Indium (In #49) is the next element on the periodic table for my APEX mineral collection.
Indium Minerals - There are no practical Indium minerals. Indium only exists as a minor contaminant in other minerals.
Indium is a common impurity in Zinc ores, and it is most often isolated during the production of Zinc. Indium emits a high-pitched "cry" when bent and is able to "wet" glass.
