An ore is usually a compound of the metal mixed with impurities. 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 extract from its compound.
The ELIXORE range is well proven among metal mining customers in Australia, Myanmar, China, South Africa and USA. The advantages of TOTAL ELIXORE Diluents Optimize Extraction Efficiency and Cost. Stable solvent against oxidation; Good solubility with extractant; Longer recycling service life than high aromatic solvents
metal must also be capable of backextraction with another suitable aqueous phase. The organic and aqueous phases used must be com patible with process, health and safety, and cost considerations. The ability of the solvent to extract the metal is defined by a distribution coefficient, D, where
Extraction of Metals
To obtain the metal its ore, a reducing agent is used to remove the oxygen, in a reduction reaction.
Examples of some reducing agents;
Coke (an impure form of carbon)
Hydrogen (made from methane and water)
A more reactive metal may be used.
Electrolysis can also be used for more reactive metals.

What Are the Advantages and Disadvantages of Recycling Metals? The advantages of recycling metals are that it is landfillfriendly, environmentally conservative and a bolster to the economy. The disadvantages of recycling metals are uncertain results, job requirements and toxic byproducts.
Extracting Raw Metal. Advantages: Raw metal can be a source of valuable revenue. It can be exported and sold to countries that consume metal the most, such as China and the United States. Extracting raw metal also creates jobs for a lot of people, so does processing, refining, and transporting metal. Get A .
But right now, the economic equation gives inexpensive iron and steel a huge advantage over these much more expensive alternatives. The only real problem with iron and steel is rust. Fortunately, you can control rust by painting, galvanizing, chrome plating or coating the iron with a sacial anode, which corrodes faster than the stronger metal. Think of this last option as hiring a bodyguard to take a bullet .

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Advantages over NonSolid Based Technologies. Solvent Extraction: Instead of putting the metal binding group on a solid material, Solvent Extraction puts the binding groups in a liquid material, specifically an oil layer, which pulls target metals from water into oil. While the dissolved ligands bind metals quickly because they are in...
