:: ABB Gearless Mill Drive & Digital Services Help Increase Production by 50% at Kinross Tasiast

 

Kinross Gold significantly expanded production capacity at Tasiast gold mine in Mauritania, adding incremental crushing and grinding capacity to the existing carbon-in-leach (CIL) circuit. The company selected ABB’s 26 MW gearless mill drive system (GMD) for the mine’s 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service agreement (LTSA). This is expected to reduce operating costs, improve process throughput and reliability while saving energy and keep equipment in top form.

The Tasiast gold mine is an opencast operation located in northwestern Mauritania on the West coast of Africa, approximately 300 km north of the capital city of Nouakchott. It is owned and operated by Kinross Gold (Kinross), a Canadian-based senior gold mining company with mines and projects in the US, Brazil, Russia, Mauritania, Chile and Ghana. Kinross’ focus is on delivering value based on the core principles of operational excellence, balance sheet strength, disciplined growth and responsible mining. The company recently initiated a phased expansion of its operations at Tasiast. Phase One significantly expanded production capacity and is also expected to reduce operating costs.

On August 1, 2018, Kinross announced that construction was complete and that first ore had gone through the semi-autogenous grinding (SAG) mill. Since then, the mill throughput increased from 8,000 t,d to 12,000 t/d, representing a 50% increase. The mine estimates average annual production of gold to be 409,000 oz/yr through 2027.
