Kumba’s Kolomela mine
Leading dust control and gas-cleaning specialists ACTOM Air Pollution Control of Johannesburg recently completed a R16-million contract to improve dust extraction efficiencies on the secondary and tertiary crushers in the mineral processing plant at Kolomela iron ore mine near Postmasburg in the Northern Cape.
Kolomela, which went into production in mid-2012, is Kumba Iron Ore’s newest mine, formerly known as Sishen South during its development phase.
Kumba awarded the contract to ACTOM Air Pollution Control in April 2013 as part of its Ramp Up Project currently under way to improve production output and efficiencies at the mine. The contract was a follow-up on the original dust extraction contract undertaken by the company in 2009 and involving installation of wet scrubbers on each of the crushing plants, the screening plant and the loadout station.
Raymond Hopkins, ACTOM Air Pollution Control’s Project Manager responsible for the latest contract, said it was awarded after Kumba engineers had identified a need to improve dust extraction efficiencies on the secondary and tertiary crushers with the installation of an additional scrubber on each. “We were responsible for the manufacture and the supply of the scrubbers, as well as for the civil design, electrical equipment and controls, but it was part of the contract conditions that installation be undertaken by Kumba Iron Ore under our supervision,” he stated, adding that the scrubbers were delivered on schedule in September/October 2013.
As with the scrubbers supplied under the original contract, the two scrubbers supplied under the latest contract have been designed to maintain emissions at under 30 mg/Nm3 in accordance with the applicable environmental regulations.
