Description

Beschreibungdescription
Flotationsreagenz für SilikateFlotation reagent for silicates
Die vorliegende Erfindung betrifft die Verwendung von Sammlern in der flotativen Aufbereitung von silikathaltigen Mineralen und Erzen, insbesondere Eisenerz mit Hilfe von Fettalkyletheralkylaminalkoxylat.The present invention relates to the use of collectors in the flotation treatment of silicate-containing minerals and ores, in particular iron ore with the aid of fatty alkyl ether alkylamine alkoxylate.
Viele natürlich vorkommende Erze und Mineralien enthalten Silikat als unerwünschtes Begleitmineral. Hierzu zählen neben Eisenerz Calcit, Phosphaterz und Feldspat. Insbesondere beim Eisenerz mindert der Silikatgehalt die Qualität des Eisenerzes und stört bei der Eisenherstellung. Um hochqualitatives Eisenerz zu gewinnen, ist es von Interesse, den Silikatgehalt des Eisenerzes auf unter 2 % zu senken, üblicherweise wird das Eisenerz neben der magnetischen Separierung durch inverse Flotation vom Silikat getrennt. Hierzu wird das aufgemahlene Eisenerz in einer Flotationszelle mit Wasser und Flotationsreagenzien zusammengebracht, wobei das Silikat durch den Einsatz eines Sammlers mit dem Schaum ausgetragen wird, während das Eisenerz zurück in der so genannten Trübe verbleibt.Many naturally occurring ores and minerals contain silicate as an undesirable companion mineral. In addition to iron ore, these include calcite, phosphate ore and feldspar. Especially with iron ore, the silicate content reduces the quality of the iron ore and interferes with iron production. In order to obtain high-quality iron ore, it is of interest to reduce the silicate content of the iron ore to below 2%, usually the iron ore is separated from the silicate in addition to the magnetic separation by inverse flotation. For this purpose, the ground iron ore is brought together in a flotation cell with water and flotation reagents, wherein the silicate is discharged through the use of a collector with the foam, while the iron ore remains back in the so-called pulp.
Als Silikatsammler werden beispielsweise Fettamine, Alkyletheramine und Alkyletherdiamine eingesetzt. Diese sind unter dem Handelsnamen Flotigam® bekannt.For example, fatty amines, alkyl ether amines and alkyl ether diamines are used as silicate collectors. These are known under the trade name Flotigam ®.
Alkyletheramine und Alkyletherdiamine werden zumeist in deren teilneutralisierten Formen als Teilacetate eingesetzt wie in US-4 319 987 beschrieben. Grund hierfür ist die bessere Löslichkeit der teilneutralisierten Aminfunktionen.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 the better solubility of the partially neutralized amine functions.
US-6 076 682 beschreibt die kombinierte Verwendung von Alkylethermonoamin mit Alkyletherdiamin zur Silikatflotation aus Eisenerz.US Pat. No. 6,076,682 describes the combined use of alkylethermonoamine with alkyletherdiamine for the silicate flotation of iron ore.
In WO 00/62937 wird die Verwendung quaternärer Amine zur Flotation von Eisenerz offenbart. In WO-93/06935 wird die synergistische Wirkung von Etheraminen und anionischen Sammlern zur Eisenerzflotation beschrieben.WO 00/62937 discloses the use of quaternary amines for flotation of iron ore. WO-93/06935 describes the synergistic effect of ether amines and anionic collectors for iron ore floatation.
Die Silikatflotation, u.a. aus Eisenerz, unter Zuhilfenahme von Alkyloxyalkanaminen wird in US-5 540 337 beschrieben.The silicate flotation, u.a. from iron ore with the aid of alkyloxyalkanamines is described in US-5,540,337.
Die im Stand der Technik beschriebenen Sammler für die Silikatflotation zeigen jedoch unzureichende Selektivität und Ausbeute. Aufgabe vorliegender Erfindung war es daher, einen verbesserten Sammler für die Silikatflotation bereitzustellen.However, the silicate flotation collectors described in the prior art show insufficient selectivity and yield. The object of the present invention was therefore to provide an improved collector for the silicate flotation.
Überraschenderweise wurde gefunden, dass die Verwendung von Fettalkyletheralkylaminalkoxylaten zu einer deutlichen Verbesserung der Silikatflotation aus Eisenerz gegenüber den bekannten Flotationsreagenzien führt.Surprisingly, it has been found that the use of fatty alkyl ether alkylamine alkoxylates leads to a marked improvement in the silicate flotation of iron ore over the known flotation reagents.
