General Principles and Processes of Isolation of ,
The process of separating a metal from its ore is known as smelting Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique
GCSE CHEMISTRY - Extraction of Metals - What is a Metal ,
The method used to extract a metal from its ore depends on where the metal is in the reactivity seri Metals above Carbon in the Reactivity Seri A metal above carbon in the reactivity series (potassium, sodium, lithium, calcium, magnesium and aluminium) can be extracted by electrolysis
Lead is extracted from its ore by reduction with carbon Considerable effort has to be made to separate the lead ore from zinc or In recent years, lead has become one of most highly recycled materials in general use Uses of lead Over 80% of all lead produced ends up in lead-acid batteries, with lead metal as the cathode and lead,

Learn About the Properties and Applications of Platinum
Platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silver-like appearance, as well as in medical, electronic, and chemical applications due to its various and unique chemical and physical properti
the extraction of metals - an introduction This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis
Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metal-containing compound, and (3) reducing the ore to the metal Additional processes are sometimes required to improve the mechanical properties of the metal or increase its purity
