Before being subjected to the first process, the ores are broken into pieces of the size of a nut, and so assorted that the lot to be smelted may contain about eight or ten parts of metallic copper in the hundred. Moreover, as there is much gangue or earthy matter associated with the ores, they are, if possible, so mixed that they may serve as fluxes to

The smelting of copper ore in a blast furnace is the process of reducing the copper from its ores by subjecting the ores to a fierce heat in a cupola. Coke is the fuel used, and the fierce heat is obtained by turning into the cupola a blast of air heated to about 800 degrees Fahrenheit.

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

2021-6-7  The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the

The entire sequence of events leading to the recovery of copper from its ores and its conversion into metal is characterized by the expenditure of vast amounts of energy and complexity of processing. It would obviously be very desirable to minimize the effort put into breaking up the gangues with which the ore exists and put that energy exclusively into the copper compounds which one wishes to recover or

The principal ores of copper with the approximate percentage of copper found in each is as follows: Cuprite, a copper oxide which contains 89 per cent of copper. This is the ore that is richest in copper, frequently shading to crystals of native copper. Chalcocite, a copper

Copper is among the few metals known to ancient civilizations. Copper, gold, silver, platinum, and meteoric iron are the only metals found in their native state. However ∼90% of copper comes from sulfide ores. Most copper ores contain 0.5% Cu or less, iron being the principal metallic impurity. The ores are ground to a fine powder and concentrated (normally by floatation) to 20–25% Cu.

2006-6-27  Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper.

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper
