PROCESS The patented Intec Copper Process was developed for the production of copper at LME Grade A purity from sulphide concentrates. Essentially, the Intec Copper Process consists of the three sequential circuits of leaching, purification and electrowinning. A simple flow diagram for the Intec Copper Process is shown in Figure 1.
The most eligible process plan for each job is selected first to minimize the total processing time or production cost, and then jobs with determined process plans are scheduled [2] .

Though Copper conducts electricity with about 40 percent less resistance than aluminum, it is avoided in the semiconductor manufacturing process. Copper is considered as semiconductor killer. It rapidly diffuses into silicon and changes its' electrical properties that can prevent the transistors from functioning.

The smelting process involves heating and melting ore to extract metal. Refining refers to any process increasing the grade or purity of the metal. The result of the refining process for copper production is copper cathode, which is generally 99.9 percent pure. The figures below represent global production and trade of refined copper (ICSG, 2015).

The electrorefining process refines metals or compounds at a high purity for a low cost. The pure metal can coat an otherwise worthless object. Let's consider the electrorefining process of copper: At the anode, there is an impure piece of copper that has other metals such as Ag, Au, Pt, Sn, Bi, Sb, As, Fe, Ni, Co, and Zn.
