What is gangue called?
In mining, gangue (/ɡæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.
What is the difference between ore and tailings?
is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which—at the time of the rock’s evaluation and proposal for extraction—are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials’ present-day economic values …
What is the difference between ore and gangue mineral?
Naturally occurring elements and compounds are called Minerals. Minerals with high percentage of metal, that can be extracted profitably is known as Ore. During extraction of ores some impurities like sand, soil are removed from ores. These impurities are called Gangue.
What are tailings used for?
Tailings ponds are used to store the waste made from separating minerals from rocks, or the slurry produced from tar sands mining. Tailings are sometimes mixed with other materials such as bentonite to form a thicker slurry that slows the release of impacted water to the environment.
What is coal gangue?
Coal gangue, a solid waste generated during coal mining and washing, accounts for approximately 10%–15% of the total coal production. The accumulative amount of coal gangue is largely increasing associated with coal mining activities, becoming one of the largest industrial residues.
What are the types of gangue?
The dominant gangue minerals in VMS ores are quartz, chlorite, muscovite, carbonates, and sulfates (mainly gypsum and barite). The same minerals form the dominant alteration in host rocks affected by the ore fluids (see below). Minor albite, epidote, amphibole, and tourmaline may also be present in the ores.
What is the difference between tailings and waste rock?
Waste rock is bedrock that has been mined and transported out of the pit but does not have metal concentrations of economic interest. Tailings are the finely ground residuals that remain after the mill process has removed the valuable metals from the ore.
What are slag and tailings?
As nouns the difference between slag and tailings is that slag is whipped cream or slag can be apoplexy while tailings is the waste that remains after the minerals have been extracted from an ore by ore dressing; gangue, slimes.
Is Quartz a gangue?
Quartz is by far the most common iron ore gangue mineral overall, whereas clays (kaolinite and gibbsite) predominate in weathered supergene altered and near-surface exposures of ore deposits, while minnesotaite and stilpnomelane are the most common silicate minerals in unweathered iron formation deposits.
What is the difference between gangue and waste?
As nouns the difference between waste and gangue is that waste is a waste land; an uninhabited desolate region; a wilderness or desert while gangue is {{context|mining|lang=en}} the earthy waste substances occurring in metallic ore.
What do tailings mean?
Definition of tailing 1 : residue separated in the preparation of various products (such as grain or ores) —usually used in plural. 2 : the part of a projecting stone or brick inserted in a wall.
Is pyrite a gangue?
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).
What are tailings in mining?
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
What is a gangue in mining?
In mining, gangue ( / ɡæŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.
What is the difference between ore and gangue?
The main difference between Ore and Gangue is that the Ore is a rock with valuable metals, minerals and elements and Gangue is a is the term used to describe rocks that cannot be used in the miners’ language.
What is the difference between overburden and tailings?
It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals.
