Description
Coal – Related Regenerative Innovation for Concrete and Segmental Block Pavements
This research project investigated the technical feasibility of incorporating coal waste fines and bottom ash into concrete and segmental paving blocks as partial replacements for conventional fine aggregates. Laboratory results showed that optimised replacement levels can maintain or improve strength and durability while supporting circular-economy objectives through reduced aggregate consumption, waste disposal and production costs.

Practical guidance for opencast operations covers early detection with low cost thermal cameras, prevention, and the treatment methods in current use: water sprays and cannons, sand cladding of highwalls and stockpiles, removal of burning coal by dragline, tipping into water ponds and the treatment of sinkhole areas. A three month full scale trial of sprayed fly ash as an antioxidant is reported.
BCI Chemical Research & Analysis – ion Exchange
2012
Global, regional and South African market analysis of ion exchange resins as applied to mine waste brine, including a United States pilot plant, for technology and investment decisions.
What this report foundIon exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint.
R1500,00
Ion exchange was assessed as a treatment route for brine arising from mine water cleaning, from a market rather than a plant performance standpoint. World demand for ion exchange resins was expected to pass 535 million dollars by 2015, driven by urbanisation, pollution and shortages of clean water in developing regions.
