    Sep 24, 2018 The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely

    The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final
