|
Outotec has been building reactors for hydrometallurgical applications for decades. We have been so successful due to our reactor technology being integrated into process and equipment design, giving us the confidence to assure you that the process' effectiveness is optimized. Our solutions have always been aimed at optimizing metallurgical results and secure operation. At Outotec, reactor design begins with managing the chemistry and extracting the rate limiting factors. Hence, a technical validation is performed in the laboratory in order to check whether or not the rate limiting factors were set accurately. Upon achieving certainty in this respect, the design is optimized on a larger scale. It is vital at this stage that the reactor remain fully operational despite its greater size. Lastly, a financial validation is performed to ensure that the technology is viable for the project. Our mastery of the entire cycle is what provides us with the core competencies to offer you an unmatched solution which is also the most economical. |

Outotec reactors
Outotec's comprehensive dedication to reactor design development has led to outstanding results, in the creation of the OKTOP™ reactor family. Outotec's commitment to providing its customers with the most stable and reliable production line can be seen in its reactor know-how. Our atmospheric direct leaching reactor, OKTOP™ DDT, is a prime example of our continuous reactor development.
The basic idea behind OKTOP™ DDT is to achieve the thorough dispersion of oxygen and slurry required to obtain optimum leaching results. A sufficient oxidation rate is achieved through radial blades beneath the pump turbine. OKTOP™ DDT has an effective volume of 900m³ and turbulence is concentrated in the bottom of the reactor, which is required for the dispersion of solid materials. All in all, OKTOP™ DDT has been designed and proven to provide the optimum, reliable direct leaching performance.
Cooling towers
Outotec has developed a new cooling geometry in its cooling towers by applying horizontal gas flow exit based on computational fluid dynamics (CFD). This new cooling tower has a unique top structure, which enhances effective cooling. The advantage of this novel technology lies in its uniform heat transfer, maintaining an even temperature and dispersion within the towers. Since the related emissions are therefore lower than in a conventional cooling tower, the impact on the environment is diminished. Furthermore, the cooling effectiveness allows for a more compact tower size. Housekeeping is easy due to the structure of the tower.

Thickeners
Outotec's exceptional SUPAFLO® thickener and clarifier family play an important role in the zinc process. Outotec's know-how results in special attention being paid to the engineering design of feedwells, rake profiles, drive systems and control strategies. High reliability and low capital costs are just a few of the advantages that these provide.
Scrubbers
Outotec's scrubbers are an integrated solution for cleaning reactor off-gases. Various designs have been invented for specific offgases in the zinc process. Tailoring the scrubbers to obtain an optimal solution forms one of the main components of this service.
Flotation cell
Outotec's world-leading flotation technology provides the means to remove sulfur and sulfides from the zinc process in order to produce suitable lead/silver products, which can be further processed in the lead smelter. In addition, we offer tailored flotation cells suitable for zinc refineries. At Outotec, we provide the required testing to determine the size of flotation cell and froth recovery arrangement fitting your plant. This enables compact, economical and efficient plant design.
