Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this …Web

The smelter-grade alumina for aluminum production is mainly produced by the Bayer process. Nearly the entire aluminum industry worldwide has adopted the Bayer process for alumina production from bauxite ore [].This process generates nearly 1.0 to 1.5 tons of red mud or bauxite residue (BR) as a byproduct per ton of alumina produced, …Web

The Miocene Climatic Optimum (MCO) represents a global warm period (approximately 17–14.7 Ma) interrupting a long-term period of Cenozoic cooling. To elucidate if bauxitization took place in southeastern European mid-latitude areas during the MCO, we studied a section of undated massive karst bauxite (Crveni Klanac, CK) in central …Web
