Minerals Special Issue : Flotation Advances in Mineral and
Special Issue Information. Dear Colleagues, Flotation is a very efficient unit operation employed worldwide to separate valuable minerals from gangue materials (this is called froth flotation) and in the treatment of wastewaters as a solid (liquid) water separation, removing several pollutants. This issue covers the advances in these two areas.In the flotation of a copper sulfide ore with magnesium aluminum silicate used as gangue minerals, tests on the relationship between the rheological property of the flotation pulp and the flotation kinetics have found that, when the viscosity coefficient of the flotation pulp increased from 0.002 Pas to 0.02 Pas (at the same time the yield stress Minerals Free Full-Text A Brief Review of Micro-Particle MDPI

Minerals Free Full-Text A Review of Flotation Physical Froth
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the As a pre-treatment method of refractory gold ore, carbonaceous matter (C-matter) flotation was investigated with multi-stage flotation by rougher, scavenger, and cleaner stages. Different dosages of kerosene and MIBC (4-Methyl-2-pentanol) were applied and the optimum dosage was selected by testing in each flotation stage.

Experimental Research and Practice of Mineral Separation from Flotation
The high-ash tailings produced by flotation contains a large number of minerals that can be recycled. However, as the separation and purification technology for flotation tailings is not mature and separation efficiencies are low, it is generally treated as separation waste, resulting in the waste of mineral resources. In view of this The TON Concorde Cell™ sets a new benchmark in high intensity pneumatic flotation by recovering unachievable fine and ultra-fine ColumnCell™.

CDF simulation of bubble-particle collisions in mineral flotation cells
The efficiency of the flotation process depends highly on the initial contact between the air bubble and the mineral particle. To enhance this contact, flotation cells are designed to achieve goodGraphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy.

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind The small-scale phenomena most critical to the operation of a flotation cell are the interactions between particles and bubbles, so these should be the prime focus for multi-scale modelling.
