Environment - Sulfuric acid leaching

Health and safety issues are essential elements of Outotec leaching technologies. We ensure that our technologies are easy to control and have a low maintenance requirement.

Environmental awareness and protection are important features of all Outotec technologies. We make effective use of raw materials and aim to reduce water and energy consumption. We strive to provide environmentally sustainable precipitation processes with the minimal consumption of additive agents. The production of residues is minimized, and the residues that are unavoidable for the process are stable or re-usable. Consequently, environmental protection is an integrated feature of our technologies.

The operator’s safety is strictly observed from design phase forward. Safety issues with respect to operation, equipment, the environment and personnel are improved in an easy and convenient manner with the help of advanced automation.

In the equipment design phase, environmental aspects are also taken in consideration. For example, the energy efficient Outotec OKTOP® Reactor series 3000 impeller has been developed in order to cut down the mixing of energy consumption (patent pending). Another example of the environmental design principle is the new Outotec® Cooling Tower (patent pending), which it is estimated has emissions levels three times lower than a conventional cooling tower.

Emissions from the processes are estimated and minimized through equipment design and the strict estimation of required process components in order to minimize unnecessary discharges from the process. All the observed emission sources are directed to OKTOP® gas scrubber systems to minimize any emissions to the environment. 

Outotec offers you the Best Available Technology, complying with local environmental requirements and applicable legislation.
