Cacoxenite is an ironaluminium phosphate mineral with formula: Fe24Al(PO4)17O6(OH)12·17(H2O).It is associated with iron ores. The name comes from the Greek κăκός for"bad" or "evil" and ξένος for "guest" because thephosphorus content of cacoxenite lessens the quality of iron smelted from orecontaining it.
It was first described in 1825 for an occurrence in the Hrbek Mine, Bohemia,Czech Republic. It occurs as a secondary phase in oxidized magnetite and limonite deposits. It also occurs in novaculites and in iron and phosphorus rich sediments.
