Karara Mining Limited has signed a contract with Metso Outotec for the design of a tailings filtration plant expansion project at its iron ore mine in Western Australia.
The contract includes the delivery of key filtration and materials handling equipment and associated services.
The parties did not disclose the value of the contract but the typical cost for an order like this is in the range of €15M-€20M depending on the scope of delivery.
Karara produces a premium, high-grade (65%-68% Fe) magnetite concentrate at a design production rate of 8 Mtpa. With this expansion, the operation will increase the current tailings filtration capacity from 30 kt/day to over 45 kt/day enabling safe and sustainable storage of the process mine waste, with improved utilisation and recovery of water.
Metso Outotec’s scope in this expansion will include the Larox FFP3512 as primary filtration equipment, materials handling conveyor systems and peripheral items.
Additionally, spare parts and supervisory services will be supplied to support commissioning and plant ramp up. Delivery will take place during 2022, and the plant is expected to start production in late Q4 2022.
“The Karara mine represents one of the largest filtered tailings facilities in the world,” said Kai Rönnberg, Metso Outotec vice president for minerals sales in the Asia Pacific region.
“We are very proud that Karara Mining Limited has chosen Metso Outotec to deliver the plant design and key equipment in this expansion project.
“This is a continuation of earlier delivered proprietary key process equipment and long-term onsite maintenance service agreements.”
