The process plant is to be located immediately adjacent the Blackard Pit.
- The basic processes include: primary crushing, comprising feed bin, apron feeder, crusher and dust suppression, grinding in a single stage SAG mill and classification in cyclones, optional stockpiling of primary crushed or to de-couple the grinding and flotation processes for the crushing operations, rougher and scavenger flotations, rougher concentrate regrinding to improve final concentrate grade, two stages of cleaner flotation, concentrate thickening and filtration and filter cake storage before transportation, tailings thickening and disposal storage facility and reagents preparation and services.
- The process plant has been designed to treat approximately 3 Mtpa of sulphide feed, as this will be the case for the initial 4 years of production.
- Following this, the processing plant may require adaptation to process oxide ores, as the style of ore mineralisation vary.
- These throughputs are based on a 24 hour per day, 7 days per week operations.
- The flotation concentrate would be saleable for smelter feed.
- The proposed process plant comprises the following: Run of Mine (ROM) ore bin fed by either a front end loader or by trucks direct tipping ore, grizzly feeder to remove fines less than 150mm, conveyor feeding combined grizzly and crusher products to the mill, a SAG mill with single 3 MW drives, a ball miss with single 3MW drive, two sets of rougher/scavenger flotation cells (2x7x160 cubic metres), concentrate regrind mill with 550kW drive, cleaner flotation cells (6x50 cubic metres cells), recleaner flotation (4x20 cubic metres cells), concentrate thickening and filtration, reagents, air and water services and pumps, service cranes and hoists.
-
Plant to be upgraded to 5Mtpa utilising a blend of 60% soft native copper ores & 40% harder sulphide ores..
