what are the by products of using aluminium through mining

Types of Pollution Generated by Gold Mining

Types of Pollution Generated by Gold Mining Frequently, valuable ores run through rocks containing sulfides, and exposing this rock creates sulfuric acid. Washing these toxic byproducts away results in a semi-solid slurry called "tailings" that can contaminate the soil it comes in contact with.

Chem4Kids: Aluminum: General Info and Everyday Items

When aluminum is combined with other metals, it becomes very strong. It is so strong that engineers use it to build planes and ships. Did you know that there is even a type of plastic that has aluminum inside? Even though humans have been using the metal for thousands of years, it was not until 1807 that Davy named the metal.

Environmental Risks of Mining

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Iceland: Mining, Minerals and Fuel Resources

12-9-2012Iceland has an abundant source of geothermal power, but limited mineral and metals reserves. The mining industry does not play an important role in the country's economy and the economy is more dependent on its fishing industry. However, the abundance of geothermal power has attracted foreign investments to the aluminum sector recently.

Advantages Disadvantages of Recycling Metal

Aluminum, steel and other metals need to be manually separated from other recyclable material such as plastic and paper, according to Waste Care. Metals, especially aluminum, tend to degrade after each reuse cycle, so products using recycled metals can vary in quality, but most metals never reach a point where they are no longer recyclable.

Copper

Acidified water is sprayed onto copper-mining wastes, which contain low levels of copper. As the water trickles down through the crushed rock, the bacterium Thiobadllus ferrooxidans, which thrives in the presence of acid and sulfur, breaks down the iron sulfides in the rock and converts iron(ll) to iron(lll) ions.
