) are two typical minerals in gangue.16−18 In the flotation process, these gangue minerals may enter into clean coal products through coating or entrainment. Numerous studies have been carried out to explore the adverse effectsof the nonselective flotation behavior of gangue minerals in the flotationprocess.19−23 However, the associations ...

If the internal atomic arrangement is lacking, then it is an amorphous substance. A rock is generally composed of various minerals and if the rock contains valuable minerals frOm which metals can be extracted at a profit, it is called an 'ore'. The unwanted mineral in an ore is called gangue (i.e., generally rock forming minerals). For ...

The main mineral component of coal gangue is clay minerals which are ingredients to meet brick production requirements. The energy in coal gangue functions in the process of brick making to realize the save of raw coals. In addition to the need of coal gangue to be crushed, the other production process is basically the same as that of clay …

Gangue minerals are mainly nonmetallic minerals, but also include metal minerals that have no comprehensive utilization value due to their low content, such as pyrite, galena, and sphalerite in copper ores. The proportion of ore minerals and gangue minerals varies with ore types and with rich and poor mineral grades in the same ore.

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …
