Description
Technical field
The present invention relates to the ore dressing and desiliconizing of middle-low bauxite, particularly the diaspore type bauxite dressing process for desiliconizing.
Background technology
The bauxite type of China is mainly based on diaspore type bauxite, have high alumina, high silicon, in the characteristics of low alumina silica ratio.For diaspore type bauxite, the industrial technology that adopt mixed combining method and sintering process to produce aluminium oxide more, investment is big, flow process is complicated, energy consumption is high.In recent years in order to utilize low alumina-silicon ratio alumyte resource in China economically, improve the grade of bauxite by ore dressing and desiliconizing, and then carry out alumina producing with economic Bayer process, become the development trend of effective raising bauxite resource utilization rate, formed ore concentration of bauxite-alumina producing Bayer process technology, wherein the ore dressing and desiliconizing technology of bauxite is the core technology of ore dressing-Bayer process.
In the ore dressing and desiliconizing technology of present existing middle-low bauxite, what generally adopt is to be the regime of agent of flotation water and " heavily drawing weight " (high carbon acid sodium consumption, high score powder consumption, high collector dosage) with new water and part ore dressing backwater, promptly strengthens and disperses to suppress siliceous gangue mineral, reinforcement collecting diaspore.Disclosing the employing calgon among the Chinese patent CN1029547C " a kind of beneficiation method that improves bauxite grade " is that dispersant, certain herbaceous plants with big flowers resin acid are that collecting agent improves bauxite grade, calgon consumption 230-440g/t raw ore, certain herbaceous plants with big flowers resin acid consumption 1350-2250g/t raw ore; Chinese patent CN1163305C, disclose with combined modifier and composite collector in " a kind of beneficiation method of bauxite " and carried out ore concentration of bauxite, sodium carbonate amount 3000-4000g/t raw ore, calgon consumption 60-80g/t raw ore, composite collector consumption 1100-2200g/t raw ore.Sodium carbonate amount, calgon consumption and collector dosage in these two patents are all higher, cause reagent cost higher, and mine tailing and concentrate are difficult to sedimentation, and the purpose mineral easily are suppressed, and make the rate of recovery on the low side.
Summary of the invention
Purpose of the present invention is exactly that reagent consumption height, alumina recovery rate that prior art exists are low in order to overcome in the ore dressing and desiliconizing process of middle-low bauxite, mine tailing and shortcoming such as concentrate sedimentation intractability is big, the floating operation fluctuation is big, and the flotation desilication method of the middle-low bauxite that a kind of ore dressing medicine consumption is low, the water consumption is low, energy consumption is low, desiliconization effect is good is provided.
Method of the present invention is achieved through the following technical solutions.
A kind of flotation desilication method of middle-low bauxite comprises grinde ore, adds the medicament stirring and sizes mixing, and carries out the process of froth flotation; It is characterized in that floatation process adopts is mixed into flotation water with bauxite Bayer stripping condensed water and ore concentration of bauxite backwater, adds adjustment agent, dispersant, collecting agent, is that 4～6 middle-low bauxite carries out flotation to alumina silica ratio A/S.
The flotation water of the inventive method consists of Bayer stripping condensed water and ore concentration of bauxite backwater.The ore dressing backwater comprises concentrate backwater and tailings recycling water, wherein, and stripping condensed water: concentrate backwater: tailings recycling water=0.5～1.5: 4～6: 1.5～2.5.
The floating agent of the inventive method consists of adjusts agent, dispersant and collecting agent, the adjustment agent is a sodium carbonate, dispersant is a calgon, and collecting agent is to be selected from one or more mixture wherein such as oxidized paraffin wax soap, tall oil, aliphatic acid and soap class and derivative etc.
Adjusting the agent sodium carbonate amount is 1000-3000g/ ton raw ore, and the sodium hexametaphosphate dispersant consumption is a 5-100g/ ton raw ore, and collector dosage is a 300-1000g/ ton raw ore.
The present invention is fit to mog-0.074mm 30%-90%, the selected fineness grade scope middle-low bauxite direct-flotation desiliconisation flow process at-0.074mm50%-100%.
Method for floating of the present invention comprises that flotation water is formed, floating agent is formed, consumption comprises that flotation water quality is formed, floating agent is formed, consumption.Learn by laboratory study, the employed inorganic phosphate salt of middle-low bauxite direct-flotation desiliconisation dispersant (especially calgon), peptizaiton is not only arranged in floatation process, and siliceous gangue mineral had concurrently inhibitory action, also purpose mineral diaspore also there is the certain selectivity inhibitory action simultaneously.Because the activated aluminum ion on diaspore surface is a lot, the activated aluminum ion on gangue mineral surface is less, can not influence the absorption of collecting agent when therefore inorganic phosphate salt dispersant dosage is low on the diaspore surface, but be unfavorable for the absorption on gangue mineral surface, make gangue mineral obtain inhibition, and inorganic phosphate salt dispersant dosage is when high, the dispersant cover cap has been lived the part aluminium ion active site on diaspore surface, influenced the absorption of collecting agent on the diaspore surface, thereby the come-up that has suppressed the part diaspore, cause diaspore to enter mine tailing, make the mine tailing alumina silica ratio raise concentrate Al
2O
3The rate of recovery descends.For diaspore type middle-low bauxite direct flotation, adopt the regime of agent of " heavily drawing weight " (high carbon acid sodium consumption, high score powder consumption, high collector dosage), promptly strengthen and disperse to suppress siliceous gangue mineral, reinforcement collecting diaspore, can cause the purpose mineral easily too to be suppressed, make the rate of recovery on the low side, dispersant dosage is too high simultaneously, make that collector dosage also must corresponding raising, caused the mine tailing decentralization high, be metastable suspension, the sedimentation difficulty is big, and concentrate is filtration difficulty then.
Discover by production practices, contain part sodium hydroxide and sodium carbonate in the bauxite Bayer stripping condensed water, pH utilizes alkali wherein can reduce the consumption of adjusting agent more than 8.The condensed water water temperature utilizes it obviously can improve flotation temperature at 70-90 ℃, and the raising of flotation temperature can improve the activation capacity of medicament, thereby reduces the particularly consumption of collecting agent of medicament.Contain a large amount of floating agents in the ore dressing backwater, return flotation and also can significantly reduce reagent consumption.
It is that flotation water, appropriateness disperse to suppress siliceous gangue mineral, effectively utilize the collecting effect that the present invention adopts bauxite Bayer stripping condensed water and ore concentration of bauxite backwater, " gently drawing light pressure " regime of agent with low carbon acid sodium consumption, low dispersant dosage, low collector dosage, make full use of the hydrophobic difference of diaspore and siliceous gangue mineral, overcome the shortcoming that the medicine consumption is high, the water consumption is high, high, the smart mine tailing sedimentation of energy consumption difficulty in filtration is big of middle-low bauxite flotation desilication.
Utilize the present invention can reduce reagent consumption, water consumption and the energy consumption of middle-low bauxite ore dressing and desiliconizing process, effectively improve the alumina recovery rate, alleviate mine tailing and concentrate sedimentation intractability, stable production process, remarkable in economical benefits.
