The definition of gangue is worthless rock or mineral in which valuable minerals are found. An example of gangue is the rock surrounding a deposit of gold. ... The commercially worthless mineral matter associated with economically valuable metallic minerals in a deposit.

What is called gangue?

In mining, gangue (/ɡæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. ... It is a necessary, and often significant, aspect of mining.

What is gangue short answer?

A gangue in chemistry can be defined as an unwanted material or impurities in the form of sand, rock or any other material that surrounds the mineral in an ore deposit. This substance is common when it comes to the aspect of mining.

What are the types of gangue?

The dominant gangue minerals in VMS ores are quartz, chlorite, muscovite, carbonates, and sulfates (mainly gypsum and barite).

What is an ore Class 10?

Metals found in a combined state in the earth's crust are known as minerals. Only those minerals that have a relatively high concentration of metal and can be extracted in an easy and cost-effective process are called ores. ... The relative abundance of metals varies in the earth's crust.

What is slag give example?

Slag is waste matter separated from metal during smelting. An example of slag is the iron and silica that is removed during copper and lead smelting. ... An example of to slag is for the heat of copper smelting to remove the iron and silica from the copper.

What is Auto reduction give example?

Thus, in simple words we can say the auto reduction process is used in the preparation of less electropositive metals like Cu, Hg, Pb etc. Some of the examples are as following, Copper (Cu) ore extraction: Here, partial roasting of sulphide ore of Cu to give the oxide.

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 is froth flotation 12?

Principle: The principle of froth floatation is that sulphide ores are preferentially wetted by pine oil, whereas the gangue particles are wetted by water. Collectors are added to enhance the non-wettability of the mineral particles. ... Example: For an ore containing ZnS and PbS, the depressant used is NaCN.

What is metallurgy class 10th?

Metallurgy is defined as a process that is used for the extraction of metals in their pure form.

What is flux class 10th?

Flux is a substance added to the ore to remove the gangue from it by reacting with ore. If the impurity is acidic substance, basic substance is used as flux and vice-versa.

What is gangue and slag?

Gangue means the impurities present in the ore. The next term is flux. During the process of removing the impurities present in the ore some of the impurities or the gangue cannot be easily removed. ... The substances which are formed when gangue and flux combine are known as slag.

What is gangue and ore?

1) mineral -the naturally occuring compounds of elements are known as mineral. 2) ore- the mineral from which an element can be extracted easily and profitably is called an ore. 3) gangue- the impurities present in ore such as sand rock etc is known as gangue.

What is slag in chemistry class 12?

Slag is fusible mass, which usually floats over molten metal, obtained by the reaction of the flux with impurities present in the concentrated ore.

What is meant by Autoreduction?

Autoreduction (from the French term autoréduction) is an anti-capitalist and collective practice by a group of people to impose a lower price for a product or service until it is free.

What is smelting Class 12?

Smelting is a process of applying heat to ore to extract a base metal. it's a sort of extractive metallurgy. ... Smelting uses heat and a chemical reducer to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducer is usually a fuel source of carbon, like coke.

What is reduction with Aluminium?

Some metal oxides cannot be reduced satisfactorily by carbon. For them, aluminium, a more reactive metal, is used. The process is called thermic process or alumino-thermic process.

What is slag in chemistry class 10?

Slag: When the molten metal in stirred with logs of green wood impurities get oxidised. These oxidised impurities formed over the surface of the molten metal is called slag.

What is pig iron?

Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces.

What is slag formula?

The lead oxides are reduced by carbon forming CO and CO₂ gases. To form slag, soda ash (Na₂CO₂) is added. The slag can generally be expressed by the formula FeSNa₂S(O).

What are veins and lodes?

A vein is a distinguished sheetlike body of crystallized metals inside a rock. ... A Lode is a sediment of metalliferous ore which is enclosed in a gap or also known as the crack in a rock composition. It is also known to be formed from vein of ore which is inserted or deposited between beds of rock.
