Methods of extraction Many metals are found in the Earth's crust as or An ore is usually a compound of the metal mixed with impuriti When the metal is dug up, a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal, the more difficult it is to .
Types of copper ore: Sulfid Different methods are used to process copper sulfide ores depending on the concentration of copper within the ore — higher-concentrated ores can be separated via .
The basic extraction of ore deposits follows these steps: Prospecting or exploration to find and then define the extent and value of ore where it is located ("ore body") Conduct resource estimation to mathematically estimate the size and grade of the deposit; Conduct a pre-feasibility study to determine the theoretical economics of the ore deposit
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 Smelting methods range from the basic to the high-tech, and are applied to ,
Extraction of metals The process of extracting metal ores buried deep underground is called Mining The metal ores are found in the earth’s crust in varying abundance The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridg
Sep 19, 2014· How is platinum extracted from its ore 1 How is platinum extracted from its Ore? An ore is a naturally occurring mineral from which a pure metal can be extracted For Platinum, the two- chief minerals are sperrylite or platinum arsenide (PtAs2) and co-operate or platinum sulfide (Pts)
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 Details for the extraction of aluminium, copper, iron and titanium are .
of gold extraction for SSM Methods Borax was added to milled ore to reduce the melting point of gold to a level accessible to SSM The amount of gold captured, and the amount of mercury released into the environment, was compared to two common amalgamation methods: whole ore ,

Magnesium processing, preparation of magnesium ore for use in various products In its pure form, magnesium lacks sufficient strength for most structural applications However, the addition of alloying elements improves its properties to such an extent that both cast and wrought magnesium ,
Describe some of the extraction methods and identify different types of mining In order to use the resources at our disposal, we need to be able to get to them This section introduces the different techniques used to extract or remove these resourc
The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate or Chalcopyrite (also known as copper pyrites) and similar sulfide ores are ,
The small chemical differences caused by the lanthanide contraction are used in four different methods, described below Fractional crystallization and fractional precipitation are mainly historical methods; both were inefficient and labor intensive and have now been replaced by solvent extraction and ion exchange

Introduction to Iron Ore and Steel Smelting Processing Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter Here the ore is put into a blast furnace along with limestone and coke and subjected to hot .
May 22, 2009· Extraction of Iron Step1: Concentration The ore is crushed in crushers and is broken to small piec It is concentrated with gravity separation process in which it is washed with water to remove clay, sand, etc 8 Steps of Extraction Step1: Concentration Step2: Calcination The ore is then heated in absence of air (calcined)
Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds Even after extraction, the rough diamond is still far from being set in an engagement ring
The picture shown above is a gold-bearing ore Different methods are used to extract different metals For instance, common metals like iron are smelted using carbon as a reducing agent Few metals, , Extraction of Metals , Calcination is a process where the ore is converted into oxides by heating strongly in the presence of excess air
Ore is rock that contains economic amounts of a particular element, eg gold ore, iron ore, molybdenum ore, or praseodimium ore In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock The metals in ore can occur in many different minerals (compounds) in the rock As an example, copper occurs in more than 50 minerals
