-
C.
alumina refinery
An alumina refinery is an industrial facility that processes bauxite ore through chemical and physical methods to produce alumina (aluminum oxide), the primary raw material for aluminum production.
-
D.
copper smelting industry
The copper smelting industry encompasses the facilities, processes, and technologies involved in extracting and refining copper from its ores into usable metal products.
-
E.
