Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means water loving and …
Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal.

able mineral particles from the undesired gangue mineral particles. The bubble}particle aggregates move up in the cell by buoyancy and are removed from the cell lip into an inclined drainage box called a launder (Figure 1). The launder product is com-monly known as concentrate. The particles that do not attach to the bubbles are discharged out ...
Coal gangue is a complex industrial solid waste mixed with organic compounds, inorganic compounds and minerals (Fabiańska et al. 2013).Its major chemical compositions are SiO 2, Al 2 O 3 and Fe 2 O 3, with traces of CaO, P 2 O 5, MgO and MnO 2.The chemical composition of coal gangue from various sources and its comparison with soil reference …

The presence of this gangue mineral suggests that the flotability of the PGMs in this sample would be quite poor [24,52]. These gangue minerals can depress the flotation of the valuable PGM-bearing minerals, leading to low recoveries in a conventional flotation circuit. The silicate and oxide minerals dominate the mineralogy of chromite tailings.
Ore sorting is a useful tool to remove gangue material from the ore and increase the quality of the ore. The vast developments in the area of artificial intelligence allow fast processing of full-color digital images for the preferred investigations. The associated gangue minerals from limestone and coal mines were identified using three different approaches. All …

Dense medium separation (DMS) or heavy media separation is a pre-concentration technique used to reject gangue minerals before grinding. DMS exploits the difference in specific gravity between the target and gangue minerals, commonly used in processing diamond ore, and is also used in the separation of spodumene from other gangue silicates.. Such as: The specific …
