Covellite : Properties, Formation and Uses » Geology Science

3. Chalcocite (Cu2S): Chalcocite is another copper sulfide mineral that often occurs in the same deposits as covellite. It is more commonly associated with secondary enrichment zones where primary copper minerals have been altered and leached, leaving behind secondary copper sulfides like chalcocite and covellite. 4.
