The grinding lines delivered to both sites will be identical systems consisting of the company's Premier ball mills and its Vertimill VTM-3000 stirred mills, said the company.
The deliveries of the grinding lines, which will have a capacity of 400tph, is expected to take place in January 2022.
"We are excited that Mapa has chosen us to deliver the key equipment for the expansion of these two projects in Liberia and Burkina Faso. Previously, we have delivered the key crushing, screening and grinding equipment to these two mines," says Mert Katkay, Head of Minerals Sales for Metso Outotec in the Middle East and Turkey.
According to Metso Outotec, its Vertimill provides the lowest total cost of ownership compared to other grinding mills in many applications due to its high energy efficiency, lower media consumption, low installation cost and minimal liner wear and maintenance.
The mills can handle feed sizes up to 6mm and grind to products less than 20 microns.
Vertimill sizes range from 11 KiloWatts to 3,352kW.
