Cacoxenite is an iron aluminium phosphate mineral [5] with formula: Fe 3+ 24 Al(PO 4) 17 O 6 (OH) 12 ·17(H 2 O). [4] Cacoxenite is associated with iron ores. [6] The name comes from the Greek κăκός for "bad" or "evil" and ξένος for "guest" because the phosphorus content of cacoxenite lessens the quality of iron smelted from ore containing it.
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
For example, amethyst is a variety of quartz with a purple tinge due in part to iron impurities. Mineral varieties can be further subdivided into sub-varieties. [1] Unlike mineral species, mineral varieties are not defined or named by the International Mineralogical Association (IMA).
