Embedded in West Africa
With West Africa’s mining industry evolving rapidly, Weir has built a solid footprint of local expertise, capability and capacity in the region to serve customers’ increasing demand for efficiency, sustainability and technological integration.
“We have proactively invested in training and skills development to build talent to meet operational demands in the region,” Andrew Ayirebi, Weir’s Regional Manager for West Africa, explains. “We prioritise developing our people who are key to delivering sustainable value. Our operations in Ghana and Senegal are fully managed by local teams, with an active presence in Mali, Côte d’Ivoire and Nigeria.”
Wide range of commodities
With its focus on customised solutions, Weir supports a wide range of commodities mined in West Africa including gold, bauxite, iron ore and lithium. The company is strategically transitioning to configured-to-order (CTO) systems to further reduce lead times while improving efficiency and stability of supply chains.
“We partner with customers throughout the mining lifecycle, supporting our sustainable mining and processing solutions with on-site services and fast response times,” Andrew adds. He points to the wide range of operational areas where Weir adds value which includes comminution, classification, slurry handling and dewatering.
Intensive steps
“In terms of comminution, grinding is one of the most energy intensive steps in mining. Our Enduron high-pressure grinding roll (HPGR) technology reduces energy consumption in comminution applications, saving up to 40% in energy consumption compared to traditional SAG mill technology.”
At Endeavour’s Lafigué open pit gold mine in north-central Côte d’Ivoire, for instance, Weir provided its HPGR technology to save energy and reduce the carbon footprint , alongside consuming less grinding media to achieve lower operating costs and ensure a more consistent throughput.
Energy savings
The Enduron HPGR has delivered an operating availability of over 97%, and will enable the mine to achieve US$2,6 million in energy savings each year. This equates to avoiding the emission of 18 500 tonnes of CO2 emissions per year.
Investing heavily in R&D, Weir also enhances equipment with its WRT which reduces energy usage in its Warman pumping systems, for instance. The GEHO range of positive displacement pumps, which transport high density slurries over long distances, also minimise energy consumption.
Downstream processes
Weir’s classification solutions ensure optimal particle size distribution to maximise the efficiency of downstream processes. The company also leverages digital technology to further enhance the value of its equipment, by applying its NEXT intelligent solutions.
“This gives mining operators real-time insights into equipment condition and performance,” Andrew concludes. “Our acquisition of digital mining solutions leader Micromine earlier this year further strengthens our ability to optimise customers’ operations.”
