Description
Technical field
The present invention relates to a kind of iron tailings ore dressing flotation technology, specifically, relate to a kind of ilmenite ore dressing flotation medicine.
Background technology
The content of titanium is 6/1000ths left and right of earth crustal mass, approximately 3,400,000,000 tons of world savings.In ore, sand grains, clay, coal, oil, plant, natural water, there is the distribution of titanium.World Titanium ore resources be take ilmenite as main, and ilmenite accounts for 90% of World Titanium total resources, and reserves mainly concentrate on the states such as China, Australia, South Africa, India; All the other are 10% from rutile, anatase, Iron-ore Slag etc., and reserves mainly concentrate on the states such as Australia, South Africa, India, Brazil, Ukraine and the U.S..
Ilmenite concentrate is the raw material of producing titanium dioxide and titanium sponge.Within 2010, China's titanium white powder output has reached 1,000,000 tons, and titanium sponge annual production reaches 2～30,000 tons.Calculate accordingly, China produces titanium dioxide the demand of ilmenite concentrate is about to 2,400,000 tons, and producing titanium sponge is 5～70,000 tons to the demand of ilmenite concentrate.This shows, China is larger to the market capacity of ilmenite concentrate.Shandong District is contained abundant ilmenite resource, and the titaniferous iron selection tailings of nearly ten million ton, and in district, the natural type of ilmenite ore is mainly magnet hornblend lithotype, TiO in iron selection tailings
2content is generally 5%～10%, TFe content and is generally 15%～20%.
Ilmenite is in the process of flotation, and medicament plays very important effect, and it directly concerns the flotation quality of ilmenite.People since 20th century four the fifties just to ilmenite, flotation is studied, initial, for the conventional medicament of ilmenite flotation, have fatty acid, as oxidized paraffin wax soap class, spent pulping liquor and tall oil, hydroximic acid and its esters, organic phospho acid and swollen acid etc.Due to poor, the refinement of ore, the floating agent of those ilmenites can not meet the needs of industrial development far away before, and therefore, people start the feature for this class ore of present stage, carry out particular study, constantly release novel medicament.At present, main ilmenite floating agent has collecting agent, adjusting agent, foaming agent etc.
Common titaniferous ore has ilmenite, rutile, perovskite and aspidelite.Their floatability is as follows:
Ilmenite (FeTiO
3) and rutile (TiO
2) with carboxylic acid and amine collector, can swim.But during with carboxylic acids collecting, gangue mineral is difficult for swimming, therefore carboxylic acids is used morely.Industrial conventional concrete medicament has oleic acid, tall oil and naphthenic acid and soap thereof.And conventional kerosene is supplementary catching agent.Before ilmenite and Rutile Flotation, first use sulfuric acid scrubbing mineral surfaces, can improve their floatability, reduce the consumption of collecting agent.
During with carboxylic acid collecting ilmenite and rutile, pH=6-8, two kinds of mineral all swim relatively goodly.In the acid medium of pH<5, be adsorbed in the easy wash-out of oleic acid on ilmenite surface, after washing, the floatability of ilmenite significantly declines.
Prodan and sodium fluoride can hinder tridecanoic acid and enuatrol in the surperficial set of ilmenite, reduce them in the fixed amount on ilmenite surface, thereby can suppress ilmenite, and sodium metasilicate also has certain inhibitory action for ilmenite.
The rate of recovery of ilmenite flotation flocculation and dispersity of ore particle when adjusting is relevant.If adjust the power consumption of groove power transmission shaft and the relation curve of the time of adjustment, can be divided into double teacher by large young pathbreaker's adjustment time of its power consumption, i.e. phase of sensitization, flocculation stage, flocculation crest stage, flocculation failure stage and scatter stage.
When slurry starts to flocculate (flocculation stage), net work consumption, the ilmenite rate of recovery and the gangue rate of recovery all rise; Arrive the flocculation crest stage, ore pulp fully flocculates, and net work consumption, the ilmenite rate of recovery and the gangue rate of recovery have all reached summit; Arrive flocculation failure stage, the rate of recovery of ilmenite is constant, and concentrate grade increases, and net work consumption and flocculation decline toward degree; Arrive scatter stage, concentrate grade declines, and the rate of recovery is minimum.
Rising slurry temperature, the hydrophobicity of collecting agent film increases, and the rate of recovery of ilmenite increases and concentrate grade decline.Inflation titanium, zirconium ore thing have obvious impact.Fill air 60-120s, the rate of recovery of rutile and ilmenite all rises and the rate of recovery decline of zirconium English.If be only filled with nitrogen, two kinds of titanium minerals are suppressed and zircon can swim as usual.
Perovskite (CaTiO
3) can first use sulfuric acid treatment, after rinsing, with oleic acid or other aliphatic acid, swim.Soda and waterglass can suppress it, and chromate and bichromate can activate it.When calcite is many in ore, can make the consumption of pickling increase.In order to reduce sour consumption, before floating perovskite, can first float calcite.
Aspidelite CaTiSiO
5can, with the oleic acid collecting of emulsification, can be suppressed by waterglass.Its floatability is poor compared with other titaniferous ores, poorer than alkaline-earth metal salt mineral such as apatite, if the apatite of association can first float apatite at most.
The frequent association of dressing method ilmenite, rutile and zircon of titanium lead ore, density is all at 4.0-4.7g/cm
3between, while sorting with gravity separation method, they enter in heavy sand simultaneously.Their floatability is also very approaching, and during with the flotation of emulsification oleic acid, they enter in people's bulk concentrate simultaneously.Their bulk concentrate has two kinds of separation methods in principle:
(1) first by magnetic method, separate ilmenite (magnetic separation also can be placed on flotation after), its nonmagnetic portion suppresses zircon with prodan, with emulsification oleic acid flotation rutile in the medium of pH=3.8-4.6.
(2) with sulfuric acid, suppress rutile, with emulsification oleic acid or cation-collecting agent flotation zircon.
Yet total some place not fully up to expectations of use of this single medicament, does not reach better effect, relies on existing floating agent, is difficult to TiO in iron tailings
2content is brought up to more than 40%.
