Dozens of Outotec technologies have become industry benchmarks, including its revolutionary flash smelting and flash converting technologies for sulphidic copper ore
- The majority of the world’s iron ore pellets, half of the world’s primary copper, and a third of the nickel sourced from sulphide ores are produced using Outotec processes
- Over 76% of Outotec’s technologies can be classified as environmental goods and services (EGS) under OECD criteria
- Key areas of expertise include concentration, filtration, solid-state material metallurgy, pyrometallurgy, hydrometallurgy, and gas handling. Outotec also has extensive know-how in material technology, plant and equipment engineering, equipment and process automation, and managing major international projects as turnkey deliveries
- Two in-house research centres, state-of-theart laboratories, and extensive test facilities are located in Finland and Germany.

Grinding processes typically consume large amounts of energy, making them the largest single cost item in mineral processing. Outotec’s latest solution to this challenge is the Turbo Pulp Lifter™ (TPL), designed to provide optimum grinding efficiency and maximum capacity, while using much less energy.
Conventional grinding mills waste massive amounts of energy, as only 5-10 % of the energy they consume is actually used to break up particles. Avoiding over-grinding, therefore, represents a major priority, and TPL technology achieves this by ensuring a very efficient transfer of material inside and outside the mill.
TPL allows product-size particles to pass more quickly through the discharge grate, reducing the amount of material in a mill and cutting the power it draws. This results in a lower proportional power requirement and substantial energy savings compared to a conventional mill.
Retrofitting an AG/SAG/Ball mill with TPL technology can make a big difference to plant efficiency, offering up to a 20% increase in mill capacity and around a 20% reduction in energy consumption per tonne.
One of the first sites to benefit from the new technology has been Cortez Gold Mines in Nevada, where the modernisation of the site’s SAG mill has improved throughput and overall reliability, and delivered major power savings, together with a valuable reduction in annual CO2 emissions.
