In mineral deposit …of valueless minerals, collectively called gangue. The more concentrated an ore mineral, the more valuable the mineral deposit. For every mineral deposit there is a set of conditions, such as the level of concentration and the size of the deposit, that must be reached if the deposit is to be… Read More
Key gangue minerals include quartz, iron carbonates (siderite and ankerite), and iron silicates (minnesotaite, greenalite, stilpnomelane, and cummingtonite) (Table 2.5).
Johns Hopkins University (JHU) will develop sustainable mining of critical elements from gangue minerals. The concept is based on the electrosynthesis of hydrochloric acid or HCl and base (sodium hydroxide or NaOH) via salt splitting and using renewable electricity as …
This chapter discusses the methodology for characterisation and identification of the minerals defined and selected in Chap. 133 as common gangue minerals.
In mining, gangue (/ ɡ æ ŋ /) [1] 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 ...

In mining, gangue (/ ɡæŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.
This chapter addresses the concept of gangue minerals, as an unavoidable company of ores, and comprises some introductory remarks to address the difficult problem of gangue characterisation by reflected light, RL, microscopy.
Gangue minerals are the unwanted materials that are extracted along with ore during mining. They typically consist of various types of rock and minerals that do not contain any valuable metals and must be separated from the desired metal-rich ore.
Gangue is from the Greek, gang, meaning "vein of metal," the form gangue being of French derivation. As generally used, gangue minerals have no commercial importance in a particular period of time, possibly becoming ore minerals at a later date. They are commonly silicates, carbonates, or fluorides, more rarely sulfides.
