Precious Metal Recovery ( Video )


Precious Metal Recovery refers to the reclaiming of precious metals from specific scrap materials. Many precious metal recovery services employ state of the art refining techniques, for extracting metals such as gold, silver and platinum etc.

These processes can extract precious non-ferrous-metals from industrial scraps, wires tubes and dishoarded bars. Recovery services are used in a variety of industries including, aerospace, jewelry, medical and the semi-conductor and printed circuit board industries.

These services may also include reducing the metal lots to assaying bars for evaluation, by utilizing thermal processes. Metal refining capabilities can include, melting and thermal reduction through incineration.

Recovery refers to the separation of precious metals from noble-metalliferous materials, some of these materials may include catalysts such as electronic assemblies or printed circuit boards. 

To isolate or remove the metals, procedures such as hydrolysis or pyrolysis are commonly employed. With hydrolysis, the noble-metalliferous materials can be dissolved in hydrochloric acid and chlorine gas solution, or dissolved in Aqua regia, which consists of hydrochloric acid and nitric acid. 

In the procedure known as pyrolysis the precious metals are removed by solidifying in a melt to become cinder, and then oxidized. Some metals may be reduced directly with a gas or salt or nitro hydrate connection.

This is followed by various cleaning stages or are recrystallized, and the metals can then be separated from the salt by calcination. These precious metal materials are first hydrolyzed and then thermally prepared (pyrolysed) thereafter. The recycling product is removed and put several times through the cycle.

Precious metal recovery services are companies that purchase materials such as printed circuit boards, old wires, and industrial scraps that contain various precious metals such as :

o Gold & Silver

o Platinum

o Nickel & Tin

o Rhodium

o Palladium

o Copper & Bronze

These materials are then put through various processes to extract the precious metals from them. This makes good economical and environmental sense.

These services may also include buying old jewelry, and other valuable scrap metals such as :

o Brass

o Copper

o Bronze

o Aluminium

o Phosphor Bronze

These metals can then be smelted down and reused, thus saving valuable resources.
