Chapter Open Pit Mining
boundary. Open pit mining is used for the extraction of both metallic and nonme-tallic ores. Open pit mining is considered different from quarrying in the sense that it selectively extracts ore rather than an aggregate or a dimensional stone product. Open pit mining is applied todisseminated ore bodies or steeply dipping veins or
Iron Ore Mining – The process of iron ore mining
Mining iron ore is a physically and chemically demanding process that takes place in remote locations around the world. The process begins with exploration, which can be done through surface or underground methods. Once a deposit is discovered, mining can begin. Open-Pit Mining. Open-pit mining is the most common method used to extract iron ore.
