Metso Outotec has been awarded what it says is a major contract for the delivery of sustainable tailings filtration technology to PT Huafei Nickel Cobalt’s greenfield laterite nickel ore project in Indonesia.

Metso Outotec’s scope of delivery consists of the engineering, manufacturing and supply of the Planet Positive Larox® FFP3512 filters, as well as installation and commissioning advisory services and spare parts.

The fully automatic fast-opening filter press (FFP) combines the benefits of membrane technology and sidebar design with high mechanical and process performance, providing safe and sustainable high-volume dewatering of tailings with low operating and life cycle costs, Metso Outotec said.

The hydrometallurgical plant has a targeted annual output of 120,000 t of nickel metal and is expected to be in operation during the June quarter of 2023.

Metso Outotec’s Planet Positive portfolio, which the Larox FFP3512 filters are a part of, focuses on the most environmentally efficient technologies – of which there are more than 100 – in the company’s current portfolio, responding to the sustainability requirements of its customers. The customer requirements relate to energy or water efficiency, reduction of emissions, circularity and safety, Metso Outotec says.

Jussi Venäläinen, Vice President, Filtration business line at Metso Outotec, said: “For our customer, the key criterion for selecting Metso Outotec’s filtration technology was safe and sustainable tailings processing with proven service capability. In addition, we were able to meet the customer’s wish for a quick delivery time.

“We are very pleased to have been chosen as the solution supplier, and we look forward to working together with our customer on this important project.”

Metso Outotec’s filtration product portfolio is the largest in the field and the energy, emission and water efficiency is in a league of its own, the company said. It has carried out over 14,000 filtration tests and delivered more than 5,000 filters for various applications worldwide. Most of the filters are sold under the Larox product name along with Metso Outotec corporate branding. Metso Outotec also accommodates all filtration-related service and spare parts needs through its global service network.

The value of the order is over €30 million ($33 million), and it has been booked in Minerals’ Q1 (March quarter) 2022 orders received.
