Extraction of Metals: From Ores, Definition, Meaning, Examples

Jun 23, 2021  The steps depend on the type of ore, the reactivity of the metal, and the nature of impurities present in the ore. These processes involved in the extraction and refining of the metal are called metallurgy. The ores of most of the metals should be brought to the Earth’s surface for extracting metal from them.

Alloys and extraction of metals - VCE Chemistry

Metal alloys and extraction of metals. •By mixing a metal with other metals or some non metals, we can change its properties. This process is called alloying and the resulting metal is an alloy. •For example pure gold (24 carat) is a relatively soft element and is easily deformed. The alloy 18 carat gold is used in jewellery.
