We have been investigating the possibility of recovering vanadium and other metals from petroleum cokes, using chemical and microbially-assisted leaching techniques (Zajic et al., 1977, 1978). The cokes examined were derived from bitumen processed from the Athabasca oil sands in the province of Alberta Canada. These bituminous sands occupy a vast area and represent the largest deposit of vanadium in Canada. Vanadium is much in demand as an additive in high-strength low-alloy steels (Brown et al., 1974).
