demonstrates the softening process of annealing. Copper wire or tubing is quite soft in its initial state, allowing for a variety of uses where the tubing needs to be bent to a desired shape. Upon bending, the copper hardens due to work hardening (also called strain hardening). Enough bending will make it impossible to return it to its original ...

Copper mines are only set up where there is more than 5kg of copper per tonne of rock (% by mass). Ideally, the figure should be closer to 2%. The flow chart shows you how copper is extracted from its ore and converted into pure metal.

The annealing process is a fairly simple, yet vastly important part of making copper (or any other sort) of wire. In the drawing process the copper was cold worked, meaning no heat was applied to it. Because of all the stress and strain, the copper is fairly brittle after the drawing process, not flexible as copper .

The first stage of the production process is fire refining and anode casting process. Raw material of this process is blister copper, copper ingots and scrap copper. Fire refining takes place in THOMAS type furnaces at about 1250 o C. Refined molten copper which has % copper purity is poured into anode molds with a tolerance of ± 1 kg by using PLC controlled automatic casting system.

process improvements. Figure 1. Controlling Input to Electroplating Processes . PLATING BATH SOLUTIONS Initially, the electroplating sink used for depositing copper and tin was configured such that a tin plating tank was beside copper plating tanks (Figure 2). In this way, a direct coppertin electroplate process could be carried out.

Mar 19, 2011· The copper electrodes are immersed in a solution of sulfuric acid and copper(II) sulfate. Oxidation occurs at the anode, therefore copper metal is converted to copper (II) ions with the release of two electrons. At the cathode the opposite reaction occurs: copper (II) ions are joined with two electrons to form copper metal.

The most common applications for this process are steel, aluminum, and copper. When these metals are cold worked, permanent defects change their crystalline makeup. These defects reduce the ability of crystals to move within the metal structure and the metal becomes more resistant to further deformation.
