Thus, this review presents the ability of catalytic ceramic filters to boost energy efficiency by converting unwanted byproducts while simultaneously eliminating PM in a single unit and is shownIron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources. For instance, about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China. Iron ore tailings can be recycled as functional materials because these Recycling of iron ore tailings into magnetic nanoparticles

Ideally, a filtration system should enable achieving low moisture content of the final product, high productivity and would present low energy consumption. One of the greatest advances in this field in the minerals industry in recent years has been the introduction of ceramic filters (OUTOTEC, 2013, Smith et al., 2018).The common vanadium ores are vanadinite, patronite (vanadium sulfide, VS 4), and carnotite (potassium uranyl vanadate, K 2 (UO 2) 2 (VO 4) 2). Vanadium is also abundant in Venezuelan oil, to the Vanadium Elements RSC Education
