Plasma technology retrieves precious metals from e-waste

Plasma technology retrieves precious metals from e-waste: Tetronics International is aiming to address the growing issue of electronic waste by using plasma to recover precious metals from the debris.



 Plasma technology retrieves precious metals from e-waste






Tetronics’ clean plasma technology turns old electronic devices into
value by extracting precious metals such as gold, silver, copper and tin
whilst eliminating the hazardous materials.



The heat and ultraviolet light properties of plasma, an ionised or
electrically charged gas, are designed to smelt and separate precious
metals in a furnace, whilst destroying any harmful elements. A
non-hazardous vitrified material is left behind, which the company calls
Plasmarok and which can be used as a building material for the
construction industry.




Very interesting technology,

Gold prices likely to rise by year-end: analysts - Economy






Maybe time to start thinking of early Christmas presents?

Representatives of gold trading companies said this was the best time to buy gold.

Global
gold prices have been falling for months especially with the relentless
appreciation of the US dollar. Gold and the greenback traditionally
have an inverse correlation.

However,
the recent economic and political instability around the world could
put paid to this, and the precious metal could resume its role as a safe
haven, which would cause its price to rise strongly, the
representatives said.

New Way to target


 I'd love to know what chemicals they are using...

Researchers at the University of Edinburgh are developing a new compound to extract gold from used electronics. Around 7% of the world’s gold is inside e-scrap, of which less than one-third is currently salvaged, according to project leader Professor Jason Love.

One tonne of gold ore contains around up to 5 grams of pure gold. However, a tonne of discarded mobile phones easily holds 300 grams of the valuable metal, Love says. The chemical reagent pioneered by in Edinburgh effectively recovers ‘a very high purity of gold’ from various types of discarded electronics.

First, the researchers place the printed circuit boards in a mild acid to dissolve metallic parts. An oily liquid containing the new reagent is then added, which allows gold to be extracted selectively from the complex mixture of metals found inside electronics.

Any ideas for this please comment  - have a great day :-)

STEM education teaches students about metal work

STEM education teaches students about metal work: At Green Magnet Academy, there are future blacksmiths and welders in the making. The fourth grade class took a field trip to a local metal fabrication shop on Thursday.
