The indium content of zinc deposits from which it is recovered ranges from less than 1 part per million to 100 parts per million. Although the geochemical properties of indium are such that it occurs in trace amounts in other base-metal sulfides—

This review examines the current state of knowledge of indium cycling from ore to mine waste deposits and identifies opportunities for its recovery. The highest …

For the lack of key technologies for processing into indium tin oxide (ITO), more than 98% of the high quality ITO targets depend on imports. As the indium industry has been affected by policy, great changes have occurred in China's indium import/export trade, which has mainly focused on a few countries. ...

The indium (In)-bearing raw ore samples were obtained from a Canadian sulphide deposit. Fig. S1 ( Supplementary Material s) displays the technological process of the sample preparation for the flotation experiments, chemical analysis and process mineralogy research.

The processing of zinc ore using hydrometallurgical methods leads to the formation and accumulation of a by-product called jarosite, which contains concentrated precious metals. In this study, we propose the recovery of In and its separation from Cu, Zn, Fe, Pb, and Ag. This study also presents a proposal for a new technological procedure …
