Making products from recyclables results in energy savings. Recycled steel saves 60% production energy, recycled newspaper 40%, recycled plastics 70%, and recycled glass 40%. Using scrap steel instead of ore to make new steel takes 40% less water and creates 97% less mining waste. How does recycling benefit the economy?

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use. The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore ...

Mining Techniques. Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
