Glencore’s Tweefontein coal processing plant in Mpumalanga South Africa, is one of DRA Global’s largest EPC projects to date. It involved the replacement of three existing 9 Million tonne per annum Coal Preparation plants (CPP) into a single plant. The CPP was designed for a raw coal feed capacity of 12.5 Mtpa and featured two 1 000 tph modules, a two stage, primary and secondary dense medium cyclone facility for coarse coal and a spiral-based unit for fines coal processing.
DRA Global’s scope further extended to include all infrastructure associated with the 18 MVA power-consuming CPP, starting from the ROM tip all the way through to the rail load-out facility. During this project DRA Global made use of virtual construction simulation software, this integrated software allowed DRA Global to greatly mitigate risks, improve safety and optimise constructability, enabling project delivery 6 months ahead of schedule. As a result, the Tweefontein Coal project won the award for “Best Civil Engineering Project of the Year”.
