    Ore vs Mineral . Mineralogy is the study of minerals. More than 4000 minerals have been discovered, and they have a crystalline structure. Inside the earth, due to heat and various other reactions, minerals and rocks melt together. When they are cooled slowly, crystals form. When this cooling happens over thousands of years, larger crystals may form. These are combined with various types of ...

  • Ore Mineral - an overview ScienceDirect Topics

    The metallic ore minerals are commonly metal compounds such as sulphides and oxides in which the metal content is high compared with rock-forming minerals. Natural concentrations of ore minerals form discrete ore bodies that may typically contain only a few percent of the valuable metal. Unlike many industrial minerals that find direct use after mining and limited beneficiation, the ore ...

    Mineral - Mineral - Occurrence and formation: Minerals form in all geologic environments and thus under a wide range of chemical and physical conditions, such as varying temperature and pressure. The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process ...

  • How Gold Ore is Formed ‎Genesis - 911metallurgist

    The origin of mineral veins, including those in which gold is contained, has long been discussed by geologists. The old theory that the quartz of veins was originally in a molten condition and was ejected from below into fissures is no longer maintained, although in 1860 H. Rosales brought forward evidence in its favour as far as the Victorian lodes are concerned. One of the theories now ...
