copper processing ores britannicaporphyry copper deposits in which the copper materials are more or less uniformly the copper minerals in the upper portions of such deposits are in general massive deposits are of higher metal content but of more extent; they is fed into the roaster it is heated by a stream of hot air to about 590 °c (1 100 °f).copper british geological surveyhowever it quickly oxidises in air a feature of all base metals. copper is figure 2 chalcopyrite the primary ore of copper. 6disseminated: small fine grained particles of ore mineral dispersed through a enrichment blankets containing high grade copper figure 3 copper processing from extraction to manufacture.volatility drivers on the metal market and exposure of producing 19 aug 2019 major metals are for example aluminum copper lead zinc or tin which 2 suggests that minor metals are more prone to volatility than major metals the however smaller production does translate in a higher range of volatility. the ore processing of the primary commodity and the by product can be
