Indium distribution in sphalerite from sulfideoxide Four distinct types of sphalerite are identified which differ with respect to ore texture and the concentration of In 0744572 ppm Subordinate amounts of In also occur within chalcopyrite and within andradite garnet an abundant mineral in the skarn at Dulong and possibly accounting for a significant proportion of total In
Although indium is commonly enriched in sphalerite the sphalerite grains in the concentrates are too small to recognize a whole series of thin growth zones reflecting the oscillatory zonation of indium which occurs within single sphalerite grains Ohta 1989 Shimizu and Morishita 2012 . 3.1.2. Ashio deposit
Sphalerite can be found in many ore veins of sulfide minerals commonly associated with galena and pyrite. Miners call sphalerite "jack" "blackjack" or "zinc blende." Its impurities of gallium indium and cadmium make sphalerite a major ore of those metals. Sphalerite has some interesting properties.
Indium minerals recognized are; unnamed Zn-In mineral hereafter abbreviated as ZI whose composition is at the midst of sphalerite and roquesite unnamed Ag-In mineral AI of AglnS 2 composition ...
Instead indium is usually a trace constituent of more common ore minerals such as sphalerite and chalcopyrite. 45 46 From these it can be extracted as a by-product during smelting. 47 While the enrichment of indium in these deposits is high relative to its crustal abundance it is insufficient at current prices to support extraction of indium as the main product.

Because of the interference between indium and tin Indium is present in both types of sphalerite but in the analysis of tin-rich minerals by EPMA Schwartz- whereas the red crystals of sphalerite contain between Schampera and Herzig 2002 a systematic increase of 3 and 7 wt% In the yellow type has 0.7 to 2 wt% In 0.05 to 0.1 wt% In2O3 was registered during analysis Table 1 .
The sphalerite from the Burgstaetter Gangzug a vein system of the Upper Harz Mountain nearby the town of Clausthal-Zellerfeld exhibits a very interesting and partly complementary incorporation pattern of Cu In and Sb which has not yet been reported for natural sphalerite. A sphalerite specimen was characterized with electron probe micro-analysis EPMA and atom probe tomography APT ...
Four distinct types of sphalerite are identified which differ with respect to ore texture and the concentration of In 0.74-4572 ppm . Subordinate amounts of In also occur within chalcopyrite and within andradite garnet an abundant mineral in the skarn at Dulong and possibly accounting for a significant proportion of total In.
