Slag is a product of:

A

flux and coke

B

coke and metal oxide

C

flux and impurities

D

metal and flux

Text Solution

Verified by Experts

The correct Answer is:
C
In many extraction processes, an oxide is added deliberately to combine with other impurities and from a stable molten phase immiscible with molten metal called a slag. The principle of slag formation is essentially the following. Nonmetal oxide (acidic oxide) `+` Metal oxide (basic oxide) `rarr` Fusible (easily melted) slag.
