Projects

Mogalakwena is the largest platinum concentrator in the world – a 600 kilo ton per month giant, was undertaken by a joint venture between DRA and TWP.

The scope of work included the engineering design, procurement, construction, management and commissioning of everything from the run of mine primary crusher to the wet process plant.

The system built and installed included:

• A 60’ x 113’ primary crusher with a 1 MW drive, capable of crushing material from 1200mm to 475mm
• A 600kW secondary crushing system for reducing material to -65mm
• A high-pressure grinding roll (HPGR_ with two 2800kW motors enabling it to produce a product size of -8mm ate a feed rate of 1270 dmtph
• A primary mill fitted with a 17.5 MW gearless drive
• A rougher flotation system featuring two parallel banks with a feed rate of 450 dmtph
• A single 7.9m dia x 11.7m long 17.5 MW gearless drive secondary mill with a capacity of 900tph, producing a final grind of 80% -75µm
• Four 35m dia thickeners for intermediate float, two 35m diameter units for concentrates and four 12 diameter units for ultra-high rate final tails
• The concentrate handling facility itself features 144m2 filters

Mogalakwena has a mine life of more than 30 years with potential to extend further. DRA is currently engaged in the feasibility study for the expansion of the mine, which includes possible underground mining options.
