sulfide | Definition, Classes, Formulas, & Facts | Britannica

Sulfides of many important metallic elements are naturally occurring minerals. For example, pyrite, which is also called fool's gold owing to its brassy yellow colour, is a sulfide of iron with the formula FeS 2. Pyrite is a major source of iron and is one of the most abundant of the sulfur minerals.

Introduction to Mineral Processing

This material is referred to as pregnant leach solution. Oxide copper minerals are very soluble in the leach solution. Sulfide minerals are rendered soluble by certain bacteria that feed on the sulfide minerals and convert them to soluble sulfates and other soluble forms. This biological action tends to maintain the acidity of the leach solution.

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.

Rock and Mineral Resources | Geology

Copper is enriched by processes during crystallisation of the granite and forms as chalcopyrite—a sulfide mineral, which is carried up with the granite. Sometimes granites erupt to surface as volcanoes, and copper mineralisation forms during this phase when the granite and volcanic rocks cool via hydrothermal circulation.

Examples for "sulfide ore" and how to use it - Nyanglish

English examples for "sulfide ore" - Two of the above-mentioned mines were free milling and two produced sulfide ore. They are also used for roasting a wide variety of sulfide ores prior to metal extraction. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores".

Mineralogy of Sulfides - Elements

Pyrite is the dominant sulfide in porphyry copper deposits, though it is chalcopyrite that is the most important ore mineral, along with bornite and various binary copper sulfides. In the related porphyry molybdenum deposits, it is molybdenite that dominates. The sulfides in such deposits occur as veinlets or disseminated grains in host intrusions.

List Sulphide Minerals

The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance. Iron Pyrites or Pyrite

Flotation of Copper Sulfide Ores - PDF Free Download

Sulfide copper ores are considered easy to treat provided that the main copper mineral is chalcopyrite. In case the ore contains secondary copper minerals, such as chalcocite, bornite and covellite, depression of pyrite may be a problem because the pyrite can be activated by copper ions generated during the grinding operation.

Sulfide minerals - Wikipedia

The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts.

Copper Mineral | Uses and Properties

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.
