Types of minerals | Minerals and Mineral Resources

Minerals containing some metal are often labeled as ore minerals. The most common minerals in this group are various sulfides, oxides and native elements. Typical examples are pyrite, galena, sphalerite, magnetite, haematite, uraninite or native gold, silver and copper. Gems and precious stones. There is no solid definition of precious stone or gem.

mineralogy showed that the main copper sulphide was bornite (Table I). Other copper sulphides noted were chalcocite, chalcopyrite, digenite and possibly enargite. Pyrite was the main sulphide gangue mineral. The chief silicate gangue phases were pyroxene, quartz and Kfeldspar. Mica was a minor constituent. The ore was crushed in a laboratory scale

Sulfide Minerals an overview | ScienceDirect Topics

MineImpacted Environments. Many of the most important base metals (such as copper, lead, and zinc) used by humankind are sourced mostly from sulfide minerals. In addition, many precious metals including gold, silver, and PGMs (platinum group metals) are often found in association with sulfidic ores.

CHALCOCITE (Copper Sulfide)

CHALCOCITE (Copper Sulfide)

Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It is not however the primary ore of copper due to its scarcity.

Copper Sulfide Assignment Point

It describes a family of chemical compounds and minerals with the formula Cu x S y. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores. It can be classified into three groups, namely monosulfide, disulfide and mixed monosulfide. Copper sulfide occurs naturally in nature as a mineral called covellite.

How can I calculate the empirical formula of copper sulfide?

Jan 10, 2015· In order to determine the empirical formula for copper sulfide (or for any compound, for that matter) you need to have some information about either the mass of one reactant and the mass of the product, or about the percent composition of the copper sulfide. For the first case, let's assume you are doing a lab experiment in which you heat a mixture of copper and sulfur in order to produce a ...
