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 (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

copper oxide is then subjected to a reducing atmosphere to form purer copper. The fire-refined copper is then cast into anodes for even further purification by electrolytic refining. Electrolytic refining separates copper from impurities by electrolysis in a solution containing copper sulfate (Cu2SO4) and sulfuric acid (H2SO4). The copper anode ...

steadily. Cobalt is produced mostly as a by-product of other major metal extraction processes – mainly copper and nickel – and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo (DRC) copper-cobalt production is coming to the fore once again after a 20-year period of decline.

Hydrometallurgy & Metal recovery - Nickel/Cobalt purification

Cobalt is a brittle, hard transition metal with magnetic properties similar to iron. It is mainly used as an alloy with iron, nickel or other metals to produce corrosion and wear resistant products for high temperature applications (such as jet engines, gas turbines, etc.). Cobalt is normally produced as a by-product of nickel or copper mining.

His-tagged Proteins–Production and Purification | .Deze pagina vertalen

Copper ions bind his-tags more strongly than cobalt or nickel. This provides the highest possible binding capacity but also the poorest specificity. For this reason, copper IMAC is commonly used only for binding applications in which purification is not the objective (e.g., plate-coating of an already-purified His-tagged protein for use in an ...
