Safflorite occurs in hydrothermal veins of moderate temperature and pressure
(Webmin, HOM), associated with
silver, bismuth and
At the Langis mine, Cobalt, Ontario, Canada, safflorite pseudomorphs after silver have been found (KL p134).
There is a complete solid solution between safflorite and löllingite, limited solution of cobalt in rammelsbergite and no solid solution between löllingite and rammelsbergite (AM53.1856, Mindat).
