Definitions
- the present invention relates to the use of collectors in the flotation of iron ore containing magnetite and / or hematite.
- iron ore include calcite, phosphate ore and feldspar.
- the silicate content reduces the quality of the iron ore and interferes with iron production.
- the iron ore is separated from the silicate in addition to the magnetic separation by inverse flotation.
- silicate collector for example, fatty amines, alkyl ether amines and
- Alkyletherdiamine used. These are known under the trade name Flotigam ®.
- Alkyl ether amines and alkyl ether diamines are mostly used in their partially neutralized forms as partial acetates as described in US Pat. No. 4,319,987. The reason for this is their better solubility in the pulp.
- WO 00/62937 discloses the use of quaternary amines for flotation of iron ore.
- WO-93/06935 the synergistic effect of ether amines and
- Alkyloxyalkanamines are described in US 5,540,337.
- the subject of the present invention is thus the use of a
- A, B independently of one another are a C 2 - to C 5 -alkylene radical
- R is a Cs to C2 4 alkyl or alkenyl radical
- R 2 , R 3 , R 4 independently of one another are H or a C 8 - to C 24 -acyl radical, with which
- radicals R 2 , R 3 or R 4 is a C 8 - to C 24 -acyl radical
- x, y, z are independently an integer from 0 to 50 with the
- Hydrocarbon radical having 1 to 50 carbon atoms which may contain either an oxygen atom or an oxygen atom and a nitrogen atom, in amounts of 10 to 5,000 g / ton as a collector in the inverse flotation of iron ore containing magnetite, hematite or both.
- Another object of the invention is a method for the inverse flotation of iron ore containing magnetite, hematite or both, by a
- A, B independently of one another are a C 2 - to C 5 -alkylene radical
- R 1 is a C 8 - to C 2 alkyl or alkenyl radical
- R 2 , R 3 , R 4 independently of one another are H or a C 8 - to C 24 -acyl radical, with which
- radicals R 2 , R 3 or R 4 is a Ca- to C 24 -acyl radical
- x, y, z are independently an integer from 0 to 50 with the
- Hydrocarbon radical having 1 to 50 carbon atoms which may contain either an oxygen atom or an oxygen atom and a nitrogen atom, in quantities of 10 to 5,000 g / ton iron ore brings into contact with the iron ore.
- the composition of A) and B) is also referred to below as
- A) and / or B) can be used as shown or in the form of their salts, which are obtainable by reacting A) and / or B) with acids, for example acetic acid or hydrochloric acid.
- the ratio of the collector components A: B is preferably between 98: 2 and 2:98 by weight, in particular between 70:30 and 30:70 by weight.
- the collector according to the invention is free of quaternary ammonium compounds which comprise at least one organic radical containing 8 to 36 carbon atoms and bound to the ammonium nitrogen atom, optionally containing heteroatoms.
- a quaternary ammonium compound is meant a compound which does not carry a hydrogen atom on the ammonium nitrogen atom, but in which the
- Ammonium nitrogen atom is bonded to four carbon atoms.
- This particularly preferred embodiment is therefore not to be understood as the embodiment in which either the compound of the formula 1 or the compound B) of the formula D-Nh or both are present as mono- or diammonium salts.
- These mono- or diammonium salts carry at least one hydrogen atom on the ammonium nitrogen atom.
- component B) can be used as a salt, for example as an acetate.
- component B) of the collector according to the invention is
- R 7 and R 8 one or more aliphatic radicals
- Hydrocarbon group having 2 to 4 carbon atoms correspond;
- R 1 preferably represents a linear or branched alkyl or alkenyl group comprising 10 to 22 carbon atoms. Particularly preferred for R 1 are isodecyl isotridecyl, dodecyl, Cocosfettalkyl- and Talgfettalkylreste.
- R 1 in a preferred embodiment represents an alkyl and alkenyl chain cut derived from coconut oil fatty acid, palm oil fatty acid, tallow fatty acid, oleic acid, tall oil fatty acid or rapeseed oil fatty acid.
- R 2 , R 3 , R 4 are each independently acyl radicals with 8 to
- the acyl radicals preferably comprise 10 to
- acyl radicals can be saturated or unsaturated.
- Preferred acyl radicals are stearoyl and
- R 6 , R 9 , R 13 independently of one another preferably represent a linear or branched alkyl or alkenyl group having 8 to 18 carbon atoms.
- R 6 , R 9 , R 13 are 2-ethylhexyl, isononyl, isodecyl and Isotridecyl- and dodecyl.
- R 5 , R 7 , R 8 independently of one another preferably represent alkylene groups having 2, 3 or 4 carbon atoms, in particular ethylene or propylene groups.
- A is in particular either an ethylene - (- C 2 H 4 -), a propylene - (- C 3 H 6 -) or a butylene group (-C 4 Hs-).
- A is an ethylene group.
- B is in particular either an ethylene - (- C 2 H 4 -), a propylene - (- C 3 H 6 -) or a butylene group (-CH 8 -).
- B stands for one
- x, y and z preferably give an integer of 15 to 30, in particular 20 to 25.
- the aminoalkoxylate ester constituting component A) is in the form of its mono- or di-ammonium salts obtained by neutralization with both organic and mineral acids.
- flotation reagent according to the invention can also be carried out in combination with foaming agents and pushers, as known from the prior art.
- foaming agents and pushers as known from the prior art.
- iron ore is carried along with it, preferably hydrophilic polysaccharides, such as, for example, modified starch, carboxymethylcellulose, or gum
- Arabic added in dosages of 10 to 1,000 g / t as a pusher.
- the silicate flotation is preferably carried out at a pH of 7 to 12, in particular 8 to 1, which is set, for example, with sodium hydroxide.
- the following table represents the flotative results of the inventive collector compared to the standard reagent. Flotation experiments were carried out on an iron ore containing magnetite and hematite.
- Decyl group, R 7 and R 8 are a propyl group
- R 1 coconut fatty alkyl
- R 2 oleoyl
- R 3 oleoyl
