The metallurgical method for obtaining a metal from its ore by roasting the ore and then reducing the resulting metal oxide is called ________.
A)zone melting
B)pyrometallurgy
C)leaching
D)hydrometallurgy
E)flotation

Question

Quizplus · Accepted Answer

The metallurgical method described in the question involves roasting the ore, which involves heating it to a high temperature in the presence of air to convert any sulfide minerals in the ore to oxides. The resulting metal oxide can then be reduced to the pure metal through pyrometallurgy, which involves high-temperature processes such as smelting or electro-refining. Therefore, B is the correct answer. The other options are not relevant to the described method.
