A
smelter
B
gangue
C
mineral resource
D
petroleum
Explanation: 

Detailed explanation-1: -When extracting the seams, there is additional waste rock that must be separated from the ore. This additional waste rock is called gangue. When the gangue is processed (finely ground) more waste material is produced which is called mine tailings.

Detailed explanation-2: -Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them. The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt.

Detailed explanation-3: -Explanation: Slag: Slag is a product of Flux and impurity. Slag is a waste matter separated from metal during smelting and other metallurgical and combustion processes from impurities in the metals.

Detailed explanation-4: -The mining waste consists primarily of gangue, which is the rock that must be removed in order to access the ore and tailings that remain after the ore has been crushed, ground and enriched into a mineral concentrate.

Detailed explanation-5: -Gangue is soil, sand, or rock waste.
