The test data generated were used to develop a conceptual flowsheet of a to recover, in order, cobalt, copper, nickel, cadmium, and . The conceptual flowsheet included: 1 sludge recycle to increase overall recoveries at a penalty of increased capital and operating costs 2 copper and cobalt recovery by co-extraction ...read more
The Zinc/lead processing plant is controlled by a Yokogawa Centum DCS. The mine also uses AXF flow meters, EJX pressure transmitters and analytical products. Snow Peak Mining Snow Peak Mining operates in Northern Queensland with 4 mines and three processing plants. The mines produce 40,000 tonnes of zinc and lead as well as 22,000 tonnes of copper.read more
The application of vibration milling in the flowsheet enables the L-M to be used in a single stage at temperatures below the melting point of elemental sulphur. Sulphur is agglomerated and screened, Fe 2 O 3 is filtered-off, and copper is obtained by electrolysis with the formation of sulphuric acid essential for leaching.read more
