Sep 01, 2008 Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (waste-to-ore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining throughout the country.

Recycling one tonne of steel saves 1100 kg of iron ore, 630 kg of coal and 55 kg of limestone. Recycling one tonne of steel saves 642 kWh of energy, 1.8 barrels (287 litres) of oil and 2.3 cubic metres of landfill space. Every tonne of steel made from recycled scrap saves enough energy to power four homes for a whole year.

Vilela et al. analyzed the possibility of partially substituting the soil from the cement soil bricks with up to 40% iron ore mining waste. The density of the samples at 28 days varied between 1670 and 1750 (kgm −3 ), with a figure 5% higher in the case of mixture with 40% addition of mining waste compared with reference.

The recycling of aluminum uses only 5% of the energy used in its extraction from its ore which uses a small voltage but a large current. In fact some countries really encourage recycling by having separate sections in their public waste containers. One for waste, one for cans and other metal products, and another for paper products.

MoreIn a method of recycling iron and steel industry waste (1-1, 1-2) by processing the waste (1-1, 1-2) as an object substance by the use of a rotary kiln (7), the object substance is changed into a valuable material while the object substance travels within the rotary kiln (7) from an upstream side to a downstream side. The object substance is heated on the upstream side of the rotary
