Question
Which of the following statement is correct
Options
A.Roasting is unnecessarily done for Fe-extraction because there is no sulphide ore
B.In the smelting step of Cu-extraction, reduction of the ore takes place
C.Ores may not be mineral
D.Sphalerite is the ore of the zinc
Solution
Ferrous is having sulphide ore.
A mineral is the native form in which the metal exists. Example magnetite is a mineral of Iron of the formula Fe3O4, which is extracted from the ore which is rich in it
.Sphalerite ((Zn,Fe)S) is a mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety, marmatite.
