Copper Toxicity Copper Toxicity

Copper toxicity, though sharing some similarities with Wilson''s Disease, is different in that the latter is an inherited & rare genetic disorder which, like copper toxicity, causes copper to collect in the liver, brain and other body tissues, but has a more dire prognosis than copper toxicity, and for which a different treatment approach is

Copper Wikipedia

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.

From Ore to Finished Product Copper

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

An Introduction to the Chemistry of Metal Extraction

In concentrating copper ores, for example, pine oil is often used. The pine oil binds to the copper compounds, but not to the unwanted rocky material. The treated ore is then put in a large bath of water containing a foaming agent (a soap or detergent of some kind), and air is blown through the mixture to make a lot of bubbles.
