During this period he was Technical Adviser to Rand Mines Limited on a project to construct a commercial plant to produce chromium steel from Bushveld ore. The Evraz Highveld Steel & Vanadium (EHSV) process flowsheet was developed in the early 1960s, based on Bleloch's 1949 work. He showed that magnetite ore from the Bushveld Igneous Complex could be smelted using a submerged-arc furnace while controlling carbon addition.[6]
