Copper Ore Crushed Properties

Presentation of copper

· To do this, the ore is crushed. Then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being is electrolysis. 5. Properties Of Copper Corrosion resistant Copper is low in the reactivity series. This means that it doesn't tend to corrode.

Resistivity

For example, pure pyrite has a resistivity of about 3x105 Ohmm but mixing in minor amounts of copper can increase the resistivity six orders of magnitude to 10 Ohmm. Conductivity properties of some important minerals can be summarized as follows: Pyrrhotite (FeS) is consistently highly conductive mineral.

Ball mills grind the crushed ore for subsequent flotation to produce a copper concentrate grade of approximately 30%. At Nkana the cobalt floats with the copper and then has to be separated out by a differential float using lime to alter the pH and sodium cyanide; this is not an exact process and as a result some of the copper remains within the cobalt stream which is .

Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.
