Over the last decade there has been increasing interest in bio-tank oxidation processes for the oxidation of minerals. So far, aerated stirred tank reactors have been used for these processes. From in house desk studies and experimental work caried out on pilot plant scale and full scale by Paques, it can be concluded that the CIRCOX ® air-lift loop reactor is a viable alternative to stirred tank reactors for the bio-oxidation of minerals. The main advantages of the CIRCOX ® air-lift loop reactor over the conventional stirred tank reactor are lower capital and operational expenditures.
