For example, assume that in 2015 a company paid $ 650,000 for a tract of land containing ore deposits. The company spent $ 100,000 in exploration costs. The results indicated that approximately 900,000 tons of ore can be removed economically from the land, after which the land will be worth $50,000.
• The best scrap substitute with respect to energy usage is liquid pig iron or hot metal. • Gangue and ash in ore and coal increase minimum ironmaking energy by about 6%. • In BOF steelmaking, the energy to produce steel is less than the energy to produce iron because scrap is melted in the process.

Jun 25, 2016· The largest energy-consuming process is ironmaking in the blast furnace, where iron ore is reduced using coke to make liquid pig iron. The energy for this chemical transformation is carried forward in the iron and steel streams in the subsequent processes, as is a small contribution of thermal energy of the liquid metal.
Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from
