Description
Technical field
The present invention relates to a kind of applied in any combination of iron ore reverse flotation medicament, especially the method that is used in combination that relates to iron ore anion reverse flotation desulfurizing and silicon reducing agent, what can be widely used in that magnetic iron ore selects that factory, bloodstone select factory carries the iron desulfurizing and silicon reducing, also can be used for limonite, martite and half martite desulfurizing and silicon reducing flotation.
Background technology
Iron ore is carried Fe and reducing Si both can adopt anion reverse floatation, also can adopt cation reverse flotation, more in industrial application with anion reverse floatation at present, and technology is also comparatively ripe.Sulphur also more or less freely sorting under the prior art equipment falls in single iron ore flotation.A kind of method that is used in combination of iron ore anion reverse floatation agent is disclosed as Chinese patent ZL01117501, it is that fine grinding is reached the iron ore that basic monomer dissociates, the ore pulp of furnishing suitable concentration, at first add the cornstarch stirring of adjusting after agent NaOH stirs, adds and then the inhibitor saponification, and then adding activator CaO stirs in ore pulp, add collecting agent at last and fully stir, it is characterized in that the industrial oleic acid after flotation collector adopts saponification, and four kinds of medicaments are used in combination.Advantage of the present invention is: the floating agent unit consumption is low, has reduced cost, has improved sorting result.
If but the iron ore iron selection technique should fall silicon with the method for reverse flotation, desulfurization does not again also have example at present at home and abroad.
The difficulty of iron ore anion reverse flotation desulfurizing and silicon reducing is how to use method for floating separation of iron mineral and sulfur mineral.Because the sulfur mineral in the ore mainly exists with the pyrite form, beneficiation method routinely, the floating agent of employing is ethyl xanthate and 2# oil.And the method that iron mineral separates with sulfur mineral has two kinds, a kind of is to select iron mineral to select sulfur mineral before earlier, but because 2# oil frothing capacity is strong, medicament itself is also longer action time, select the medicament that remains in the ore pulp behind the sulphur to select the silicon operation to impact to follow-up flotation, occur chats at the scene in the actual production and return the phenomenon that foam is more, be difficult for froth breaking, and along with chats constantly returns, the foam that swims in the ore pulp surface is difficult for eliminating, the foam volume of roughly selecting operation is increased, the selectivity variation of medicament, assorting room are affected, and finally have influence on iron concentrate grade.Second kind is to select sulfur mineral after selecting iron mineral earlier, owing to select the starch that adds in the iron process, pyrite is had inhibitory action, and the sulphur in the iron ore concentrate is difficult to remove.
Therefore, carry the iron desulfurizing and silicon reducing, need to explore new sulfur method for iron ore reverse flotation, also desulfurization when carrying Fe and reducing Si, thus reach the purpose that reduces sulfur impurity content in the iron ore concentrate.
Summary of the invention
Purpose of the present invention is exactly the problems referred to above that exist at prior art, and provide a kind of method that is used in combination of iron ore anion reverse flotation desulfurizing and silicon reducing agent, this method can be when iron ore be carried Fe and reducing Si, remove objectionable impurities sulphur in the iron ore concentrate, final iron concentrate grade height, the objectionable impurities sulfur content is low.
For realizing above-mentioned purpose of the present invention, the method that is used in combination of iron ore anion reverse flotation desulfurizing and silicon reducing agent of the present invention by the following technical solutions:
Fine grinding is reached the iron ore that basic monomer dissociates, close choosing acquisition iron ore rough concentrate through magnetic separation or magnetic reconnection, the rough concentrate that obtains is adopted anion reverse flotation desulfurizing and silicon reducing, its medicament kind and consumption (calculating for the ore deposit dry basis by flotation) are:
Desulfurizing agent: ethyl xanthate 80-100g/t;
PH adjusts agent: NaOH 950-1150g/t;
Iron mineral inhibitor: starch (writing a Chinese character in simplified form DF) 450-600g/t;
The activator CaO:320-420g/t of quartz or silicate;
Anion reverse floatation collecting agent: 600-750g/t.
Its best dosing (calculating for the ore deposit dry basis by flotation) is:
Desulfurizing agent: ethyl xanthate 88-92g/t;
PH adjusts agent: NaOH 1030-1080g/t;
Iron mineral inhibitor: DF500-540g/t;
The activator CaO:380-400g/t of quartz or silicate;
Anion reverse floatation collecting agent: 650-700g/t.
The best processing route that the method that is used in combination of iron ore anion reverse flotation desulfurizing and silicon reducing agent of the present invention adopts is one roughing, recleaning, scans for three times
Medicament adding mode is: the activator CaO that adds desulfurizing agent ethyl xanthate, PH adjustment agent NaOH, iron mineral inhibitor DF, quartz or silicate in the section of roughly selecting; The anion reverse floatation collecting agent then adds respectively in the section of roughly selecting, primary cleaning section, recleaning section respectively, at the 70%-80% of the section of roughly selecting adding anion reverse floatation collecting agent total amount, add the 10%-15% of anion reverse floatation collecting agent total amount respectively in primary cleaning section, recleaning section.
Described anion reverse floatation collecting agent is the saponified fat hydrochlorate, also can be the polyfunctional group carboxylate, as the MD series anionic collecting agent in reverse floatation of selling on the market, its acid number (mgKOH/g) 90-210, saponification number (mgKOH/g) 90-210, iodine number: 100～120.
The starch that adopts is cornstarch, and the best is the causticization cornstarch.
After the present invention adopts technique scheme, on the iron ore concentrate desulfurization method, important breakthrough is arranged, only use pyritous collecting agent ethyl xanthate, and utilize the frothing capacity of anion collecting agent MD, with pyrite and silica emersion together.In addition, in sweetening process, do not add 2
#Oil need not consider that a large amount of foams that the oils foaming agent produced to selecting the influence of iron process, have reduced reagent cost, has simplified technological process, and this method is easy to implement aborning.
The specific embodiment
For further describing the present invention, the method that is used in combination of iron ore anion reverse flotation desulfurizing and silicon reducing agent of the present invention is described further below in conjunction with embodiment.
The test sample ore is taken from domestic certain large-scale iron ore.The chemical multielement analysis of raw ore and iron material phase analysis the results are shown in Table 1 and table 2.From table 1, table 2 as can be seen, main valuable mineral is a hematite-limonite in the ore, is martite secondly, and the iron occupancy volume of magnetic iron ore is less, only account for 2.08 percentage points, and the iron of hematite-limonite accounts for 84.68 percentage points, belongs to the refractory iron ore thing.Major impurity is SiO in the ore
