Electrorefining of Copper

Electrorefining of Copper

Firerefined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage

Copper Refining: From Ore to Market | INN

The copper is concentrated further by slurrying the ground ore with water and chemical reagents. In this process, air is blown through the mixture, and the copper floats to the top. The copper is then removed with a skimmer. At the end of this step, copper concentrations are typically between 24 and 40 percent.

How and When to Perform a Copper Sulfate Test — Omnia MFG

The copper sulfate test is a visual method of determining the existence of free iron in specifically stainless steel. In many cases, the copper sulfate test is used as a pass/fail examination of a passivation process on a part or stock material, but it can also be used as a test to determine if passivation is necessary in the first place.

Averatek I Technology

This type of process often requires that a thin tie coat of chromium, nickel, or tungsten be vacuum deposited on the substrate before the copper is vacuum deposited. These processes have provided a nonadhesive approach to achieve thin metal, but the additional expense of the vacuum sputtered processes and the compatibility issues of the tie coat layer create limitations for applications.
