bismuthinite and silver ores

Tellurium, New MexicoIt is composed principally of quartz and fluorite, the other minerals noted being bismuthinite, pyrite, and tellurium. Assays show that the ore carries gold, but no more than a trace of silver, noteworthy amounts of which are present in the ores of the Mogollon district.Ore and Skarn Mineralogy of the Yamato Mine, .Copper and silver contents of ores produced from this mine in 1952–1953 were 4.2–7.8% and 40–220 g/t, respectively; tungsten contents in the scheelite‐rich part were generally 5–10 wt.% WO 3, and rarely reached 15% at maximum (Ueno & Doi, 1956).
