How to Extract Precious Metals From Sulfides   Sciencing

How to Extract Precious Metals From Sulfides Sciencing

Precious metals can be found in ore deposits along with sulfur, and are known as sulfides. Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated ...

Gold and arsenic in iron sulfides from sediment

Gold and arsenic in iron sulfides from sediment

Gold is present in arsenian pyrite that forms overgrowth rims on, and narrow veinlets in, goldfree pyrite and possibly other minerals, but only to a minor extent. Auriferous overgrowth rims that may exhibit compositional zoning, either simple or oscillatory, range from approximately 25 mu m in thickness to the limits of microscopic resolution.
