Pumping abrasive slurry A vanadium facility, located in South Africa is winning vanadium from titaniferous magnetite. The titaniferous magnetite is processed in various stages, using a.o. precipitation tanks and various positive displacement and transfer pumps. Vanadium occurs naturally in about 65 different minerals and in fossil fuel deposits. It is produced from steel smelter slag, the flue dust of heavy oil, or as a byproduct of uranium mining. It is mainly used to produce specialty steel alloys such as high speed tool steels. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. Magnetite and vanadium are of a very abrasive composition causing problems in the lifetime of process materials such as in wetted parts sections of pumps. All vana
