The results of bench scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect of water hardness, in addition to other parameters, are discussed.
The same flotation reagents used in a traditional way provided much worse concentrates containing 27 wt. P 2 O 5 with recovery of 60 wt. at 0.9 kg Mg of reagents. References 1 A.

Jul 26, 2010 Dolomite Introduces Advanced Droplet Generation System Published Jul 26, 2010 Royston, UK (26th July 2010) – Dolomite, a world leader in microfluidic design and manufacture, has introduced the modular Droplet Advanced System, which enables users to produce than 10,000 highly monodispersed droplets per second, ranging from 20 to 250 m.
Due to the different ore properties, the dosage range of flotation reagent is also different. Even for the same type of ore, there are also some differences in the formation of ore deposit, so the content of useful minerals and gangue vary, and the dosage of flotation reagent required in the flotation.

Mar 22, 2007 The flotation of aqueous solutions (1 l) of calcite, dolomite and gypsum was performed at pH 6.0, by 1.5 mg l −1 Co and 0.6 mmol l −1 HMDTC −. To minimise the effect of the reaction between Ca Mg, which restrains the function of the surfactant, careful selection of the most suitable foaming reagent was necessary.
Modifiers are necessary to improve flotation selectivity. It was found that sodium silicate selectively depressed magnesite at a pH of 4.5 to 7.5. The flotation mechanism was investigated by characterizing surface electrical properties and measuring the adsorption density of the reagents on magnesite and dolomite.
While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The order of addition of flotation reagents appeared very Important for achieving a high recovery of Iowa coal.

A froth flotation method is disclosed for separating fine particles of fossil resin from by use of frothing reagents which include an aliphatic organic compound having a polar group and containing not than four carbon atoms. Butanol is an effective frothing reagent in this method.
2018 (English) In Minerals, ISSN 2075 163X, E ISSN 2075 163X, Vol. 8, article id 354 Article in journal (Refereed) Published Abstract [en] It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite.
Flotation Process For Antimony Ore 「antimony ore flotation moroco」 antimony ore processing equipments flotation process antimony ore beneficiation is the most effective method for the selection and metallurgy of niobium metal at present, there are mainly three methods of hand selection, gravity separation and flotation among them, the flotation process is the most reliable.
This study presents a compilation of various parameters, including zeta potential, pH, particle size, reagents (collectors, depressant, and modifiers), and bio flotation, which were examined in several investigations into separating Mg carbonates from their AVMs by froth flotation. Keywords dolomite magnesite flotation bio flotation 1.
Oct 11, 2017 Reverse flotation of coal can be explained as a process where valuable minerals are depressed, while undesired and unhealthy minerals are floated with the help of some reagents. Nowadays, conventional enrichment method of coal could not achieve removing unhealthy minerals partially from internal structure of coal such as sulfur, Hg, Au, which propagate in air after burning.

Dolomite, and quartz in single mineral flotation and artificial mixture flotation with dodecylamine (DDA) as collector. The results showed that while the pH, dissolved ions, and competitive adsorption had a minor influence on their floatability, fine magnesite and dolomite largely decreased the.
Based on the properties of the ore, flotation feasibility study was conducted. Results show that concentrate with excellent test indexes that a Ag grade of 4787.31 g t with a Ag recovery of 87.97 and a Cu grade of 6.01 with a Cu recovery of 87.92 were obtained under the used process and reagent system conditions.
An ore containing small amounts of columbium bearing minerals is beneficiated by froth flotation, an aqueous pulp of the ground ore being floated in the presence of a cationic collector of the amine type, a surface active agent and a modifying agent providing a source of free oxalate ions from the group consisting of oxalic acid and oxalate salts.

May 12, 2020 Froth flotation is the most effective industrial method used to separate fine grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores.
Dolomite is the main host rock. The orebodies are stratiform and lenticular, with masses, bands, layers, veins, and disseminations. Very large Rare Earth elements (REE) Fe Nb deposit (Bayan Obo type), discovered as an iron deposit.
Oct 07, 1975 What we claim is 1. A process for beneficiating by froth flotation an ore containing small amounts of the columbium bearing mineral pyrochlore and large quantities of gangue materials, including large quantities of carbonates from the group comprising dolomite, ankerite, calcite and siderite, which comprises grinding said ore to a small particle size suitable for separation of the columbium.
