12.3 Primary Copper Smelting

12.3 Primary Copper Smelting

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Iodometric titration of copper Titration and titrimetric

Copper (I) thiocyanate is slightly less soluble than iodide, which makes concentration of Cu + even lower, increasing the oxidation potential of the Cu 2+ /Cu + system. Solution should be free of other substances that can oxidize iodides to iodine (for example Fe 3+ or nitrates).

The increase in temperature produced an increase in the recovery of copper from solids into the bulk solution. The leaching of dolomitic copper ore was favoured at low pH values (1.8<pH<3) than high ones (pH >3). The increase in pulverisation time increased the recovery of copper by sulphuric acid.

In this manner through a series of steps the copper ore is concentrated to an eventual value of over 28% copper. Waste rock particles do not adhere to the bubbles and drop to the bottom of the tank. The waste material that comes out of the bottom of the tanks at the tail end of this process is called "tailings.".

Molybdenum removal from copper ore concentrate by sodium

Molybdenum removal from copper ore concentrate by sodium

The removal of molybdenum from a copper ore concentrate by sodium hypochlorite leaching was investigated. The results show that leaching time, liquid to solid ratio, leaching temperature, agitation speed, and sodium hypochlorite and sodium hydroxide concentrations all have a significant effect on the removal of molybdenum.

Ore sample B shown in Part 1 is an example of the pebble treatment by the pulse pre concentration technique, in which 27% by mass of the pebbles can be rejected with a grade of 0.07% copper. In comparison, the returned pebbles have a grade of 0.28% copper, representing 91.5% metal recovery (Section 4.2.2 in Part 1) in the electrical pulse pre concentration process.
