Gangue Mineral an overview ScienceDirect Topics

There are many other major to minor gangue minerals associated with iron ore deposits including many different silicates (including amphiboles and chlorites), carbonates (siderite and ankerite), sulfides (e.g., pyrite), and oxides (e.g., pyrolusite).

Ore, gangue, ore minerals, gangue minerals

2021-5-21  Ore, gangue, ore minerals, gangue minerals. In most cases, an ore does not consist entirely of a single ore mineral but it is mixed with other valuable minerals and with unwanted or valueless rocks and minerals. The part of an ore that is not economically desirable and that can not be avoided in mining is known as gangue.

Define the terms: (a) Mineral (b) Ore (c) Gangue

Thus, ''every ore is a mineral but every mineral is not an ore.'' Gangue or Matrix: The unwanted impurities of sand and rocky materials present in the ore are known as gangue or matrix. we get a concentrated ore by removing the gangue present in it.

(c)The impurities present in the ore such that sand,rocks etc are known as Gangue. Darmaidayxx and 3 more users found this answer helpful. heart outlined.

Ore, as mined, contains ore minerals, gangue minerals, and country rock. A mass of mineral matter is not considered ore unless one or more of its ore minerals can be recovered on a profitable basis. As originally used, ore minerals were metal bearing (see Metallic Minerals).More recently, nonmetallic minerals of commercial importance are considered ore minerals (see Mineral Industries).

12. Supergene Ore and Gangue Characteristics

2012-3-8  In the traditional view, supergene ore and gangue minerals are the products of reactions between hypogene sulfide minerals and descending, acidic meteoric waters; these processes take place at or near the ground surface in subaerial environments (Guilbert and Park, 1986). In VMS deposits, copper and other metals are mobilized from primary massive sulfide ore and reprecipitated at depth. This precipitation of Cu sulfides with high Cu/S ratios can produce an economically significant copper enrichment at the reactive redox boundary between massive sulfide protore and downward penetrating fluids. The supergene enrichment “blanket” is overlain by an intensely altered and leached Fe oxide-rich gossan (the remains of the original massive sulfide)

Define the following terms. (i) Mineral (ii) Ore (iii)

Gangue. In chemistry, a gangue is an unwanted substance or impurity that surrounds the mineral in an ore deposit, such as sand, rock, or some other material. When it comes to mining, this material is very popular. Mineral dressing, mineral processing, or ore dressing are terms used to describe the method of separating gangue from mineral.

2009-8-26  Typical gangue minerals are pyroxene, feldspar, quartz, chromite and talc. Of these, talc is a naturally hydrophobic mineral and although it is present in relatively small quantities, it has a disproportionate effect as it has a strong froth stabilizing effect, increasing the recovery of other gangue minerals by entrainment. Talc recovery is

Depressants are added to flotation circuits to reduce naturally floatable gangue (NFG) present in ores, but under certain conditions have been shown to affect sulphide mineral recovery, particularly guar reducing the recovery of pyrrhotite. Copper sulphate is added to increase sulphide mineral recovery, but may also activate gangue particularly in the presence of dithiophosphate.
