DRA paves the way for cutting-edge processing operations at Rosh Pinah

DRA Global is the trusted long-term partner of Trevali Mining Rosh Pinah at the Rosh Pinah zinc-lead mine in southern Nambia. The Group is undertaking the “Rosh Pinah 2.0 feasibility study” on the significant upgrade of the mine’s process plant to increase its throughput from 2 000 tonnes to 3 600 tonnes per day.

The feasibility study will lead the mine to optimise the process plant through the implementation of DRA’s advanced process control technology. “The process control technology will feed into a central data centre at the mine and will help to maintain consistent throughput and make the plant operation more efficient,” says DRA Senior Vice President of Projects JC Heslinga.

DRA Global has laid the foundation for the “Rosh Pinah 2.0 feasibility study” on the upgrade of the mine’s flotation plant by undertaking the conceptual study for the plant in 2018 and completing the pre-feasibility study for the project in 2020.

DRA has built a collaborative business relationship with Trevali Mining

Rosh Pinah over the past six years, starting with a study of the plant’s communition circuit in 2015, and progressing to the addition of regrind mills to two concentrate streams and replacement of the tailings pumping system. In 2019, DRA Global added a new zinc concentrate filter circuit to the plant which increased its capacity and improved the moisture levels of the final product.

“DRA is working as an integrated team with Trevali at the Rosh Pinah mine,” says Heslinga. “The ‘Rosh Pinah 2.0 feasibility study’ will be instrumental in transforming the process plant into a cutting-edge operation when it is delivered in 2021.”
