Description

Abstract" This is a review, with annotated bibliography, of the mode of occurrence of the element indium. It is not a list of specific ore deposits, but a summary of the types of minerals and rocks in which indium has been reported to occur. In addition, the unpublished spectrographic studies of the Geological Survey on mill and smelter products are summarized, best sources of indium are indicated, and suggestions are made for further investigations. Indium has been found to occur most abundantly in sphalerites. The amount ranges from traces to maximum of 1.0 percent. Dark sphalerites are reported richer in … continued below

In addition, the unpublished spectrographic studies of the Geological Survey on mill and smelter products are summarized, best sources of indium are indicated, and suggestions are made for further investigations. Indium has been found to occur most abundantly in sphalerites. The amount ranges from traces to maximum of 1.0 percent. Dark sphalerites are reported richer in indium than light-colored sphalerites. Up to 0.1 percent indium has been reported in chalcopyrite and bornite, but these minerals generally contain very little indium. There is an unverified report of a pegmatite in Utah containing 1.0 to 2.8 percent indium. Some residues in zinc smelting contain more than 1.0 percent indium and are the present source on indium. No better source can be suggested but steps should be taken to ascertain that this source is being fully exploited. Tin sulfide smelter products should be checked. An effort should be made to check the Utah pegmatite occurrence.
