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 and multiple oxide oreFloating agent of ore beneficiation and its preparation method and application.
Background technology
Mineral resources belong to disposable resource, have non-renewable, due to exploitation utilization for many years, in the world all kinds of ore depositsAbundant ore source reduces day by day, but due to industry, agricultural and the increase of other industry to disposable mineral resources demand, utilizes poorOre deposit and difficult ore dressing will be more and more important. The most ore resources of China generally have the feature of " poor, thin, assorted ", and 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 to closeCollecting agent and the floatation process thereof of reason are produced 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 the pig iron producesAmount 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 substantiallyIronmaking benefit, increases the benefit of associated industry. In addition, the impurity such as other mineral concentrate sulphur, phosphorus, arsenic are low, all have smeltingGenerally promote the effect of economic benefit, ore dressing can make ore dressing plant and the acquisition pair of smelting company with smelting by reasonable prices mechanismWin. 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 to domestic metallurgical mine enterpriseLarge pressure. China iron deposit stone resource is poor, particularly compares China with Australia with Brazil of iron ore leading exporterIron ore resource there is following obvious deficiency: 1. average head grade is lower; 2. the ratio of rich ore is on the low side; 3. SiO2ContentHigher; 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 givenMineral processing in China worker has higher requirement. Mineral processing in China worker must constantly strengthen upgrading and fall and assortedly (especially carry ironFall silicon, carry iron and fall phosphorus, carry iron and fall sulphur) and the research selected again of iron-containing tailing, the self-produced iron ore concentrate of Cai Nengshi China overcomes congenitalFoot, 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 at steel industry competing to strengthen selfStrive today of power, metallurgical mine enterprise application reverse floatation process strengthen to iron ore concentrate carry Fe and reducing Si, carry iron fall assorted (fall phosphorus,Fall sulphur, fall arsenic, spoil reclaming), this tool is of great significance.
At present, the technique that silicon falls in iron ore reverse flotation has two kinds: a kind of be the moon of growing up from high intensity magnetic mineral reverse flotation fromSub-reverse floatation process, this technique obtains more general application in China; Another kind is cation reverse flotation technique, industrial flourishing stateThe general cation reverse flotation technique that adopts of family. Although adopting anion reverse floatation technique can obtain good sorting, China refers toMark, but flotation temperature high (flotation of need heating), energy consumption is large, use pharmacy variety many (need 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 main at presentBe amine collector, comprise fatty amine and ether amine. Replaced quantity according to hydrogen in amine molecule by other alkyl (being mainly methyl)How much 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 binaryAmine. Amine collector development is slower, and it is compared with anion reverse floatation collecting agent, and amine collector separating effect also relativelyPoor, 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, it is de-to be conducive to filterWater.
In addition, along with iron ore and some special ore species resources reduce and country to environmental protection, resource reutilizationConstantly pay attention to, people start to pay attention to some originally discarded 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. reclaim iron and phosphorus, rare earth, tungsten,Research and development and the production application work of bismuth, molybdenum, titanium, fluorite etc. Therefore, innoxious, the energy-conservation environmental protection of beneficiation reagent withAnd multiple-effect, efficient, wholesomeness also seem particularly important. Strengthen to the research work of green non-poisonous, pollution-free, degradable medicament withAnd 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 outOre 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-conservation subtractingRow, energy-saving and cost-reducing there is for a person skilled in the art important theory significance and actual promotional value.
Summary of the invention
