Copper Ore - an overview ScienceDirect Topics

The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ∼50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Unlike the system for lead, the copper and Cu 2 S melts are nearly immiscible ...

Copper processing - Ores Britannica

Copper processing - Copper processing - Ores: 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.

How is Copper Made? The History of Copper Products

Sep 26, 2016  As mentioned, pure copper is rare because most of it is naturally combined with other chemicals to form copper ores. The most common copper ores—there are about 15 of them mined in 40 countries— are sulfide ores, where the copper has bonded chemically with sulfur. Sometimes copper ores contain gold, silver or nickel, although in minute ...
