Minerals Special Issue : High Gradient Magnetic Separation
Special Issue Information. Dear Colleagues, Modern high-gradient magnetic separation was initially triggered in the early 1930s. In the recent several decades, it has become one of the key technologies in the exploration of weakly magnetic ores, such as oxide irons, ilmenite, wolframite, and manganese, and in the removal of Herein, the importance of physical separation methods of ores in mineral processing is widely acknowledged.

Minerals Free Full-Text Extraction of Nickel from Garnierite
In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing is the process of separating commercially valuable minerals from their ores.

Wastewater Treatment in Mineral Processing of Non-Ferrous
Almost 2 × 10 9 t of minerals (including ores of almost all non-ferrous metals, e.g., sulfide and oxide ores of copper, lead, and zinc) are processed by flotation each year around the world . Organic collectors and regulators are widely used when non-ferrous metal ores are subjected to the flotation process [ 70 ] to achieve reasonable Based on the relationship between ionic radius and electronegativity, isomorphic replacement between Sn 2+ /Fe 2+ and Sn 4+ /Fe 3+ easily occurs; hence, tin is regarded as a siderophile element according to Goldschmidt’s rules.1,7,8 Therefore, cassiterite is always associated with iron-bearing minerals.

Chemical separation of iron ore ScienceDirect
Major impurity elements in iron ore are silicon, aluminum, phosphorus, and sulfur. Often, a chemical separation is the only method able to remove phosphorus from iron ores. Phosphorus can occur as phosphorus-containing minerals (e.g., apatite) and being finely dispersed in hematite in oolitic ironstones or in goethite in goethite–hematiteAt present, the separation methods used for copper–cobalt sulfide ores include the following: Duan et al. improved the recovery rate of copper–sulfur minerals by changing the reagent system.

Minerals Free Full-Text Mineralogical Factors Affecting the
Dense medium separation (DMS) is often used to reject a large portion of gangue material upfront to create cost and energy savings during processing. As lower-grade ores with complex mineralogy are being increasingly exploited, the properties of the gangue minerals begin to play a more important role in the upgrading of the ore. It is Mineral liberation, which is related to the particle size, is also a parameter in the froth flotation of phosphate ores. Fine grinding is critical to attain greater liberation but will unfavorably affect the separation efficiency. Therefore, there is generally a compromise when choosing the particle size.Review of the Main Factors Affecting the Flotation of Phosphate Ores
