Copper mining. From ore to copper.
The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass.
Copper''s thermal conductivity, or capacity to conduct heat, is about 60 percent greater than that of aluminum, so copper can remove much more heat more quickly. The more heat removed from the processor, the more efficiently it will operate, with less potential for damage to other critical components.

What Is Diatomaceous Earth
Diatomaceous earth is consumed and enters the digestive system. It attacks parasites like bacteria and viruses as well as bigger parasites like ringworm and tapeworm. The sharp edges of diatomaceous earth then cut the exoskeletons of these animals, which kills them. They are then transported out of the body and removed permanently.

Copper, however, seems to have escaped the notice of chemophobes who have persecuted lead and mercury. Copper tarnish is composed of CuO, and the basic carbonate if moisture and air are present. It can be removed by solutions containing the ammonium ion, which forms the soluble ammonia complex. The commercial preparation Brasso is an example.

Copper | Geoscience Australia
Copper is the only naturally occurring metal other than gold that has a distinctive colour. Like gold and silver, copper is an excellent conductor of heat and electricity. It is also very malleable and ductile. Copper is also resistant to corrosion (it does not rust very easily). Copper is soft but tough.

The reason that earth/soil should never be relied upon as part of the ground fault return path is due to its high resistance. The resistance of earth is on the order of one billion times that of copper (according to IEEE standard 142 Section 2.2.8) and will only allow a few amperes (1-10) back to the source.
