By Dr. Franz Wolpers. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems. Mine trucks that weigh between 106 and 260 tons, and carry payloads from 136 to as much as 400 tons, transport these materials from the pit bottom ...
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, …
