Mineral concentrators are becoming increasingly aware of the importance of the quality of the water that they feed into their milling and flotation circuits. It is speculated that different inorganic constituents of process water may yield different flotation results owing to the electrolyte–reagent–mineral interactions occurring in the pulp phase. These interactions …
Gangue dibedakan dengan lahan penutup (overburden) yang merupakan batuan buangan atau material-material lainnya yang menutupi bijih atau tubuh mineral yang dipindahkan selama penambangan tanpa diproses terlebih dahulu.

The rougher spiral concentrate is composed of all sizes of heavy minerals present in the feed, but the gangue content is generally finer than 28 mesh. Consequently, treatment of the rougher concentrate in the simple elutriation or single-pocket sizer produces an underflow of very high grade heavy mineral that is finished coarse concentrate.

The pulp rheology is an important factor affecting flotation performance. Gangue minerals have a significant impact on the rheological property of smithsonite (ZnCO3). The complex pulp rheology (high viscosity, poor dispersion) will adversely affect the grade and recovery of concentrate. To address this problem, the effect of gangue …

Quick Reference. That portion of an ore deposit which is of no commercial value but which cannot be avoided during mining; it is removed during processing as waste. Common …
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 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 …

2. Its fast to medium floating metal/mineral fraction that may or may not be overwhelmed by fast floating gangue and 3. Its slow floating metal/mineral fraction that competes with slow floating gangue. The scope of this note addresses points 1 and 2 above. Fast floating metal/mineral fraction (IMF) is nearly always recovered – that is, excluding
