Patent AT-E400529-T1: [Translated] METHOD FOR BIOLOGICALLY TREATING SOLID MATERIALS IN AN UNSTIRRED SURFACE BIOREACTOR
Description
A method of biotreating and recovering metal values from metal-bearing refractrory sulfide ore using a nonstirred surface bioreactor is provided. According to the method, the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 μm. A nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated coarse substrates into a tank so that the void volume of the reactor is greater than or equal to about 25%. The solid material is biotreated in the surface bioreactor until the undesired compound in the solid material is degraded to a desired concentration.
