Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being,Mineral Jig Concentrators for Ore Processing & Separation,,Mineral jigs are a type of mining equipment, also referred to as gravity concentrators or jig concentrators, that are used in operations to separate different ore materials based on their densities…

How iron is made - material, manufacture, making, history,

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.Process for the direct reduction of iron ore to steel,,10-06-1975· More particularly, it pertains to a process for the direct reduction of iron ore to iron metal with hydrogen and carbon monoxide in a fluidized bed by a continuous procedure employing (1) a gas generator-chemical separation plant for the production of CO and/or H 2 to be used in the fluidized bed for iron ore reduction and (2) a steel making furnace for converting the iron metal to steel.Geology, Prospecting and Exploration for Iron Ore,Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust. Before the heavy investments required to set up a mining operation is done, the mining organization is to ensure that the deposit is economically viable and it has quantities of ore that will ensure ore production over a sufficiently long period of time.
