Increase reliability and plant availability even in the harshest environments with Outotec's carbon scrap recycling plants for aluminum smelters. We provide complete recycling plant solutions for butts and green scrap processing, as well as plant upgrades for existing facilities. Enables a high crushing ratio and lower CAPEX with a two-step screening and crushing circuit Can be delivered worldwide as a complete package: our capabilities include everything from conceptual engineering studies to full engineering, procurement, and construction services

Achieve excellent reliability and availability with Outotec's paste plant. The solutions, originally developed in the 1960s, are based on efficient anode-forming technology that uses vibrating compactors to produce high-quality anodes with consistent properties and low variability. As the leading supplier of anode vibrating compactors for the aluminum industry, we continually develop our technology to meet our your requirements. Offers high reliability and plant availability Produces high-quality anodes with consistent properties and low variability Provides in-house manufacturing capabilities for special green anode plant equipment, including preheating screws and anode vibro-compactors Minimizes environmental impact from dust, fumes, and noise

Achieve excellent performance with low energy consumption. Outotec alumina calcination plants are based on Circulating Fluid Bed (CFB) technology, which we introduced to the alumina industry in 1970. Since then we have installed more than 60 calciners globally and our innovative technologies continue to be used worldwide. • Offers extremely stable operation • Boasts low energy consumption and very low pollution levels • Has a small footprint • Provides high plant flexibility in terms of partial load and overload behavior

Increase efficiency and performance of your grinding circuit. Outotec’s ACT grinding optimization system – with the RockSense on-belt rock size analyzer, MillSense charge analyzer, and PSI particle size analyzer – gives you a complete solution for optimizing your entire grinding circuit. The system stabilizes the process, maximizes throughput, improves control of particle size, and provides accurate on-line analyses of the most critical variables. Improved utilization of grinding capacity Maximized process throughput Reduced energy consumption Higher overall equipment efficiency A complete solution from one supplier

Choose a highly cost-effective and efficient zinc concentrate direct leaching solution. Outotec's zinc direct leaching process enables efficient zinc and by-product recovery from a wide range of primary zinc sulfides. Direct leaching requires no investment in a roaster or acid plant, so it is especially suitable for smaller plants and plant expansions. Recovers zinc as SHG ingots and by-products such as Cu, Cd, Co, Ni, In, Ga, and Ge Adapts to different feed qualities and by-product recovery demands Scales to a wide range of production capacities Enables efficient oxidation at low cost with specially designed reactors for atmospheric leaching Boasts a low CAPEX as no roaster or acid plant is needed

Collect the finest particles from electric furnace off-gas with the Outotec CO Gas Filter. This cassette-type CO gas filter enables the removal of even the smallest particles that pass through scrubbers, with collection efficiencies close to 100%. Our CO gas filter also allows you to utilize valuable cleaned carbon monoxide gas for demanding cogeneration applications. Enables extremely low emissions Lowers maintenance costs Operates indepently of variations in gas flow Enables utilization of CO gas in demanding cogeneration applications Increases CO gas utilization equipment availability Allows for increasing capacity through modular design Low pressure loss over the filter

Handle explosive gases in the safest possible manner. The Outotec Venturi Scrubber is a high-pressure scrubber that cleans electric furnace off-gas and effectively pressurizes the CO gas line. The efficient and secure operating principle is to both cool and clean the gas and to quench sparks from the furnace. In addition to minimizing air pollution, Outotec Venturi Scrubbers improve electric furnace operation and increase equipment availability. The scrubber is very simple to operate as it has no moving mechanical parts. Reduces emissions to surrounding atmosphere Operates reliably for low maintenance requirements and costs Effectively removes slurry Operates consistently even with variations in gas flow Enables safe CO gas handling due to overpressure operation
