What is the difference between ore mineral and gangue minerals?

The part of an ore that is not economically desirable and that can not be avoided in mining is known as gangue. The valuable ore minerals are separated from the gangue minerals by froth flotation, gravity concentration, and other operations known collectively as mineral processing or ore dressing.

What is an ore What is the meaning of 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.

Does ore contain gangue?

Ore, as mined, contains ore minerals, gangue minerals, and country rock.

Which is the gangue in iron ore?

From Miyano (1987). From Klein and Bricker (1977). Magnetite (Fe3O4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin….2.2. 1 Common iron ore and gangue minerals.

	Chemical formula	Description
Pyrite	FeS2	Iron sulfide
Pyrolusite	MnO2	Manganese dioxide
Siderite	FeCO3	Fe-carbonate

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 waste rock called?

Definition. The primary and most prevalent waste generated by many mining operations is waste rock, or overburden.

What is the difference between metal and ore?

Ore- A mineral occurring in sufficient quantity and containing enough metal to permit its recovery and extraction at a profit. Metal- An alloy of two or more metallic elements. Therefore, Rocks have minerals, which in large concentration are called ores and these are mined for metals!

Are tailings and gangue the same thing?

As nouns the difference between gangue and tailings is that gangue is (mining) the earthy waste substances occurring in metallic ore while tailings is the waste that remains after the minerals have been extracted from an ore by ore dressing; gangue, slimes.

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).
