Tenke Fungurume Mining in the DRC, one of the world’s largest producers of copper and cobalt, which awarded John Thompson Air Pollution Control a contract on the recommendation of Hatch Goba, is nearly complete.
Hatch Goba, local subsidiary of the international Hatch engineering and project management group which serves the mining, metallurgical, energy and infrastructure sectors, made the recommendation on the basis of John Thompson Air Pollution Control’s (APC’s) longstanding track record as a provider of dust control and air-cleaning solutions for large mining and industrial installations and its extensive expertise in the design and provision of reverse-pulse bag filter systems.
Tenke Fungurume Mining, which commenced copper production in 2009, is located about 175 km north-west of Lubumbashi in Katanga Province.
The multi-million rand fast-track dust control and collection contract, awarded to John Thompson APC in December 2014 for completion at the end of May this year, is for the design, manufacture and supply – including delivery to site – of three reverse-pulse filter baghouses to be installed in the mine’s second sulphuric acid plant currently under construction as an extension to the existing ore processing plant.
All the bag filters will incorporate envelope bags and the system will comprise:
- A 15 000 m3/h bag filter and associated ducting for capture of sulphur dust in bulk bags, which are broken by specially designed hoppers. The collected dust is returned to the sulphur storage silo feed conveyor.
- A 1 000 m3/h capacity bag filter is mounted onto the sulphur silo to vent the dust generated by the feed to the silo.
- Another 1 000 m3/h capacity bag filter is mounted on a bag-breaking unit which collects hydrated lime dust supplied in bags, which is in turn fed into a hydrated lime storage silo.
John Thompson APC – formerly ACTOM APC – is a business unit of John Thompson, the ACTOM group’s Power division.
