Definitions

  • the invention relates to the use of alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates based on alkoxylated fatty alcohols as flotation collectors for non-sulfidic ores.
  • Non-sulfidic minerals for the purposes of the present invention are, for example, apatite, fluorite, scheelite and other salt-like minerals, cassiterite and other metal oxides, for example titanium and zirconium oxides, and certain silicates and aluminosilicates.
  • the ore is pre-crushed and dry, but preferably wet-ground and suspended in water.
  • collectors are usually added to the ores, which assist in separating the valuable minerals from the gangue components of the ore. After a certain exposure time, air is blown into the suspension (flotation). It is on the upper surface of the suspension creates a foam.
  • the collector ensures that the surface of the minerals is rendered hydrophobic so that it adheres to the gas bubbles formed during the aeration.
  • the valuable minerals of the ore should preferably adhere to the gas bubbles so that they are stripped off and processed in the form of a mineral-containing foam. It is the task of flotation to extract the valuable mineral in the highest possible yield and at the same time to achieve the best possible enrichment.
  • Anionic and cationic surfactants are mainly used as collectors in the flotative processing of non-sulfidic ores.
  • the collectors should adsorb as selectively as possible on the valuable mineral surface in order to achieve a high concentration in the flotation concentrate.
  • the collectors should develop a stable, but not too stable, flotation foam.
  • Alkyl sulfosuccinates are often used in the flotation of non-sulfidic ores (W. v. Rybinski, MJ Schwuger, "Avemrungstechnik", 26 (1985), page 632 and A. Doren, A. van Lierde and JA de Cuyper, Dev. Min. Proc. 2 (1979), pp. 86-109). In many cases, good flotation results can be achieved with these collectors. In some cases, however, known alkyl sulfosuccinates lead to an undesirably strong development of foam.
  • the present invention therefore relates to the use of alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates which contain one or two identical or different alkyl and / or alkenyl (poly) alkylene glycol ether residues based on propoxylated or propoxylated and ethoxylated, straight-chain or have branched fatty alcohols with a chain length of 8 to 22 carbon atoms, as flotation collectors for non-sulfidic ores.
  • alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates defined above, the abbreviation "sulfosuccinates" is predominantly used below.
  • the alkyl and / or alkenyl radicals of the propoxylated or propoxylated and ethoxylated fatty alcohols which can be used as the basis for the sulfosuccinates preferably have a chain length of 12 to 18 carbon atoms.
  • the fatty alcohol component of the sulfosuccinates can consist of straight-chain and branched, saturated and unsaturated compounds of this category with 8 to 22 carbon atoms, for example n-octanol, n-decanol, n-dodecanol, n-tetradecanol, n-hexadecanol, n-octadecanol , n-eicosanol, n-docosanol, isotridecanol, isooctadecanol, n-hexadecenol and n-octadecenol.
  • the fatty alcohols mentioned can individually form the basis of the sulfosuccinates.
  • products based on fatty alcohol mixtures are used, these fatty alcohol mixtures being derived from the fatty acid component of fats and oils of animal or vegetable origin.
  • such fatty alcohol mixtures can be derived from native fats and oils, including win over the transesterification of the triglycerides with methanol and subsequent catalytic hydrogenation of the fatty acid methyl ester.
  • Both the fatty alcohol mixtures obtained in the production process and suitable fractions with a limited chain length spectrum can serve as the basis for the production of the sulfosuccinates.
  • fatty alcohol mixtures obtained from natural fats and oils synthetically obtained fatty alcohol mixtures, for example the known Ziegler and oxo fatty alcohols, are also suitable as starting material for the production of the sulfosuccinates.
  • the alkyl or alkenyl (poly) alkylene ether glycol residues of the sulfosuccinates each contain at least one propylene glycol ether group.
  • Sulfosuccinates are preferably used whose alkyl or alkenyl (poly) alkylene ether glycol residues have 1 to 6 propylene oxide groups.
  • Addition products of m moles of ethylene oxide and n moles of propylene oxide with fatty alcohols can also be used for the production of the sulfosuccinates, where m and n each represent numbers from 1 to 15, the sum of m and n is 2 to 25 and the ratio of m: n is in the range of 1: 5 to 2: 1.
  • the sulfosuccinates to be used according to the invention can be prepared by known methods of organic synthesis (see, for example, BK Lindner: Tenside-Textilwhisstoff- Waschrohstoffe, Volume 1, Stuttgat 1964, pages 747-748), for example by esterification of the specified fatty alcohol-propylene oxide or fatty alcohol-propylene oxide-ethylene oxide adducts with maleic acid or maleic anhydride and subsequent reaction with sodium sulfite.
  • the sulfosuccinates according to the present invention are added to the raw ore in an amount of 50 to 2,000 g / t.
