HYDROMETALLURGY Questions and Answers
Graded A+
Extraction of metals from ores at ordinary temperatures by water based process -
ANS-Hydrometallurgy
It is a branch of extractive metallurgy that uses the aid of an aqueous solution for
the recovery of metals from ores, concentrates, and recycled or residual materials -
ANS-Hydrometallurgy
METAL/MINERAL RECOVERY It is the final extraction of metal from solution - ANS-
METAL/MINERAL RECOVERY
removal of dissolved materials from soil by water moving downwards - ANS-
LEACHING
map of stable electrochemical phases in aqueous system - ANS-Pourbaix diagram
These diagrams are essentially phase diagrams that map the conditions of potential
and pH (most typically in aqueous solutions) where different redox species are
stable. - ANS-Pourbaix diagram
It is an Leaching Methods where resources in a deep deposit are dissolved in a
liquid and siphoned out - ANS-Solution mining (in-situ recovery)
Agitation leaching - ANS-It is a leaching method where chemical process of the ore
is mixed or slurried is kept in contact for a certain period of time with fluid to be
extracted.
It is a method where heap leaching and in-situ leaching are combined. - ANS-Dump
Leaching
It is a solution that produces smaller volume to handle richer pregnant solution -
ANS-Enrichment
The solution containing the metal ions is passed through a lot of bed of resins
whereby the material is recovered into resins - ANS-Sorption
Functionalized resins are used to exchange cations or anions with the solution -
ANS-Ion exchange
A small volume of stripping solution(acid) is passed through there sin,
simultaneously recovering the sorbed metal ions. - ANS-Elution
