By recycling copper instead of extracting it from mined copper ore we reduce CO₂ emissions by 65%. 60% produced since the 1900s is still in use. Facts: BIR. Recycling Aluminium (Al) uses 95% less energy than producing aluminium from mined bauxite. Recycling one tonne saves 14,000 kWh of energy - enough to meet the energy needs …

For e.g., if the grade of ore were 1% copper, 99% of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulphide or gold ores, often going over 50% or more. Less tailings are therefore produced in the iron ore mines.

gold uptake from 96.5 % (by ICP-MS) at 5.0 ppm HAuCl 4 to 83.3 % at 1.0 ppm, with 24.7 % uptake seen at 0.1 ppm (Table S1, Figure S2). It is therefore evident that while this method is effective for recovering low concentrations of gold from solutions relevant to e-waste recycling it is not usable for trace gold uptake. The gold-containing ...

It contributes to the Circular Economy, avoiding landfill, as well as saving the destruction of natural habitats caused by the mining of metal ore. Recycling one tonne of steel can save one and half tonnes of iron ore from being mined. Iron is a metal, but steel is a man-made alloy. Steel is made by mixing iron and carbon together.

For example, recycling a ton of steel conserves 2,500 lbs of iron ore, 1,400 lbs of coal, and 120 lbs of limestone, says the American Iron and Steel Institute. Not to mention it saves enough electricity to power 18 million s for a year. On the other hand, recovering a ton of aluminum cans saves 21,000-kilowatt hours.
