Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.
Landfill Mining: Goldmine or Minefield? As societies move waste management practices up the hierarchy towards recovery, recycling and reuse, we are still left with the environmental legacy associated with the historic use of landfill.
Apr 08, 2019· The short answer to the question is: yes.there is profit in recycling gold (and other precious metals) from electronic devices. The longer answer is that it definitely requires resources to get this resource (the old adage, it takes money to make ...
In some other cases, for example, biomining gold and some other precious metals, microorganisms are used to remove minerals that occlude target metals which are solubilized in a second process ( by extracting with cyanide or thiosulfate in the case of gold; ). In such cases, the biological pretreatment stage is referred to as biooxidation.

Among the precious metals, platinum is seen as more valuable than gold and silver. It closely has the same density as gold, and the same malleable and ductile properties of gold. It is as resistant to corrosion as gold. However, what sets platinum apart is its rarity. The ratio, in terms of availability, of platinum to gold is 1:15.
