Influence of aluminum–sodium silicate on olivine flotation ...

2019-11-01  The flotation recoveries of olivine are approximately 80% without the addition of sodium silicate, after which the olivine recovery decreases gradually and reaches 54.6% at a Na 2 SiO 3 dosage of 0.70 mM. With the increase in the dosage of sodium silicate, the recovery of olivine decreases.

Selective flotation of ilmenite from olivine using the ...

2016-12-10  The micro-flotation results indicate that the AWG at a molar ratio 1:3 of oxalic acid to water Limestone (WG) exhibits the maximum selective depression on olivine. The selective flotation of ilmenite from olivine can be better achieved using an AWG as depressant rather than WG in the artificially mixed minerals flotation experiments.

Olivine - an overview ScienceDirect Topics

Geologically relevant olivines belong to a solid solution between two end-member phases: forsterite (Fo) Mg2 SiO 4 and fayalite (Fa) Fe 2 SiO 4. The structure of olivine is based on a distorted h.c.p. oxygen sublattice. The Bravais lattice is orthorhombic and the unit cell contains four formula units.

2015-03-01  The flotation behaviors of ilmenite, titanaugite, and forsterite using sodium oleate as the collector were investigated using microflotation experiments, zeta-potential measurements, Fourier transform infrared (FT-IR) analyses, X-ray photoelectron spectroscopy (XPS) analyses and the artificially mixed minerals flotation experiments.

Olivine flotation and settling experiments on the join ...

Olivine flotation and settling are rapid in a time period of only a few hours because viscosities are a little greater than that of paraffin oil at room temperature. Some adcumulate textures with good triple junction grain boundaries are developed. General observations of differentiated magmatic systems on a number of scales and experimental data indicate that the mechanisms by which magmas ...

2014-08-20  Abstract As a pretreatment method, microwave irradiation was applied to modify ilmenite surface properties and to improve its flotation behavior in the presence of different gangue minerals including olivine, pyroxene, tremolite, clinochlore and quartz.

Flotation of Chromite as Pre-Treatment of Olivine Before ...

Flotation using G30 Milled olivine and serpentine allows enrichment ratio of 1.25 to 1.5 only in the first half of the flotation test. Chromite separation from GL10 olivine, which is the finest mineral was observed to be of nil efficiency. Because a significant fraction of particles is below 20 µm in olivine GL10 and GL30 Milled, mineral particles can be entrained with little effect of zeta ...

FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES

Olivine, iron oxides and talc have been identified as minor minerals. Adequate degree of liberation of chromite was obtained by grinding the ore to minus 180µm. Froth flotation was used to upgrade this chromite ore. Oleic acid was used as collector. Several operating parameters influencing the floatability of the Sudanese chromite ores were investigated. These include the collector and ...

Behavior of a perched crystal layer in a magma ocean ...

The liquid in the lower cell becomes more olivine-rich and more Fe-rich because of partial melting, increasing the buoyancy and thermal stability of the crystal layer. However, melting and physical disruption will still occur. Forcing must cease when a subsolidus lid to the magma ocean is established. The perched layer is now destroyed by melting, but the neutral point remains a site of heat ...

A long-lived magma ocean on a young Moon Science Advances

A giant impact onto Earth led to the formation of the Moon, resulted in a lunar magma ocean (LMO), and initiated the last event of core segregation on Earth. However, the timing and temporal link of these events remain uncertain. Here, we demonstrate that the low thermal conductivity of the lunar crust combined with heat extraction by partial melting of deep cumulates undergoing convection ...

Olivine is not fibrous or anisotropic, has an isoelectric point close to that of pentlandite, and the interaction between olivine and pentlandite is strongly repulsive . Thus, the negative effects of serpentine on grinding and flotation, including slime coating, froth dilution by fiber-bubble aggregates, and high viscosity, should be reduced or eliminated by serpentine dehydroxylation.
