The recovery of indium from mining wastes
MetadataShow full item record
Scarcity and high demand has placed an economic pressure on the supply of indium worldwide; therefore, there is a global interest in increasing the recycling capacity for indium. This project’s main goal is the identification of secondary raw material resources for indium production; investigations were conducted on three zinc processing wastes namely a “tailings” sample which is a waste from flotation plant, a “jarosite” sample which is a waste from a hydrometallurgical plant, and a “ferrite” sample which is a waste from pyro-hydrometallurgical plant. Characterization work conducted showed ...
