HYDROMETALLURGY|MINERAL PROCESSING
QUESTIONS AND ANSWERS GRADED A+
What is metallurgy? - ANS-The science and engineering of the physical and
chemical behavior of metallic elements, their compounds, and alloys.
3 Steps of Metallurgy - ANS-Concentration, Isolation, Purification
Mineral - ANS-Naturally occurring inorganic substance with definite composition &
crystalline structure.
Ore - ANS-Rock containing enough metal for profitable extraction.
Flux - ANS-Chemical cleaning agent for purifying ores.
Slag - ANS-Waste separated from metals during extraction.
Gangue - ANS-Worthless material mixed with valuable mineral in ore.
Tailings - ANS-Residue left after valuable minerals are removed.
Native Ores - ANS-Metal present in elemental form.
Sulphide Ores - ANS-Metal present as sulfide compounds.
Oxidized Ores - ANS-Metal present as oxide, carbonate, sulfate, silicate, or
hydrated forms.
Complex Ores - ANS-Ores with more than one valuable mineral.
Mineral Processing - ANS-First step after mining to concentrate valuable minerals;
also called ore dressing, beneficiation, milling.
Size Reduction - ANS-Liberates valuable mineral grains from gangue.
Sizing - ANS-Separate particles by size via screening/classification.
Concentration - ANS-Collect valuable minerals in small bulk.
Dewatering - ANS-Remove moisture before smelting or shipment.
2 Fundamentals of Mining Processing - ANS-Liberation and Concentration
Liberation - ANS-the release of valuable minerals.
