Extraction of Metals. Industries extract metals from their ores. What are ores Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.

loys today. The observation that metals could be extracted from ores was vital to the development of metallurgy, because the number and supply of native metals was quite limited. Before metal-lurgy could emerge as an art or science, the an-cient metallurgists had to be aware that the sup-ply of raw materials was not limited to the native metals.

The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverization.

Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

Jul 10, 2021 Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70 of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores ones containing a high percentage of copper in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.
