Alternative uses of coal in the production of advanced materials and lightweight products for the sustainability of the South African coal industry
Desktop review commissioned to shape a five year coal processing research roadmap, covering rare earth recovery, carbon fibre, graphene, activated carbon and building products. For research planners.
Coaltech | October 2023
Coal can feed products well beyond combustion. The study sets out routes to rare earth elements held in particular seams, building materials made with carbon fibre and carbon char, coal foam and graphene composites, carbon black and activated carbon, including a coal derived activated carbon reported to hold four times the gas of compressed natural gas at lower pressure.

Description
This report seeks to present a new approach to the evaluation of coal and its alternative applications as a resource for a wide array of high-tech and high-value products made using innovative, economic and responsible technologies. The objective is to present examples of new developments and currently operating ones drawn from international sources that could serve as examples for the South African coal community to aspire to. From this base, South African corporate entities can assess the opportunities to use South African coal in this new manner and expand into these areas of applications. By doing so, demonstrate a wide range of advanced manufacturing opportunities for development in South Africa.

2008
Structural study of dolerite dykes and sills at four collieries south of the Ogies Dyke, linking intrusion geometry to mining conditions and coal quality. For mine geologists.
What this report foundDolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield.

Dolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield. In decreasing order of importance, intrusions cut safety by raising the risk of roof, pillar and floor failure, raise mining costs, reduce saleable tonnage, and increase waste generation and environmental risk.
The impact of cattle grazing on rehabilitated land
Two annual surveys of species composition, biomass and soil sampling inside and outside fenced plots on rehabilitated pasture at an opencast colliery near Ogies, with benchmark sites for comparison.
What this report foundGrazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity.
R1500,00
Grazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity. The sward was dominated by low quality grasses with a high proportion of bare ground and a raised erosion risk. Fenced exclosures over one year changed the abundance of a few species, but the vegetation showed no clear direction of recovery.
