Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Sanders and Shaw (1988) used this method to investigate causal factors in underground mining. They conducted independent investigations of 338 accidents at 20 mines. The investigations resulted in detailed descriptions of each accident, including interviews with employees and a study of the worksite and equipment. The methodology was
· 2. Mining Methods • Coal is mined by two main methods - surface or 'opencast' mining and 'underground' mining. • The choice of method is largely determined by the depth, geology of the coal deposit and other factors. • The majority of the world's coal production is coming from Opencast mines. • This scenario is same in India also.
· More specifically, mining is used to extract non-renewable resources like fossil fuels, minerals and even water. There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit's location below or on the Earth's surface and the capacity …
