gangue minerals consuming

Gangue Wikipedia

Minerals that were once thought of as gangue, and were dumped, may later find a commercial use. When this happens, the old dumps are often reworked to extract the wanted mineral. For example, in copper mines in the 19th century the mineral arsenopyrite was dumped until arsenic became popular as an insecticide later in the century. In the 21st century, the use of gangue has been considered from an environmental point of view. For e

Gangue minerals SpringerLink

Ore, as mined, contains ore minerals, gangue minerals, and country rock. A mass of mineral matter is not considered ore unless one or more of its ore minerals can be recovered on a profitable basis. As originally used, ore minerals were metal bearing (see Metallic Minerals).More recently, nonmetallic minerals of commercial importance are considered ore minerals (see Mineral Industries).

OVERVIEW OF GANGUE MINERALOGY ISSUES IN OXIDE COPPER

Silicate and limonite gangue minerals consume sulphuric acid during initial reaction with acid. However, the reaction by-products can partially regenerate sulphuric acid in subsequent reactions with each other and/or fresh ore. Acid consuming and regeneration reactions within particular gangue mineral groups and reaction product groups include the following: Acid consumption: Limonite minerals

tion of gangue minerals can aid in the recovery of valuable metals (Lottering et al., 2008). As the gangue dissolves, so the proportion of the mineral of interest that is exposed to the leach liquor in-creases, resulting in improved recoveries. The gangue–reagent interactions that occur during the acid leaching of U, were investigated in order to understand their effect on reagent

A key consequence for gangue minerals, however, is that the strong acid dehydrates polymeric silica in the gangue, thus inhibiting further reaction of the gangue and hence silica dissolution [19,31] under heap leaching conditions. Given that agglomeration/curing takes place with much higher contact of ore and acid, and at higher acid strength than percolating fluids in the heap, reactivity
