investigation the influence of the temperature of liquid phase on quality of recycled waste newspaper and on efficiency in removing the ink from newspaper by flotation.
Flotation separation is mainly used for removing particulates from aqueous dispersions. It is widely used for ore beneficiation and recovering valuable materials. This paper reviews the hydrodynamics of flotation separations and comments on selected recent publications.
Ion flotation as an adsorptive separation technique has recently received a sharp increase in research activities. This process is a simple and effective method for separation and removal of metallic ions from wastewaters.
Recent investigations indicated that using nanobubbles (NBs) in flotation separation of fine particles (25 μm) has several advantages; however, a detail study on performances of various flotation parameters (such as hydrodynamic variables and particle properties) and their impacts on recovery of coarse particles (100 μm) in the presence of

The optimization of arsenic separation by dissolved air flotation requires thoughtful consideration of the arsenic separation, flotation, kinetic parameters, kinetic flotation models Sorption flotation, part of adsorptive bubbles Investigations on the separation equilibrium and kinetic
In separation of valuable minerals from gangue minerals, reagents are added to the flotation process on the basis of the difference in their surface properties. Action of flotation reagents depends on several factors, including the natural composition of the mineral surface, the alkalinity, acidity of the medium and pulp temperature.
A free jet flotation column gives good selectivity and high separation efficiency in treating fine and ultra-fine coal. This paper reports test results of coal desulfurization with a free jet flotation column.
Eriez is world authority in magnetic separation technologies. Since 1942, Eriez provides a range of permanent and electromagnetic separators for many industries.
separation process of solid products, by establishing a contact in three phases the floating mineral, the A series of investigations on the flotation of coals at different stages of metamorphism and with various characteristics of fine slimes was carried out. The effect of aerohydrodynamic
Magnetic separation method was used for concentration of non-magnetic minerals, especially copper bearing minerals, from iron minerals. As a result, copper grade increased up to 0.18% and its recovery reached 86%. acid leaching flotation Investigation of the possibility of copper recovery from the flotation tailings by acid leaching
The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult.

Experimental results obtained in this investigation demonstrated that effective separation of bitumen from high-grade Utah tar sands can be achieved with a hot-water process, involving the addition of wetting agents, digestion of the tar sand under high shear conditions, and finally separating the bitumen from the sand by a modified froth flotation technique.
SOLID-LIQUID SEPARATION olid-liquid separation is concerned with mechanical processes for the separation of liquids and finely S divided insoluble solids. 11.1. PROCESSES AND EQUIPMENT Much equipment for the separation of liquids and finely divided solids was invented independently in a number of industries and is of diverse character.
A flotation pre-treatment study for the separation of enargite (Cu 3 AsS 4) from chalcopyrite (CuFeS 2) ores of different origins was investigated in this work.The copper ore bearing enargite mineral contained 5.87 mass% As and 16.50 mass% Cu while the chalcopyrite bearing ore contained 0.32 mass% As and 21.63 mass% Cu.
