Description
Technical field
A kind of beneficiation method of bauxite relates to the ore dressing of bauxite, particularly diaspore type bauxite ore dressing.
Background technology
Mineral dressing and silicon removal of bauxite has found an effective way for low alumina-silicon ratio alumyte reasonable resources utilization in China, has effectively improved the utilization rate of bauxite resource.The ore dressing and desiliconizing technology of bauxite is the core technology of ore dressing-Bayer process, and the ore dressing production capacity of bauxite has directly restricted production capacity and production cost that subsequent oxidation aluminium is produced.
In the traditional ore dressing of various ores is produced, in comprising that ore concentration of bauxite is produced, the flotation cell number of each flotation operation is more than 2, same flotation operation all adopts be to the ore deposit ore pulp from first groove in order successively the ladder direct current to last groove, froth pulp under the effect of floating agent in the ore pulp separates with product in the groove, after each groove foam blows into or flow automatically to same foam tank by scraper plate, enter next flotation operation again and further sort.
Bauxite forward flotation comprise roughly select, coarse scan, selected I, selected II, essence sweep five subjobs.For roughly selecting-the selected II-concentrate of selected I-, the foam of coarse scan enters to be roughly selected its foam trend in proper order, and the foam that essence is swept enters selected I.Roughly select with refining process in, flotation initial stage flotation speed is fast, therefore the foam float-amount of former grooves is very big, and the solid particle A/S that is with of institute is higher, along with the prolongation of flotation time, afterwards a few groove foams are with solid particle A/S progressively to reduce then.Usually roughly select foam and be with solid particle A/S6～11, selected I foam is with solid particle A/S7～12, and selected II is with solid particle A/S11～16, and selected II foam finally obtains product-flotation concentrate by being behind the froth breaking in concentrate hopper.Will cause like this first groove roughly selected or former grooves the foam that scrapes can reach the requirement of selected II with solid particle A/S; First groove of selected I or the foam that scrapes of former grooves can reach the requirement of concentrate with solid particle A/S, but flow process also must be by primary cleaning II operation, the foam volume that causes system to shift is very big, because bauxite flotation concentrate productive rate height (about 80%), foam volume is original just very big, when a froth pulp flows not smooth, groove usually appears emitting, clogging, make operation control difficulty increase, the floatation indicators fluctuation, the floating agent waste, the process loss increases, because the fluctuation variation can appear in head grade inevitably, also make the control of floating operation and concentrate grade difficult more in addition.
Summary of the invention
Method of the present invention is exactly at the deficiency of above-mentioned prior art in the flotation existence of bauxite, a kind of beneficiation method that can effectively overcome the bauxite that big, thick, the selected foam of prior art foam volume in bauxite flotation is mobile not freely, flotation operation operation control is difficult, floatation indicators fluctuates greatly, the process loss is high, flotation operation production capacity is low, medicine consumes high shortcoming is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of beneficiation method of bauxite comprises that the bauxite raw ore is levigate, roughly selecting after sizing mixing, coarse scan, selected I, selected II, essence sweep five floatation process, it is characterized in that:
(1) the short circuit pipeline that enters selected II groove, concentrate hopper is set in roughly selecting foam tank, when the initial separatory cell foam was with solid particle A/S to reach 9～11, the short circuit of initial separatory cell froth flotation thing entered selected II groove; When the initial separatory cell flotation froth is with solid particle A/S to reach 11＜A/S＜16, roughly selects the short circuit of froth flotation thing and enter concentrate hopper, directly as concentrate;
(2) enter the short circuit pipeline of concentrate hopper in the setting of selected I groove, when selected I groove flotation froth was with solid particle A/S to reach 11＜A/S＜16, the direct short-circuit of selected I groove flotation froth entered concentrate hopper, directly as concentrate.
The beneficiation method of a kind of bauxite of the present invention is characterized in that being provided with the movable flashboard that is used to isolate in the middle of its short circuit pipeline, and material adopts to be opened the flashboard gravity flow or use pumping mode.
The floating agent kind that adopts among the present invention is identical with conventional floating agent, for example the bauxite forward flotation medicament is: wherein a kind of of oxidized paraffin wax soap, tall oil, aliphatic acid and soap class and derivative etc. or several are made collecting agent, and wherein a kind of such as sodium carbonate, NaOH, polyphosphate, waterglass, small organic molecule or several adjust agent.
Method of the present invention is applicable to the flotation of A/S4～6, can obtain the concentrate of A/S11～16.
The flotation froth of the inventive method is with solid particle A/S to be less than 9, still need roughly select during flotation operation, coarse scan, selected I, selected II, essence sweep floatation process five subjobs, and the final products foam obtains concentrate by froth breaking.
The present invention has adjusted and has roughly selected, the trend of selected flotation operation foam, and control is roughly selected foam and is with solid particle A/S6～9, and selected I foam is with solid particle A/S9～11, and selected II foam is with solid particle A/S11～16, forms rational ore dressing gradient.According to the needs of final products concentrate A/S, reach the foam that A/S requires with selected flotation operation and directly change corresponding flotation operation over to roughly selecting.
Adopt the present invention that the flotation froth trend is rationally adjusted, the flotation disposal ability improves 10%-40% when making bauxite flotation, and technical process is simple, processing ease, and reagent consumption reduces 10%-40%.
