Renierite is a rare copper zinc germanium bearing sulfide mineral with the chemical formula (Cu,Zn)11(Ge,As)2Fe4S16. It occurs at the Kipushi Mine, Democratic Republic of the Congo; and Namibia, among other places.
Renierite was named after Armand Renier (26 June 1876 – 9 October 1951), a Belgian geologist and director of the Belgian Geological Survey.[2][3]
