Mopani Copper Mine

After the successful completion of Lubambe Mine's Concentrator Civil works in Chililabombwe, Zambia, WBHO Zambia was in November 2012 awarded the civil works of the acid plant and gas cleaning plant for Mopani copper mines in Mufulira. Mufulira is a Copperbelt town situated 40km from Kitwe and 60km from Chingola. The first phase of the project was to construct the foundation for the converter, 6 heat exchangers, 3 acid towers, two 21m diameter acid tanks with containment area, and stack. In the month of January 2013, the works was extended with some more foundations for the gas cleaning area, cooling towers for contact sections and gas cleaning area, foundations for the pipe racks, duct supports, pipe and cable supports and 2 MCC rooms with all the brickwork and foundations.

PROGRESS
We are progressing well with the contract and will complete it in the next few months. It has been an incredible journey from an international expat team that includes no less than 9 different nationalities. The $36 million project funded by Millennium Challenge Account (MCA) includes 2 bridges, a concrete spillway, pump house, earth dam and a new surfaced road. We are in talks with MCA for further work in the Nacala area, a true testament to the quality of work our WBHO team has produced.

This Northern Mozambican project has had more than its fair share of challenges but the team has taken them in their stride, growing in confidence after every success.
