Copper Processing
Copper is a unique versatile metal used by ancient civilizations for thousands of years for tools and decorative items. Today, due to its versatile properties, copper is one of the most widely used metals in the world. Copper is ductile, malleable and conducts electricity, making it an essential component for electrical wiring, motors and transformers. Copper has also been utilized for its excellent heat conductivity properties and has been widely used in various industries like plumbing, refrigeration and automotive.
The processing of copper begins at the mine site, where the copper ore is extracted from the ground. The ore is then transported to the processing facility, where it is crushed and the valuable minerals separated from the rest of the rock. The remaining material, called tailings, is discarded. Depending on the level of purification needed, concentration processes such as froth flotation or leaching are used to separate the valuable minerals from the tailings.
The refined ore is usually heated in a furnace to produce copper metal, which is then cast into shapes and heated once more to produce semi-finished products. Once the parts are manufactured, they are subjected to a variety of processes, including heat treatment, machining, and plating, to impart specific beneficial characteristics. Aluminum, nickel, and bronze alloys are commonly added during the processing of copper items to improve the metals strength and thermal properties.
Copper can also be electroplated. This process involves dipping the copper piece into a tank of copper sulfate solution and applying an electrical current. This causes copper ions to be transferred from the solution and onto the surface of the part. The part is then heated to ensure the plating adheres and then polished to give it the desired finish.
Copper processing is incredibly efficient and requires very little energy to produce a variety of useful items and components. Its high electrical and thermal conductivity allows it to be used in a variety of applications, from electrical wiring and connectors to refrigeration systems and plumbing. In addition, its malleability and ductility makes it easy to shape for purposes ranging from tools to decorative items. From its earliest use by ancient civilizations, to its current wide-spread use, copper remains a truly indispensable metal.
