Extraction: An ore has to be changed chemically into the metal This process is called reduction How this is done, and how much it costs, depends upon the metal's reactivity see reactivity properties In general, the more reactive the metal, the harder it is to extract it from its ore

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts

This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using Extracting copper from its ores The method used to extract copper from its ores depends on the nature of

Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors

Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores

Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75 purity In many stainless steel applications, 75 pure nickel can be used without further purification, depending on the composition of

Jul 28, 2012 Steps involved in Extraction of metals Do you know that metals we used in daily life like aluminium, copper etc are extracted? There are different steps involved in extraction of metals First of all, ores are crushed into a fine powder in big jaw crushers and ball mills This method is called pulverization 2 Concentration Dressing of

There are 3 main methods of extracting metals from their ore They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal Extraction using carbon Metals such as zinc, iron and copper are present in ores as their oxides Each of these oxides is heated with carbon

Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores Very few metals such as the noble metals, i e , Gold, Silver, and Platinum etc are present in their original metallic forms in nature
