Elecrolysis In Simple Electric Cells - Mini Chemistry ...
Example Of A Simple Electric Cell. Since zinc is more reactive than copper, oxidation will occur at the zinc electrode. Zinc will become the anode. Each zinc atom loses two electrons and is oxidised to a zinc ion. Zinc dissolves into the acid solution. Anode reaction: Zn(s) → Zn2+(aq)+2e− Zn ( s) → Zn 2 + ( aq) + 2 e −.

Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.

Copper rich alloys with cobalt have attracted attention largely due to their precipitation hardening behaviour. The alloy of composition Cu-2 wt.% Co when homogenized and aged at 600°C produces precipitates of nearly pure cobalt (90% cobalt and 10% copper). This can be seen from the equilibrium phase diagram shown in Figure 1.
