IMMOBILIZED BIOREACTOR SYSTEM FOR SULPHIDIC MINERALS AND OTHER PARTICULATE SOLIDS

摘要

A method and apparatus for bioprocessing particles wherein particles are entrapped a porous material and have biologically active microorganisms on their surfaces. A liquid (carrying oxygen and/or nutrients for said microorganisms) is passed through the entrapped particles and microorganisms and microorganisms are active to breakdown said particles. After a suitable period of time the particles are removed from the matri x.
