Designed to meet a throughput of 16 tons per hour, the plant is expected to support wolframite recovery of 82.8%. It will be built in Johannesburg by Appropriate Process Technologies.
The modules will be containerized and trucked to site where it is expected that the process plant will commence operations by mid-2015.
Premier African Minerals CEO George Roach said: "Confirming this order is a further step in the process of re-opening the RHA mine."
Valued at around $2.2m, the cost of the plant will be paid in two tranches, including $688,016 already paid and the balance of $375,185 to be paid on or before 15 January 2015.
The company said: "Premier’s spend to date, inclusive of exploration and development costs is secured under a loan account with RHA.
"In the event that RHA is reliant on Premier to secure the required finance, then RHA is obliged to meet the cost of that finance."
