Description
Technical field
The present invention relates to a kind of additive for taking off lead dephosphorization for strengthening high lead high phosphorus promoter manganese, in particular to one kind passes through
Addition is roasted by the additive that iron compound, calc-flux and sodium salt form to strengthen high lead high phosphorus promoter manganese, is roasted by regulation
Burning-magnetic separation process realizes method that de- lead dephosphorization obtains jakobsite material, belongs to mineral processing, metallurgical engineering and material
Preparation field.
Background technique
Manganese is a kind of important strategic resource, and 90% manganese disappears as the deoxidier and desulfurizing agent and alloying element of molten steel
It consumes in steel industry, 10% is used for other relevant industries.It is 64351.7 ten thousand t, reserves that China's manganese ore, which adds up proved reserves,
592040000 t are mainly distributed on the provinces and regions such as Guangxi, Hunan, Guizhou, Sichuan, Liaoning, Yunnan, Zhan Quanguo manganese resource gross reserves
90%.
Currently, the especially development of steel industry, the demand of manganese ore is got in market with economy and industrial expansion
Come bigger.The notch between the consumption and Ore Yield of Chinese manganese ore increases year by year as a result, and China relies on import within 2014
Manganese ore amount be up to 6,470,000 t.The main reason for leading to this situation is that China's manganese ore grade is low, the high-quality rich manganese ore of high-grade
Resource is almost without the manganese ore 100% for producing medium-low carbon ferromanganese depends on import.Resource it is poor, miscellaneous, thin the features such as constrain
The efficient utilization of manganese ore.The average grade of China's manganese ore generally contains higher Si, Fe, P, Pb, wherein P 20% or so
The exceeded manganese ore of content accounts for 49.6%.In addition, ferrimanganic polymetallic ore resource often altogether, associated silver, lead, zinc, cobalt etc., manganese average grade
Only 15%, reserves account for 19%.
Low-grade iron ore could be used for Mn series alloy smelting after must carrying out ore dressing.The ore dressing of manganese ore has gravity treatment, Qiang Ci
The techniques such as choosing, again-magnetic separation, strong magnetic-flotation can remove some gangue minerals by ore dressing, improve manganese grade.But China's manganese
Ore structures are complicated, and disseminated grain size is thin, and valuable mineral is combined closely with gangue, selects smelting difficulty larger, for iron, manganese mineral and has
The evil simple Ferromanganese Ore of the embedding cloth of element, the separation of ferrous manganese ore object and gangue may be implemented using conventional beneficiation method.But by
The close symbiosis of ferrimanganic in China's ferrimanganic ore resources, disseminated grain size is thin, and lead, phosphorus etc. smelt harmful element mostly with lattice substitution, class
Matter with elephant form preservation in iron, manganese mineral, be only having for difficult to realize manganese iron and harmful element by routine ore-dressing technique
Effect separation.Although Mn-rich slag method can effectively remove the harmful elements such as lead, phosphorus, Mn-rich slag method smelting temperature is high, needs to disappear
A large amount of fuel and reducing agent are consumed, a large amount of solid, gas pollutant is generated.
Manganese anode slime is also the manganese resource of a kind of high lead-type.In electrolytic manganese production process, oxygen is precipitated in anode, and have
A small amount of earth of positive pole deposition.This earth of positive pole is dark brown color substance, is a small amount of Mn in electrolytic process2+In the MnO that anode discharge generates2
The product deposited on anode plate.The earth of positive pole that 1 ton of electrolytic manganese of every production can generate the high rate containing manganese is 0.05~0.08 ton, in recent years
To come, China's electrolytic manganese metal yield maintains 1,200,000 tons or so, and it is therefore, annual to generate electrolysis anode sludge 6~9.6 ten thousand ton or so,
Cumulant has reached 920,000 tons or more.These earth of positive pole are because of its complicated composition, it is difficult to be used, generally as dangerous debris dump
It deposits, steel-making additive or undersell, is not preferably developed and comprehensively utilized, not only the wasting of resources, but also handle not
When easily causing considerable degree of environmental pollution.
In addition, ferrimanganic base spinel type ferrite purposes is very wide, wide in variety, quantity is big, a kind of high ferrite of the output value
Material.Soft magnetic materials is mainly used as various inductance elements, such as filter magnetic core, magnetic core of transformer, radio magnetic core and tape
The critical material of recording and video recording head etc. and magnetic recording element.Hard magnetic material is mainly used for the phonographic recorder in telecommunications devices,
Sound pick-up, loudspeaker, the magnetic core etc. of various instrument.
The method for preparing such material at present is to use to analyze pure or high-purity mineral dust using high temperature solid phase synthesis
Mode through multistage roasting ore grinding directlys adopt low-grade manganese ore and prepares jakobsite material and be rarely reported to prepare.It passes
System solid reaction process prepares jakobsite material as raw material to analyze pure, ultrahigh quality mineral.But preparation analysis is pure and mild
Process flow that the separating-purifying of mineral needs to grow very much, a large amount of chemical reagent of consumption, lead at high cost, low efficiency.
