Dec 11, 2019· Gangue In mining, gangue () is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. 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.

These sulfide ores are separated from gangue (waste) material, then from each other, by froth flotation. Copper /Molybdenum Flotation Circuit Steps Grinding . Grinding mills liberate the ore from the gangue material (nonores silica, organics), and reduce it to an optimal size

(A) The concentration of ore involves physical and chemical methods. Froth floatation method is the physical method for the separating mineral from the gangue. (B) It is based on the difference in wettability of different minerals. The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water.

The usual objective of reducing the size of runof mine ore pieces is to separate the mineral of interest contained in the ore body from associated gangue minerals. As crushing only does not generally liberate a mineral, further size reduction is usually required.

Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate

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.

During the mining process, the materials that are extracted are grouped into two categories economic fraction, which is the desirable material that has a value, and uneconomic fraction, which is the gangue. Gangue must be separated out after the extraction process. The removal of the gangue from the ore is called ore dressing, or concentration of the ore.

Answer (1 of 3) Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore . e.g. pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commercially; likewise, quartz/calcite will b...

Feb 05, 2021· In the flotation process, the ground ore/gangue powder is mixed with a liquid reagent and inflated. Lower density ores rise in the foam and are collected, while useless gangue sinks and is discarded. In this way, flotation separates the metallic minerals from the useless gangue or molybdenite from copper sulfide in the case of copper

For example, the nonvaluable mineral components comprising gangue from a limestone containing ore are impurities such as chert, ironbearing rock, granite, quartz, and various other silicates. The methods used to separate limestone from gangue present in limestone ore include handsorting or other optical sorting methods.
