Question

1During the extraction of copper, impurities float in the form of slag over the molten mixture of copper compounds. The slag obtained in this extraction is
A. Fes
B. Feo
C. FeSiO3
D. CuFeS2​

Answer 1

Answer:

The Process

The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicateslag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas

Answer 2

Answer:

The copper(II) ions in the chalcopyrite are reduced to copper(l) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicateslag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas
