The composition of the sulfide minerals can be expressed with the general chemical formula A m S n, in which A is a metal, S is sulfur, and m and n are integers, giving A 2 S, AS, A 3 S 4 and AS 2 stoichiometries. The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures.

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 ...

12.3 Primary Copper Smelting

iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in …

Types of Ore | MiningHallOfFame.org

The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals with varying percentages of copper in the chemical formulas of those minerals. The richest grade of copper ore is native copper, which is pure copper (). Many metallic ores occur as sulfide minerals.
