The veins in the area share similar characteristics with many of the more prolific deposits in the VCMD, including ore mineralogy, gangue type and alteration assemblages.Kaynak: marketwire.com

In mining, gangue (pronounced "gang") is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in

slickens are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue ) of an ore .

Skarn is an old Swedish mining term originally used to describe a type of silicate gangue , or waste rock, associated with iron-ore bearing

William Haynes in 1869 patented a process for separating sulfide and gangue minerals using oil and called it bulk-oil flotation.

In extractive metallurgy , beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product

Mineral processing often relies on the formation of froth to separate rich minerals from gangue . In the process chemicals are added and

from gangue by means of oils, fatty acids, or other substances which have a preferential affinity for such metalliferous matter over gangue."

concentrations of copper , gold and uranium ore s hosted within iron oxide dominant gangue assemblages which share a common genetic origin.

As most ores are impure, it is often necessary to use flux , such as limestone , to remove the accompanying rock gangue as slag .

minerals such as quartz, mica and feldspar, collectively known an "gangue It was relatively easy to separate these minerals on the basis

The worthless gangue was then disposed of, often by draining. Usually a set of buddle pits was utilised, with the richer central deposits in

The heavier ore is tossed up through the water and appears as a crescent shaped patch at the top of the charge with the lighter gangue

The packing (gangue material used for filling) from the upper main gangways was placed in the exhausted cavities (the so-called 'old man'

Quartz occurs in hydrothermal veins as gangue along with ore minerals. Large crystals of quartz are found in pegmatite s.

The sulfate minerals occur commonly in primary evaporite depositional environment s, as gangue minerals in hydrothermal veins and as

remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value.

or by acid leaching (dissolving) the gangue with hydrofluoric acid (for a silicate gangue) or hydrochloric acid (for a carbonate gangue).

For example they are found within cementing minerals of sedimentary rocks , in gangue minerals such as quartz or calcite in
