Copper corrosion is a slow process, so its easy to preserve the sheen of a copper, brass, or bronze item. in fact, it takes decades for copper to develop a greenish top layer. in addition, all it takes to polish these metals is an overthecounter metal polish or homemade mix and a clean cloth. some copper alloys, however, tarnish fast, so.
Copper electrowinning circuit of a plant having lsxew configuration and using permanent cathode technology consists of a stainless steel cathode, an inert anode lead alloy, and the copper electrolyte that contains cu2, fe3, fe2, co2, and so42 as major elements.
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.
Copper is found alongside many other types of ore. it can be found near gold, silver, zinc, lead, and other types of metal deposits. when mixed in with other ores, copper is not usually found in great abundance. until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.

Copper refining explained stepbystep. in refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.
Electroplating is mainly done for avoiding corrosion of metals and for decorative purposes.electroplating is a widely used process in many industries like automobiles, airplanes, electronics, jewelry, toys and many more. electroplating is conducted in an electrolytic cell. the metal to be electroplated is connected to the cathode.
