In recent years very little attention has been placed on the environmental impact of iron ore mining across the globe in terms of environmental pollution due to heavy metals compared to mines extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately percent of the ore extracted processed as waste disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. the impacts are often more
iron ore, one of the most abundant metals on earth, is the primary raw material used to make steel operations We work in about countries in mines, smelters and refineries, as well as in sales offices, data centres, research and development labsmar 04, 2020 mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. however, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
