Question

'In the process of reduction of concentrated ore to zinc spelter, ZnO is made into briquettes.' Give reasons.

Answer 1

Generally, briquetting is a process for compressing
fine materials into small blocks, or agglomerates, of
sufficient mechanical strength to resist reasonable
handling and weathering without deterioration. The
main purpose of briquetting in the zinc oxide industry
is to form strong briquettes composed of a
homogenous mixture of the impure zinc oxide and the
petroleum coke which will not impede the flow of
gases or seriously disintegrate during the reducing
operation
