For complex phosphate ores, for example, where carbonate minerals are present, it has been difficult to produce high quality phosphate concentrates. Traditional fatty acid collectors not only float the calcium mineral apatite but also the other calcium minerals, calcite and dolomite, explained Kerim Sasioglu, Global Marketing Manager.
The present invention relates to alcoxylated fatty polyamine based collectors for the flotation enrichment of aqueous ore suspensions, and to the use of said alcoxylated fatty polyamine based collectors in flotation processes for ore enrichment, more particularly in reverse flotation processes for the enrichment of ores containing silicates.
Using the mixed fatty acids (MFA) produced by waste cooking oil as flotation collectors directly, the flotation effect is usually not satisfactory, especially at lower temperature, which may be due to the presence of large amounts of saturated fatty acids. In this study, waste cooking oil was separated into saturated fatty acids (SFA) and unsaturated fatty acids (UFA).
This invention relates to a collector composition for the direct froth flotation of nonsulfide ores comprising a) 50 99 wt. % of a mixture of fatty acids and b) 1 50 wt. % of an N acyl derivative of sarcosine of the formula (I) wherein R is a saturated or unsaturated hydrocarbon chain with 7 to 21 carbon atoms, wherein the mixture of comprises 10.0 35.0 wt. % of fatty acid having a saturated
May 23, 1978The use of a secondary alcohol or an ethoxylated secondary alcohol in conjunction with conventional fatty acid in the flotation of non sulfide minerals eliminates or reduces Effective promoter extender for conventional fatty acids in non sulfide mineral flotation Thus, the froth flotation of non sulfide ores with acid collectors
ENHANCED PHOSPHATE FLOTATION USING NOVEL DEPRESSANTS Froth flotation is the most efficient method for phosphate separation, which is a physic chemical separation process based on the difference of surface properties between the valuable minerals and unwanted gangue minerals. However, the presence of clay
Calcium minerals have analogical reactive center and surface reactivity to traditional fatty acid collectors . After primary enrichment by roughing, the classical Petrov process is commonly utilized to further separate scheelite from other calcium minerals .
It enables simple, efficient condition monitoring based on the analysis of vibration signals and process variables. State of the art electronics ensures extremely fast and precise data collection. The GX series analyzers can record up to four measurement channels at the same time (Fig. 2). Fatty acid collectors for phosphate flotation and

1. A process for recovering non sulfide minerals which comprises classifying the mineral to provide particles of flotation size, slurrying the sized mineral in aqueous medium, conditioning the slurry with effective amounts of fuel oil, alkali, and a partial ester of a polycarboxylic acid having at least one free carboxylic acid group, and floating the desired mineral values by froth flotation
disposed as rubbish. The main chemical composition of waste cooking oil is the higher fatty acid glyceride , which can be used to produce anionic fatty acids for mineral otation. Chinas oxide ore otation industry requires more than 800 thousand tons fatty acid collector every year. The traditional
Abstract. At this grinding size, the grain size of the RE minerals ranges from 2 to 40 m, percentage liberation is 922%, and percentage association with nontronite and quartz is 3035%. Results indicated that Sylfat FA2 at 22450 g/t concentration was the more efficient tall oil fatty acid collector at natural pH (pH 7) to basic pH (pH 10.011.5).
Nutrition. Unit 2, Chapter 5 Lipid. STUDY. The fatty acid composition of olive oil is as follows 14% saturated fatty acid, 75% monounsaturated and 17% polyunsaturated. Which of the following is the most likely choice as the monounsaturated fatty acid in olive oil? A healthy digestive tract is this efficient in absorbing triglycerides
These flotation oils can be mixed directly with fatty amine, fatty acid collectors and commercial frothers. The high flash points and modified pour point contribute to better operational safety and efficient flotation over a wide range of operating temperatures. CUC flo Flotation Oil . What is CUC
Feb 06, 1979A collector combination for non sulfide ores comprising from about 1 to about 99 weight percent of a fatty acid derived from a vegetable or animal oil and, correspondingly, from about 99 to about 1 weight percent of a monoester of a sulfosuccinic acid of the general formula ##STR7## wherein R is an alkyl radical of about 4 to 18 carbon atoms

Separation of fluorite and sulfide ore. The sulfide ore contained in fluorite is floated with xanthate collector, and then fatty acid collectors float fluorite. In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite concentrate. Mixed
Principle of operation. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector).
The total and acid soluble copper assays of the tail from Test D were 0.19% and 0.16% Cu, respectively. This shows that the residual copper found in the tail was mainly associated with copper oxide minerals. The total copper, sulphide copper and oxide copper recoveries of 95.5%, 98.2% and 89.4%, respectively.
Results indicated that Sylfat FA2 at 22450 g/t concentration was the more efficient tall oil fatty acid collector at natural pH (pH 7) to basic pH (pH 10.011.5). Flotation at the room temperature (25 C) gave higher selectivity than 40 C temperature flotation.
Existence at least of a slight difference in surface concentration of primary collectors (that adsorb strongerand faster)and in hydrophobicity between minerals. The secondary (weaker) collector (e.g., non ionic) will preferentially Co adsorb on the primary collectors (by hydrophobic chain chain interaction) (RaoandForssberg,1997;Mougdil , 1986))
