Abstract
The present invention is a kind of regime of agent that utilizes floatation process method purification magnesite ore.When being characterized in using amine to pounce on receiving agent to remove magnesite impurity, add an amount of inorganic phosphate, improve separating effect by reverse floatation process.Like this magnesite ore is only carried out a reverse flotation processing and can reach the present technical indicator of handling to reach with reverse flotation-direct flotation process integration.Simplified present magnesite ore flotation process.Kind, quantity, equipment investment and the administrative expenses of floating agent have been reduced.Make production cost reduce by 50%～60%.Help the conveying of reverse flotation froth pulp and improve the recycling water utilization rate of magnesite flotation mill.
Description
The present invention is a kind of regime of agent that utilizes floatation process method purification magnesite ore.
At present, comprise high-purity magnesite concentrate, often adopt floatation to remove the objectionable impurities mineral of calcic, silicon and the iron of association in the magnesite ore, as dolomite, calcite, various silicate and quartz for to obtain the higher magnesite concentrate of quality.Usually the floatation process that adopts is: at first with fatty amine or aromatic amine compound as pouncing on the receipts agent, remove the quartz and the part silicate mineral of association in the magnesite ore with inverse flotation method, and then with fatty acid compound as pouncing on the receipts agent, be used various inhibitor and remove dolomite, calcite and part silicate mineral with the direct flotation method.When with above-mentioned aminated compounds as pouncing on the receipts agent, when utilizing inverse flotation method purification magnesite ore, amine pounce on receive agent to the effect of magnesite and dolomite, calcite and part silicate all a little less than, difference between the floatability of valuable mineral magnesite and objectionable impurities mineral is little, thereby can not effectively remove impure mineral in the magnesite ore, also often improved in magnesite and the rough concentrate calcium content ， And and to some silicate to pounce on adduction also not so good.When using above-mentioned technology and regime of agent in addition, technology is complicated; Medicament kind is more.Need during direct flotation ore pulp is heated, for production operation and management are made troubles, because technology and regime of agent are complicated, for the backwater comprehensive utilization of magnesite flotation mill brings difficulty.
The present invention proposes a kind of regime of agent of adjusting agent that adds for addressing the above problem.In the reverse flotation process, add an amount of inorganic phosphate (comprising various orthophosphates, metaphosphate, Quadrafos and pyrophosphate), improved the pounce on receipts ability of aminated compounds, and the floatability of the floatability of magnesite when not adding inorganic phosphate is basic identical to dolomite, calcite and silicates mineral.Thereby strengthened the effect that the reverse flotation process is sloughed the objectionable impurities mineral of calcic, silicon and iron.Reverse flotation-direct flotation process integration that regime of agent of the present invention only needs reverse floatation process to reach to adopt at present usually just can reach sorts technical indicator (concentrate grade and the valuable mineral rate of recovery).
Particular content of the present invention is described below: using fatty amine and aromatic amine compound as pouncing on the receipts agent, when utilizing the reverse floatation process method to remove impurity in the magnesite ore, add an amount of inorganic phosphate (comprising orthophosphates, metaphosphate, Quadrafos and pyrophosphate) as adjusting agent.For obtaining the best technical-economic index that sorts, need determine the suitable amounts and the optimum PH value range of the various medicaments of use when using regime of agent of the present invention according to other magnesite ore character to be selected, when handling raw magnesite, pounce on the consumption of receiving the agent aminated compounds and be generally 50g/T～300g/T, the consumption of inorganic phosphate is generally 50g/T～500g/T, and medium pH value scope can be between 3～10.Inorganic phosphate can join in the surge tank, also can be added in grinding machine or the flotation device, has strengthened amine by adding adjustment agent and has pounced on the pounce on adduction of receipts agent to dolomite, calcite and some silicate impure minerals; Improved separating effect; Improved the technical-economic index that utilizes floatation purification magnesite ore.
Adopt the technology of regime of agent of the present invention to compare, have following superiority with traditional magnesite floatation process:
1. can reduce by 60% flotation device, reduce the capital expenditure of magnesite flotation mill.
2. can reduce the value volume and range of product of floating agent, cut down the consumption of energy and reduce the site administrator, can make the cost of producing magnesite concentrate per ton reduce by 50%～60%.
3. can increase the flowability of reverse flotation froth pulp, make it easy to handle and carry.
4. can improve ore dressing plant backwater level of comprehensive utilization after the work simplification.
Below by embodiment the present invention is specifically described: use regime of agent of the present invention, adopt reverse flotation small-scale test technology that one-level magnesite fine ore is carried out sorting test.Concrete experiment condition is: in hydrochloric acid and after lauryl amine consumption 150g/T, sodium hexametaphosphate consumption 200g/T(or sodium dihydrogen phosphate 250g/T, or sodium pyrophosphate 250g/T).Adjust medium pH value to 4～6 with technical hydrochloric acid.Order of addition of ingredients is as follows: hydrochloric acid, inorganic phosphate, lauryl amine.At first sorted 4.0 minutes, and obtained productive rate and be 25%～28% true tailings, and then flotation can to obtain productive rate in 3.5 minutes be that 40%～45% final concentrate and productive rate are 27%～35% chats, the technical indicator of raw ore and various products sees the following form:
