    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 asUseful metals are often chemically combined with other substances forming ores A metal ore is a rock that contains enough of the metal to make it worthwhile extracting They have to be extracted from their ores through processes such as electrolysis , using a blastExtracting Metals | Edexcel GCSE Chemistry Revision NotesA metal ore is a rock that contains enough of the metal to make it worthwhile extracting They have to be extracted from their ores through processes such as electrolysis , using a blast furnace or by reacting with more reactive materialExtraction of Metals & Reduction | AQA GCSE Chemistry

  • GCSE CHEMISTRY Extraction of Metals What is a Metal

    for economic extraction is called a metal ore Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal The most common metal ores are oxides and sulfides Sulfides are the oldest ores, formed in the Earth's history when there was a lot of sulfur from volcanic activity Oxides formed later when09/10/2020· The science of extracting metals from their ores and utilizing them for various useful purposes is called metallurgy The nature and properties of metals make its extraction difficult by using single method Thus, it is important to know that no single process can be used for extraction of all the metals The process to be used may differ from metal to metal However, some steps are commonExtraction of Metals (Metallurgy) – Overall Science22/07/2021· Extracting Metals from Ores I am a passionate educator and love to help and support other teachers!
