Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs .
The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

Australia''s ores vary from strong hard types (lump ores) to loose powder (fine ores), and from purplish blues to reds. Goethite ores are usually softer, more porous and easier to crush than haematite. Variations in chemical composition and physical state of the ore influence its usefulness, economic value, and the required smelting technique.

The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a ing agent which produces a kind of bubble bath. This is a rare chance to see a mill and flotation building before the roof is built.

Sulphide Gold Ore Treatment by Leaching and Flotation Process Previous Next Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.
In assessing the economic benefit of the extra processing that needs to be done to improve recovery from refractory or partially refractory ores, it is always important to consider the incremental improvement in gold recovery versus standard grinding and cyanidation, and the incremental increase in costs to achieve this improvement.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed..

Heap leach mining works well for large volumes of low grade ores, as reduced metallurgical treatment (comminution) of the ore is required in order to extract an equivalent amount of minerals when compared to milling. The significantly reduced processing costs are offset by the reduced yield of usually approximately 6070%.
