Metso Outotec offers compact elution and gold room plant

Save energy, time and money with Metso Outotec’s modular elution and gold room plant.

Metso Outotec is introducing the compact Elution and Goldroom plant, a standardized solution for the forming of concentrated eluate to be processed for gold recovery by electrowinning. The innovative plant design is based on pre-engineered modules to reduce engineering, delivery and construction, as well as commissioning time and investment cost. It also provides the flexibility needed to meet the various process, layout, and regulatory requirements.

With the introduction of this plant, Metso Outotec now has the capability to deliver a full run-of-mine ore to doré process flowsheet.

The Elution and Goldroom plant can be delivered standalone or as part of a total gold process solution to enable onsite production of gold doré. Metso Outotec offers compact plant flowsheet designs based on ZADRA or AARL technologies. The Elution and Goldroom plant features a heat recovery circuit to minimize energy consumption and efficient carbon dewatering to maximize carbon regeneration and minimize energy losses.

The plant is available with four levels of automation – standard, upgraded, advanced, and premium – and can be controlled either from a standalone control room or via the plant’s DCS system.

Metso Outotec can dynamically model the plant’s acid wash, elution, and electrowinning circuits using its proprietary HSC Chemistry software.

Users can expect four key benefits: reduced cost and short lead time; ease of operation thanks to automation options; complete performance guarantee; and safe, efficient training via a virtual plant simulation.
