Sulfide ores [ edit] Secondary sulfides—those formed by supergene secondary enrichment—are resistant ( refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.

How do you neutralize silver oxide? Silver Oxide can be removed very easily at home. All you need is some foil, boiling water in a dish, salt and your tarnished jewelry. When combined together, the salt and boiling water help remove the silver oxide from silver products and the foil helps gives back the shine.
