Question

(a) Baryte, (b) Galena, (c) Zinc blende and (d) Copper pyrites. How many of these minerals are sulphide based?

Answer 1

Earth’s crust contains some naturally occurring components called minerals in which metal compounds are found. Ores can be said to be those minerals from which metal can be economically and easily extracted.

$\begin{array}{cc}\text{Baryte}& BaS{O}_4\\ \text{Galena}& PbS\\ \text{Zinc blende}& ZnS\\ \text{Copper pyrites}& CuFe{S}_2\end{array}$

Of the given minerals, only $3$ are sulphide based.
