Definition of primary ore mineral

Definition of primary ore mineral. An ore mineral that was deposited during the original period or periods of metallization. The term has also been used to designate the earliest of a sequence of ore minerals, as contrasted with later minerals of the same sequence, which some writers have called secondary. To avoid confusion, Ransome proposed

Ore minerals

Uranium The chief primary ore minerals are uraninite, pitchblende (a mixture of various oxides), coffinite and a host of secondary minerals such as carnotite and autunite. Vanadium Recovered from petroleum residues also produced from vanadium bearing magnetite rocks. In the past it was recovered from minerals in uranium deposits. Zinc The primary zinc ore mineral is sphalerite, zinc

Primary mineral

A primary mineral is any mineral formed during the original crystallization of the host igneous primary rock and includes the essential mineral(s) used to classify the rock along with any accessory minerals. In ore deposit geology, hypogene processes occur deep below the earth's surface, and tend to form deposits of primary minerals, as opposed to supergeneprocesses that occur at or near the surface, and tend to form

Ore Mineral an overview ScienceDirect Topics

Primary ore minerals fill open space in intensely altered vuggy silica where primary rock minerals were fully leached away before precipitation of the ore minerals. The common ore minerals are enargite/luzonite, covellite, pyrite, gold-rich electrum, and native gold. Description of electrum and gold textures in relation to enargite/luzonite, covellite, and pyrite is rare, apparently owing to

Hematite: A primary ore of iron and a pigment mineral

Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.

ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G

PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore. Identified associations have been widely and successfully used

The colors of ore minerals, which range from pure white to gray, are one of their most characteristic and useful properties. As color is a function of the character of the human eye, each observer must make his or her own descriptions of the colors of minerals and must not be disconcerted if the pale cream mineral they have just observed is described as light yellow by someone else, for

Prospecting for Minerals 911 Metallurgist

11/01/2017 Oxidation of primary ore minerals near the surface may result in the solution and removal of the ore-forming minerals from their original position. Where conditions are favorable these materials are carried downward and redeposited, thus enriching lower parts of the mineral deposit. In areas where the rainfall is great enough, however, the minerals may be dissolved and completely removed

Lead ore and mines Minerals and mines Foundations of

Primary lead veins. The primary lead ore was found in thin veins cutting through the rock. In these veins, the galena occurs as either thin layers encrusting on the walls of the vein, or as thin bands, pockets or crystals within the vein. The veins were always associated with other waste minerals known as ‘gangue’, usually calcite (CaCO 3) or barytes (BaSO 4). Many of these veins were very
