Centrifuge-assisted piston cylinder experiments were conducted on plagioclase in basaltic melt at 1140–1250 °C, 0.42–0.84 GPa and mostly 1000 g. One set of experiments assesses the settling velocity of a dilute plagioclase suspension; a second sinks or floats plagioclase in a MORB-type melt exploring conditions of neutral buoyancy; and a third set examines floatation of plagioclase from ...

Investigations into the Recovery of Platinum Group ...

In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of ...

Olivine: A rock-forming mineral. Used as the gemstone peridot.

Olivine is the name of a group of rock-forming minerals that are typically found in mafic and ultramafic igneous rocks such as basalt, gabbro, dunite, diabase, and peridotite. They are usually green in color and have compositions that typically range between Mg 2 SiO 4 and Fe 2 SiO 4. Many people are familiar with olivine because it is the ...

Copper Nickel Flotation

The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed …

Chromite Flotation - 911 Metallurgist

Olivine Group. The flotation behavior of olivine using a sulfonate is shown in Figures 9 to 12. With a sulfonate collector, olivine floats strongly only in acidic pulps. The extent of the maximum recovery region increases as. the pH decreases up to the point where the solid begins to decompose. The isoelectric point of olivine is about 4.1.

UNDERSTANDING OLIVINE CO2 MINERAL SEQUESTRATION …

Carbonation of the widely occurring mineral olivine (e.g., forsterite, Mg{sub 2}SiO{sub 4}) is a large-scale sequestration process candidate for regional implementation, which converts CO{sub 2} into the environmentally benign mineral magnesite (MgCO{sub 3}). The primary goal is cost-competitive process development.

Concentration - LKAB

After grinding, separation and flotation, various additives are mixed with the slurry, such as olivine, quartzite, limestone and dolomite – depending on product specification and pellet type. The slurry is then filtered until it achieves a predetermined moisture content. When the concentration of the ore is complete, it is time for pelletisation.

Magnesioferrite

Unlike the silica of olivine, the calcium silicate phases block or slow the diffusion of magnesia into the iron oxide portions of these burden materials. Magnesioferrite, then, continues to form in these burden materials during the reduction process. The phase expansion associated with this leads to swelling and cracking of pelletized burden ...

Why Pine Oil Is Used In Froth Floatation Process? - BYJU'S

In the froth floatation process, pine oil is used because it attracts the impurities from the ore. Also, the chemical constituents of pine oil that is cyclic terpene alcohols make it hydrophobic thereby reducing the affinity of pine oil towards the water. Stay tuned with BYJU'S to learn more about other concepts.
