Organophilic substance clay, wherein montmorillonite type (smectite-type) clay with tetraalkyl ammonium salt for example Chlorodimethyl-two (C14-C18 alkyl) ammonium carries out ion exchange, is known and it has been found that as oil-based composition Thickener.They are particularly useful as the additive of oil base drilling fluid, to prevent particle (such as drilling …

Barite (BaSO4) and celestite (SrSO4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO42H2O) or anhydrite (CaSO4). Barite, despite having a broader geological distribution is rarely present in these deposits.

For barite flotation the various co llectors were tested: sulfidezid cotton oil-soap stock, soaps of fatty acids and alkyl sulphates of C12 – C16 row, among the "Baritol" is the most efficient one. Depression of the barren rock was carried out by liquid glass in alkaline medium. The effect of pulp pH on barite flotation has been investigated.

High-grade fluorite and barite samples were collected from the Wuling mountain area, China. The purities of fluorite and barite were over 97% based on X- ray diffraction (XRD, Fig. 1) and X-ray fluorescence (XRF) spectrometer analysis ().It can be seen that the characteristic peaks of fluorite and barite samples corresponded quite well to the standard …

3、Flotation Flotation are used to separate the fine-grained dissemination barite and tailings from gravity separation. According to different adsorption type, use fatty acid alkyl sulfate, alkane sulfonate, etc anion collector or kation amine collector to flotine barite.

Baryte used for drilling petroleum wells can be black, blue, brown or gray depending on the ore body. The baryte is finely ground so that at least 97% of the material, by weight, can pass through a 200-mesh (75 μm) screen, and no more than 30%, by weight, can be less than 6 μm diameter.

The development of new collectors to separate fluorite from barite is urgently needed in mineral processing. In this study, the flotation behavior of fluorite and barite was studied using sodium ...

As a common salt mineral, the barite flotation process can be divided into two types according to the form of adsorption: one is to use fatty acid alkyl sulfate, alkyl sulfonate and other anion collectors to adsorb on the surface of barite mineral in the form of chemical adsorption, so as to separate from the other associated minerals.

As for the barite with fine particle size and gravity tailings, HOT Mining applies process of flotation. According to the different adsorption manner, HOT Mining uses some anionic collector, like fatty acid alkyl sulfate, alkyl sulfonate, or cationic collector, like amide collectors to do the flotation for barite ore. Case Study:

Baryte is a mineral consisting of barium sulfate (BaSO4). baryte is generally white or colorless and is the main source of barium. The barite group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba, Sr)SO4.

Where a long-chain alkyl ammonium cation is also incorporated as explained hereinbelow, this may be added along with the mixture of reactants fed to the pug mill at the same time. Subsequent to the production of the adduct, it may be used as such, or it may be dried, with or without subsequent grinding.

Abstract The degree of flocculation of fine barite suspensions in aqueous alkyl sulfate solutions at 25 ± 2°C depended on sulfate concentration, on alkyl chain length and on whether the Krafft point for the particular sulfate was higher or lower than 25°C. For C 14 -C 8 sulfates, whose Krafft point was higher than this temperature, not only was the maximum flocculation achieved at …

I'm working on beneficiation of barium sulfate from low grade barite ore (64.2% BaSO4) in presence of 28.01 SiO2 and 4.8 PbO. 4.8% PbO with 28% SiO2. We want to achieve min 4.2 S.G with less than 250 ppm Lead. (OCMA Standard) Does anyone have any experiences on such ore. What is the common barit
