Impacts on the environment due to the extraction of iron from haematite does not only start during the extraction of iron from the ore - it starts when the raw materials are being mined and transported. The following are problems which arise from these processes: From mining and transporting of raw materials - Air pollution - Noise pollution
Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.
