Copper Ore Types: Sulfides vs. Oxides | Investing News NetworkApr 20, 2017 . For instance, hydrometallurgical processes are used to treat copper oxide ores that are dominated by soluble minerals, such as copper carbonate minerals. These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate.important sulphite minerals of copper,List Sulphide Minerals - 911 MetallurgistTaking the atomic weight of copper as 64, there are 64 parts of copper, 56 parts of iron, and 2 x 32 = 64 parts of sulphur, a total of 184 parts; hence, the proportion of copper is 64/184 = .348 = 34.8%, which is also .

Sulfide mineral | Britannica

The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures. Almost all sulfide minerals have structural arrangements that belong to six basic types, four of which are important. These arrangements are close-packing combinations.

The Mineral Gallery - Sulfides Class - Amethyst Galleries

The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities,.

the genesis of a number of these pyrrhotitic copper deposits. The deposits formed at moderate and shallow depths by ascending thermal solutions constitute a very important group, which includes numerous deposits of ores of copper, gold, silver, lead, and zinc. Many of these deposits show important sulphide enrichment.

Molybdenum | Linus Pauling Institute | Oregon State University

Their rumen is the site of high sulfide generation, and the interaction of molybdenum with sulfur results in the formation of thiomolybdates. Tetrathiomolybdate, a thiomolybdate with four sulfur atoms, can form complexes with copper preventing its absorption and blocking the activity of copper-dependent enzymes.
