Howden says it has successfully delivered the first phase of an 8 MW surface bulk air cooling plant for Roxgold’s Yaramoko gold mine in Burkina Faso.
The Yaramoko Mine Complex is in a remote region of Burkina Faso, 200 km southwest of Ouagadougou.
The cooling plant is designed to deliver a maximum of 190 cu.m/s of chilled downcast ventilation air, with the air cooled from a design ambient temperature of 25.8°C, down to 15°C.
The plant comprises an open-spray vertical bulk air cooler located on top of the shaft collar, centrifugal chillers and conventional cooling towers, Howden explained.
Plant design and construction were started at the beginning of 2020 during the early onset of the COVID-19 pandemic, and, despite a challenging environment, Howden successfully delivered the project’s first phase in May.
Howden said: “This latest project continues to positioning Howden as a process and system specialist to design, supply and install mine cooling systems. Howden has a technology-neutral approach whereby technology options are offered which best suits customer’s technical and commercial requirements.”
The Yaramoko Mine Complex, which consists of two underground operations, delivered production of 35,308 oz of gold in the March quarter, Roxgold reported in May.
