Biological and Bacterial Oxidation

This process is a natural alternative to pressure oxidation for process ores containing sulfides. In essence, bacteria oxidize and break down the sulfide minerals, freeing the occluded metal and making it more amenable to leaching.

We can design a test program to obtain sufficient data for scale-up, as well as guarantee mass transfer in the full-scale tanks.

With A315 and A320 impellers, you can get up to 30% greater mass transfer than radial flow Rushton turbines at identical power levels and gas rates. The designs of these impellers are the result of our extensive experience in mass transfer and the fluid mechanics of mixing impellers. They are specifically designed for high gas applications that also need high flow characteristics, such as solid suspension.
