The mining process of iron sand involves complicated mining stages, and sometimes backward mining technology may do a great harm to the environment. Here are the advanced iron sand mining stages. Firstly, the raw materials should be extracted from the iron mine, and then it should be crushed for primary crushing.
Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds.Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.Sand can replace eroded coastline.
Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off-site. (Some mines sort and dry sand on-site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process-water pond.

The char is burnt at a predetermined rate by the air blown in through the fans mounted on the kiln shell. The hot gases generated during combustion raise the temperature of the kiln refractory lining (bricks) and as the kiln rotates (at one revolution every two minutes), the bed of iron sand, char and limestone slides over hot refractory.
Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.
