beneficiation processes such as base metal and coal mining produce large amounts of waste rock and coal discards that contain significant quantities of sulphide minerals with Acid Rock Drainage (ARD) generating potential. ARD is caused by the exposure of sulphide minerals, primarily pyrite …

The effect of ion accumulation owing to water recycling on flotation performance
… and process water seepage into the water-table. Mineral beneficiation entails different unit operations; amongst them is froth flotation. Froth flotation is a multifaceted complex process which is water intensive and to manage water usage, the global mining industries are now recycling water. The …

Resource intensity trends of ferrochrome production in South Africa
… and infrastructure. The industry, like other mineral industries, has made a significant contribution to the socio-economic development of South Africa. The South African government, through the Department of Mineral Resources, has drafted a mineral beneficiation strategy that is focused on …
