Description
Technical field
The present invention relates to ore dressing engineering and rare precious metal comprehensive utilization technique field, particularly a kind of efficient activator that is used for marmatite and zincblende flotation and its production and use.
Background technology
China's zinc metal reserves account for 15% of world's gross reserves, occupy the second in the world, and China also is a zinc big producing country simultaneously, and zinc metal output reached 374.9 ten thousand tons in 2007, ranked first in the world, and export volume reaches 27.56 ten thousand tons.Along with development and national economy, increase to zinc metal demand, press for the resource of complicated difficult choosing is developed and utilized, it is more domestic that leaded, zinc, sulphur, iron or zinc, copper, tin, iron, the plumbous zinc ore mountain of sulphur and zinc-tin mine etc. are in various degree the marmatite that contains choosing in distress all, for example, the big factory in Guangxi, river three plumbous zinc ores, the yellow sand level ground in Hunan, Pan Jiachong, the plumbous zinc ore of HERBA ONYCHII, the plumbous zinc ore in the Hezhang in Guizhou, the plumbous zinc ore in the tin iron mountain in Qinghai, the plumbous zinc ore in the XiLin in Heilungkiang, the ditch of grazing cattle in Jilin, so ox is washed in a pan plumbous zinc ore, the plumbous zinc ore of thick mother-in-law's col in Guangdong, all Long Xinxikuang in Yunnan and billows deep blue lead ore etc.The marmatite iron content in these mines is generally 8-12%, have up to 26%, therefore, adopt suitable marmatite ore-dressing technique, marmatite is developed and utilized significant.
Zincblende, marmatite and wurtzite are three kinds of common zinc sulfide minerals.Zincblende (ZnS) belongs to isometric system, and crystalline form often is a tetrahedron; Natural cleiophane contains zinc 67.1%, 32.9% sulphur.Wurtzite is general similar to the physical property of zincblende, generally rare in practice.The zincblende of iron content more than 6% is called marmatite [(Zn
XFe
1-XS)], zinc blend lattice is often sneaked into isomorph by Tie Tong, and the quantity of infiltrating iron is generally 6~12% (Gao Shida 26%).
In actual process, marmatite than zincblende show not easily-activated, floatability is poor, to characteristics such as medium sensitivities, it is difficult to separate with mineral such as magnetic iron ore, pyrite and mispickel.Simultaneously, compare with other sulfide mineral, the floatability of marmatite or zincblende is far smaller than other sulfide minerals, the general not activated marmatite or the flotation of zincblende need need the above xanthate of 4 carbon with hybrid collector or chain length, make the flotation of the zincblende comparison difficulty that seems.Therefore, activation is the important step in the marmatite ore dressing.Main in producing at present with the activator of copper sulphate as marmatite, however copper sulphate has following defective as activator:
(1) select marmatite for difficulty, the activation of copper sulphate is unsatisfactory, does not reach good index.
(2) activity function of copper sulphate strengthens along with the enhancing of alkalescence, therefore, the activation of copper sulphate generally is to carry out under a high-alkali environment, thereby certainly will need to add a large amount of lime aborning, so just suppress the flotation of the relatively poor zincblende of floatability, marmatite and oxidized mineral such as chalcopyrite.
(3) rolling up of lime consumption not only increases beneficiation cost, increases workman's workload, and from ore dressing and comprehensive the recovery and the angle of utilizing, the lime of big consumption also is worthless.In selecting the zinc process, adjust the pH value and suppress after other sulfide minerals with a large amount of lime, during next step flotation must come with a large amount of sulfuric acid and the lime in the ore pulp, to reduce the pH value, perhaps add a large amount of activator activation and other sulfide minerals of flotation, this has not only further increased beneficiation cost, and the calcium sulfate that lime and sulfuric acid reaction generate is easy to blocking pipe, at the gravitational separation equipment surface scale, seriously influences the continuity of mineral processing circuit and the rate of recovery of gravity treatment; In addition, sulfuric acid also can produce etching problem to pipeline and preparation equipment.
(4) copper sulphate and combination activator thereof also can activate difficult floating magnetic iron ore in the activation marmatite, increase the iron content in the zinc concentrate, to follow-up hydrometallurgy process, zinc and indium further separated with enrichment very unfavorable.In order to suppress magnetic iron ore, the often possible and large usage quantity of the kind of inhibitor, flow process are also complicated more.If the activator that is adopted is under low alkali condition, do not activate magnetic iron ore or pyrite and only activate marmatite and zincblende, then can simplify the deironing sulfur removal technology, save production cost, improve the grade and the rate of recovery of zinc concentrate zinc, indium, silver etc., reduce the content of iron and sulphur in the zinc concentrate, reduce the adverse effect of element such as iron in the zinc concentrate follow-up metallurgical process; Simultaneously, can also improve the rate of recovery of reselection operation significantly.
As seen, there are a lot of defectives in conventional activator of the at present domestic and international marmatite that adopts and inhibitor, and its activation is not high with the efficient and the selectivity that suppress, causes the rate of recovery of zinc and zinc concentrate grade not high, and metal contains seriously mutually.
Summary of the invention
