Ore | National Geographic Society

Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. It is a common material in pipes and plumbing material.

The Ancient History of Copper - ThoughtCo

Researchers now believe that copper came of regular use for a period—referred to as the Copper Age—prior to its substitution by bronze. The substitution of copper for bronze occurred between 3500 to 2500 BCE in West Asia and Europe, ushering in the Bronze Age . Pure copper suffers from its softness, making it ineffective as a weapon and tool.

Gold and copper often occur together in ores, an occurrence which creates processing difficulties since cyanide leach solutions are not selective for gold. Copper contamination can result in serious problems throughout the conventional carbon-inpulp process, often making the operation uneconomic. This thesis describes electrochemical studies of two ways of dealing with copper contamination.

copper ore and gold extraction

The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
