Description
Technical field
The invention belongs to the efficient technique of rainwater utilization field of mineral resources, relate in particular to a kind of for
iron ore andfloating agent of multiple oxide ore ore beneficiation and its preparation method and application.
Background technology
Mineral resources belong to disposable resource, have non-renewablely, due to exploitation utilization for many years, all kinds of ore deposits abundant ore source reduces day by day in the world, but due to industry, agricultural and the increase of other industry to disposable mineral resources demand, it will be more and more important utilizing lean ore and difficult ore dressing.The most ore resources of China generally have the feature of " poor, thin, assorted ", impurity content is high simultaneously, and high-quality " ore fine fodder " is with a wide range of applications and wide market prospects, this is objectively requiring ore dressing plant to select rational collecting agent and floatation process thereof to produce phosphorus concentrate, thereby realize maximum economic interests, economize on resources.Moreover, high-quality " concentrate " is also significant to smelting to produce.With ironmaking, data shows, feed grade raising 1%, and pig iron output can improve 2.5%, and coke ratio reduces by 1.5%.Carry Fe and reducing Si and fall and assorted can make beneficiation cost slightly increase, but can increase substantially ironmaking benefit, the benefit of associated industry is increased.In addition, the impurity such as other mineral concentrate sulphur, phosphorus, arsenic are low, all have to smelting the effect that generally promotes economic benefit, and ore dressing can make ore dressing plant and smelting company obtain doulbe-sides' victory with smelting by reasonable prices mechanism.It is for Mineral Processing Enterprises that concentrate is purified again or smelting enterprise all has economic benefit.
Except the reason of economic benefit aspect, high-quality external ore resources has also formed huge pressure to domestic metallurgical mine enterprise.China iron deposit stone resource is poor, particularly compares with Australia with Brazil of iron ore leading exporter, and the iron ore resource of China has following obvious deficiency: 1. average head grade is lower; 2. the ratio of rich ore is on the low side; 3. SiO
2content higher; 4. phosphorous, the sulphur of iron ore, arsenic exceed standard; 5. a large amount of iron-containing tailings select rate low again, serious waste of resources.These unfavorable factors are had higher requirement to mineral processing in China worker.Mineral processing in China worker must constantly strengthen upgrading and fall the research that assorted (especially carry Fe and reducing Si, carry iron fall phosphorus, carry iron and fall sulphur) and iron-containing tailing select again, the self-produced iron ore concentrate of Cai Nengshi China overcomes inadequate natural endowment, with the competition of external iron ore in form competitive advantage.
In order to improve the quality of iron ore concentrate, China's iron and steel mine adopted magnetic separation iron ore reverse floatation process more one after another in recent years, to reduce the content of concentrate free silica etc.Require to improve constantly the capacity factor of a blast furnace to strengthen today of self competitiveness at steel industry, metallurgical mine enterprise application reverse floatation process strengthens iron ore concentrate to carry Fe and reducing Si, carry iron and fall assorted (fall phosphorus, fall sulphur, fall arsenic, spoil reclaming), and this tool is of great significance.
At present, the technique that silicon falls in iron ore reverse flotation has two kinds: a kind of is the anion reverse floatation technique growing up from high intensity magnetic mineral reverse flotation, and this technique obtains more general application in China; Another kind is cation reverse flotation technique, and industrially developed country generally adopts cation reverse flotation technique.Although China adopts anion reverse floatation technique can obtain good separation index, but flotation temperature high (flotation of need heating), energy consumption is large, uses pharmacy variety many (needing to use inhibitor, adjusting agent, activator, collecting agent etc.), this causes medicament expense with too high, concentrate filtration difficulty.And the cation reverse flotation collecting agent of application is mainly amine collector at present, comprise fatty amine and ether amine.According to hydrogen in amine molecule by other alkyl (being mainly methyl) replace quantity number be divided into primary amine, secondary amine, tertiary amine, quaternary amine, and according to containing amido content in amine molecule number be divided into monoamine and diamine.Amine collector development is slower, and it is compared with anion reverse floatation collecting agent, and amine collector separating effect is also relatively poor, and the foam of formation is sticky, does not have anion reverse floatation easily to control sorting in process.
In order to promote better the development of reverse floatation process, must strengthen the Optimization Work to reverse floatation agent and technique.Strengthen application study to anion reverse floatation technique, medicament that anion reverse floatation is had is simple, be conducive to filtering means dehydration.
In addition; along with iron ore and some special ore species resources reduce and the continuous attention of country to environmental protection, resource reutilization, people start to pay attention to some discarded research and development and production application work of reclaiming iron and phosphorus, rare earth, tungsten, bismuth, molybdenum, titanium, fluorite etc. containing iron ore (as lead-zinc smelting mine tailing, copper metallurgy tailings, pyrite cinder, soak the tailings such as gold) and low-grade phosphate ore, Rare Earth Mine, fluorite ore, tungsten ore, ilmenite etc. originally.Therefore, innoxious, the energy-conservation environmental protection of beneficiation reagent and multiple-effect, efficient, wholesomeness also seem particularly important.Strengthen the research work to green non-poisonous, pollution-free, degradable medicament and carry out synthetic development and the application study of the beneficiation reagents such as high-efficiency anion collecting agent, all tool is of great significance.
But up to now, the Mineral Processing Enterprises of China mostly continues to use aliphatic acid and amine ionic water soluble medicament carries out ore dressing.Due to fatty acid soaps class bad dispersibility in ore pulp, the ore pulp that therefore usually needs the to heat flotation of heating, energy consumption is high.And cationic medicament is very responsive to sludge, mineral processing index is unstable.
Therefore, research and develop a kind of beneficiation reagent that can overcome above-mentioned technological deficiency, realized environmental protection, energy-saving and emission-reduction, energy-saving and cost-reducingly there is for a person skilled in the art important theory significance and actual promotional value.
