Question
Slag is a product of :
Options
A.flux and coke.
B.coke and metal oxide.
C.flux and impurities
D.metal and flux.
Solution
In many extraction processes, an oxide is added deliberately to combine with other impurities and form 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) → Fusible (easily melted) slag.
Nonmetal oxide (acidic oxide) + Metal oxide (basic oxide) → Fusible (easily melted) slag.
