Ores Of Copper

Many minerals are actually copper ores, meaning they contain copper that could actually be extracted. Copper weathering is often involved in the unique coloration of specimens. Popular minerals that fall in this category include azurite, malachite and chrysocolla.

Copper Ore An Overview Sciencedirect Topics

The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching. An acid solution is often mixed with the ore during agglomeration to initial leaching while the material is being stacked.

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use. The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

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 in an ore can vary from 0.4 percent to more than 12 percent.

Oxide Copper Smelting Process. Smelting oxidized copper ores to black copper, as the metal thus recovered is called, is one of the simplest of all smelting operations. The ore with flux and coke is charged into a suitable cold blast furnace the metal is collected in the crucible until enough is present to tap out into the ingot molds.
