Abstract
The invention discloses an alumyte flotation compound collecting agent which is characterized by being composed of 5-15 wt% of industrial grade monocarboxyl fatty acid, 20-55 wt% of alkyl hydroximic acid and 30-65 wt% of alkyl alcohol. The invention strengthens the selective collecting capability of the collecting agent by introducing in the hydroximic acid and improves the intersolubility of each component in the compound; synergism between components causes the compound collecting agent to easily disperse evenly in ore pulp, simultaneously improve collecting effect and bring good resistance to low temperature. The compound collecting agent can directly and effectively float alumyte without desorbing fine silt.
Description
Technical field
The present invention relates to the composite collector that a kind of bauxite flotation is used.
Technical background
Bauxite is the raw material of industry of alumina producing, and aluminum oxide industry requires the alumina silica ratio (A/S) of bauxite high as far as possible; Especially the bayer process that has characteristics such as efficient height, energy consumption is low, flow process is simple, production cost is low requires the alumina silica ratio of bauxitic feed materials greater than 8 especially.External main bauxite manufacturer is general to adopt simple washup, desliming can produce qualified Bayer process raw material.But, the bauxite resource of China be mostly in low-grade diaspore type bauxite, general alumina silica ratio can't be produced qualified Bayer process raw material by simple washup, desliming technology about 4.This class bauxite resource can be deviate from siliceous mineral by floatation, thereby improves the alumina silica ratio of concentrate.
At present, the flotation desilication method for bauxite of China's commercial Application is a direct flotation, direct-flotation desiliconisation process using fatty acid (as oxidized paraffin wax soap, tall oil, oleic acid, linoleic acid) and derivative of fatty acid etc. or their mixture be as collecting agent, adopts wherein a kind of such as sodium carbonate, NaOH, calgon, waterglass or several to adjust agent; Collector dosage is generally 1500-3500 gram/ton raw ore.
Collecting agent is the key factor that influences the bauxite flotation desiliconization, the problem of collecting agent such as fatty acid and derivative of fatty acid in bauxite direct-flotation desiliconisation production mainly contains: the poor selectivity of floatation process, the flotation froth thickness, to the bad adaptability of ore character, cause aluminium mineral and siliceous mineral separation difficulty, the concentrate rate of recovery low; When ore character changes, when especially clay content increases, the control difficulty of floatation process, even be difficult to guarantee concentrate quality; In addition, the low temperature adaptability of this class collecting agent is poor, and the consumption under cryogenic conditions significantly increases, even can't use, and ore pulp need be heated and handle more than 20 ℃, could realize that aluminium mineral effectively separates with siliceous mineral, and this will cause beneficiation cost significantly to increase.
Therefore, strengthen the selectivity collecting ability of collecting agent, improve the adaptability of collecting agent ore character and production environment, for improve the mineral dressing and silicon removal of bauxite index, save energy and reduce the cost, reduce production costs significant.
Summary of the invention
The objective of the invention is in low-grade bauxite direct-flotation desiliconisation technology collecting agent poor selectivity, to the adaptability of ore change of properties strong and shortcoming such as low temperature adaptability is poor, the flotation desilication effect is undesirable, a kind of bauxite flotation composite collector is provided.
The present invention is achieved by the following technical solutions.
A kind of bauxite flotation composite collector, it is characterized in that forming by mono carboxylic aliphatic acid, alkyl hydroximic acid and the alkylol of commercial grade, be by mass percentage: 5%～15% mono carboxylic aliphatic acid, 20%～55% alkyl hydroximic acid, 30%～65% alkylol.
Described mono carboxylic aliphatic acid has following structure:
Wherein R represents the alkyl that 6-20 carbon atom formed.
Described alkyl hydroximic acid has following two kinds of structures:
Wherein R represents the alkyl that the 5-12 carbon atom is formed.
Described alkylol has following structure:
R-OH
Wherein R represents the alkyl that 2-10 carbon atom formed.
Flotation composite collector provided by the invention, mono carboxylic aliphatic acid, alkyl hydroximic acid and alkylol by commercial grade are formed, according to certain percentage compound after, after fully dissolving dispersion with the NaOH of its gross mass 20%-50% or sodium carbonate again, as the collecting agent that bauxite direct-flotation desiliconisation is used, collector dosage is technology routinely.The direct-flotation desiliconisation of bauxite such as low-grade diaspore type, boehmite type or three boehmite types in being applicable to; Also can be used as diaspore type, boehmite type or three boehmite type selective flocculant for bauxite and realize separating of aluminium mineral and siliceous mineral.
The present invention is by introducing the selectivity collecting ability that hydroximic acid strengthens collecting agent, introduce the intersolubility that alkylol improves each component in the compound, synergistic function between each component is uniformly dispersed composite collector easily in ore pulp, improve the collecting effect simultaneously and have the good low-temperature resistance performance.This compound collecting agent can directly floatingly select bauxite effectively under the situation that does not remove thin mud.
The specific embodiment
A kind of bauxite flotation composite collector is made up of mono carboxylic aliphatic acid, alkyl hydroximic acid and alkylol, and its mass percent is: 5%～15% mono carboxylic aliphatic acid, 20%～55% alkyl hydroximic acid, 30%～65% alkylol.
