Serpentine mineral Britannica

Serpentine, any of a group of hydrous magnesium-rich silicate minerals. The composition of these common rock-forming minerals approximates Mg3Si2O5(OH)4. Serpentine generally occurs in three polymorphs: chrysotile, a fibrous variety used as asbestos; antigorite, a variety occurring in either

The flotation separation of galena and pyrite using

Jan 15, 2019· Serpentine, a common gangue mineral encountered in complex sulfide ores, has been found to be an efficient depressant for ferric sulfide (e.g., pyrite). Serpentine was tested as a potential selective depressant in the differential flotation separation of galena and pyrite using potassium butyl xanthate (PBX) as a collector.

Serpentine subgroup Wikipedia

The serpentine subgroup (part of the kaolinite-serpentine group) are greenish, brownish, or spotted minerals commonly found in serpentinite rocks. They are used as a source of magnesium and asbestos, and as a decorative stone. The name is thought to come from the greenish color being that of a serpent. The serpentine group describes a group of common rock-forming hydrous magnesium iron

Serpentinite Wikipedia

Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group, which are rich in magnesium and water, light to dark green, greasy looking and slippery feeling, are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from

Perovskite CONCENTRATION OF MINERALS

Uses: A minor ore of titanium and rare earth metals and as mineral specimens. Perovskite is a calcium titanium oxide mineral composed of calcium titanate, with the chemical formula CaTiO 3. The stability of perovskite in igneous rocks is limited by its reaction relation with sphene. In vol canic rocks perovskite and sphene are not found together.

Separation of Chromite from Serpentine in Fine Sizes using

In this study, possible separation of chromite from serpentine in fine sizes using a magnetic carrier was investigated as a function of pH, dodecylamine (DDA) dosage, and amount of magnetite. First, the zeta potentials of minerals were determined in the absence and presence of DDA, and then magnetic carrier experiments were performed in

Serpentine Hiker's Notebook

Common Name: Serpentine “Serpent-like” is an allusion to the colors of a snake’s skin; green and gray is the hues of the predominant mineral combinations although whites and yellows may also be present. The rock that contains serpentine minerals is serpentinite. Scientific Name: Magnesium silicate Mg3Si2O5 (OH) 4 Potpourri: Serpentine is a mineral that

Bioleaching of serpentine group mineral by fungus

Many studies of serpentine group mineral dissolution for mineral carbonation have been published in recent years. However, most of them focus mainly on either physical and chemical processes or on bacterial function, rather than fungal involvement in the bioleaching of serpentine group mineral. Due to the excessive costs of the magnesium dissolution process, finding a lower energy consumption

Separation of light hydrocarbons by gas chromatography

The application of serpentine ore (brownish colour) as a stationary phase for the separation of hydrocarbons by gas-solid chromatography has been tested. Separation of methane, ethane, propane, n-butane, iso-butane and acetylene has been accomplished at room temperature (25°C). The separated components were detected with a flame ionization

Effect of sodium hexametaphosphate on separation of

separation of serpentine from sulfide ore in the flotation of the serpentine-bearing sulfide ore, especially in the flotation of the copper-nickel sulfide. The main gangue mineral has a much higher content of serpentine, and it is prone to being clayed, which seriously interferes with the flotation of nickel-containing minerals[1−8]. In order for