  • the present invention further relates to a process for separating non-sulfidic ores from the gangue, in which ground ore is mixed with water to form a suspension, air is passed into the suspension in the presence of alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates and separates the resulting foam together with the mineral it contains.
  • the process according to the invention is characterized in that alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates, the one or two, identical or different alkyl and / or alkenyl (poly) alkylene glycol ether residues based on propoxylated or propoxylated and ethoxylated, straight-chain or branched fatty alcohols with a chain length of 8 to 22 carbon atoms, are used as collectors.
  • the process for separating non-sulfidic ores from the gangue is preferably carried out by using the sulfosuccinates in an amount of 50 to 2,000 g / t crude ore.
  • the sulfosuccinates for the purposes of the present invention are particularly suitable for working up Scheelite, Apatite or iron ore.
  • the sulfosuccinates can be present as full and half-esters of sulfosuccinic acid, the half-esters being preferably used. It is also known to the person skilled in the art that the full and half-sulfosuccinic acid esters under consideration here are not used in the form of the free sulfonic acid, but rather as alkali metal and / or ammonium salts, sodium and ammonium salts and in particular mixtures of sodium and ammonium salts being preferred will.
  • alkyl and / or alkenyl (poly) alkylene glycol ether sulfosuccinates based on suitable propoxylated fatty alcohols is that when the sulfosuccinates according to the invention are used, improved collector properties become apparent in the raw ores mentioned.
  • the examples illustrate the more favorable foam properties and the improved collector action of the compounds according to the invention.
  • Example 4 a Na / NH4 salt of a sulfosuccinate based on an adduct of 2 moles of propylene oxide (2 PO) and 1 mole of a mixture of oleyl alcohol (C18; unsaturated) and cetyl alcohol (C16; saturated) was used as the inventive collector as the collector according to the invention used.
  • the flotation tests were carried out using a Humbold-Wedag laboratory flotation machine from KHD Industrieanlagen AG, Humbold-Wedag, Cologne (see Seifen-Fette-Wachsen 105 (1979), p. 248) in a 1 l flotation cell.
  • Deionized water was used to make the slurry.
  • the cloud density was 400 g / l.
  • Water glass with a dosage of 2,000 g / t was used as the pusher.
  • the conditioning time of the pusher was 10 minutes at a stirring speed of 2,000 l / min. It was floated at the pH value of approximately 9.5 resulting from the addition of water glass.
  • the type of collector dosage is shown in Table 2.
  • the conditioning time of the collector was 3 minutes.
  • the collector according to Example 4 achieves a significantly higher output of WO3 and a considerably better concentration in the concentrate than with the collector according to Comparative Example 3.
  • a Brazilian apatite ore was floated, which in addition to silicates also contained iron oxides as gangue minerals.
  • the ore had the following composition: approx. 21% P2O5 12% Fe2O3 26% SiO2
  • the grain size distribution of the task is: ⁇ 40 ⁇ m 21% 40 - 100 ⁇ m 38% 100 - 250 ⁇ m 35% > 250 ⁇ m 6%
  • a Na / NH4 salt of a sulfosuccinate based on an adduct of 2 moles of propylene oxide with 1 mole of oleyl cetyl alcohol in combination with tall oil fatty acid was used as the collector according to the invention.
  • the weight ratio of sulfosuccinate to tall oil fatty acid was 1: 1, in example 6 2: 1.
  • Comparative Example 4 a combination of a Na salt of an alkyl sulfosuccinate based on oleyl cetyl alcohol and tall oil fatty acid in a weight ratio of 2: 1 was used as the collector.
  • the collector consisted of a mixture of a Na / NH4 salt of an alkyl sulfosuccinate based on oleyl cetyl alcohol and tall oil fatty acid in a weight ratio of 1: 1.
  • the flotation tests were carried out in a laboratory flotation cell (model D-1 from Denver Equipment with a capacity of 1 liter) at room temperature. Tap water with a hardness of 16 ° dH was used to produce the slurry. The turbidity was 500 g / l and the pH was adjusted to 10.5 with sodium hydroxide solution before the collector was added.
  • the waste from iron ore processing with the following composition (main components) was floated: approx. 12% P2O5 36% SiO2 14% Fe2O3 15% CaO
  • the very rough flotation task had the following grain size distribution: ⁇ 25 ⁇ m 5% 25 - 100 ⁇ m 15% 200 - 500 ⁇ m 70% 500 - 1,000 ⁇ m 9% > 1 000 ⁇ m 1%
  • Example 7 the collector consisted of a Na / NH4 salt of a sulfosuccinate based on an adduct of 1 mol of propylene oxide (1 PO) and 1 mol of oleyl cetyl alcohol.
