JOHANNESBURG (miningweekly.com) – Johannesburg- and Sydney-listed Orion Minerals has continued its transition to mine developer and operator at the Prieska copper/zinc mine in South Africa’s Northern Cape. The mineral resource for the entire Okiep copper project has now increased to 12-million tonnes at 1.4% copper for 160 000 t of contained copper. However, opportunities exist to improve on the processing route for the supergene sulphide portions of the deposit. The metal vapour refining technology currently being tested on metal sulphide concentrates presents an opportunity to maximise metal recovery to high-value products. The Prieska mine has partnered with Power Plant Electrical Technologies for electrical specifications and electrical project management.
