The effect of particle size on HVP breakage behaviour is ore-dependent. For a copper–gold ore with finely disseminated metalliferous minerals in veins, the larger particle size produces the higher body breakage probability and the larger change in A×b values, but its effect on product fineness (t 10) is insignificant.

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper …

Table 2 presents the optimal ore pre-concentration results achieved during these experiments. There is a pronounced propensity for the copper minerals to preferentially concentrate into the finer size fractions in the product after HVP treatment. For Ore 1, the copper grade in the −4.0 mm size fraction is 0.70% compared . Discussion

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely …

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
