Description
Technical field
The present invention relates to cobalt copper sulfide ores to roast field, and in particular to a kind of new work of sulfating roasting cobalt copper sulfide ore
Skill.
Background technology
In cobalt metallurgy of copper, thermal process maturation, stable operation, but invest greatly, generally use matte smelting-blowing work
Skill, there are SO2Smoke problem.Wet process is eliminating SO2Damage by fume and expansion copper resource utilization scope etc. have centainly excellent
More property, therefore be increasingly taken seriously.Domestic and international wet method refining cobalt process for copper has been successfully used to processing cobalt oxide copper concentrate, barren rock
Heap, but for cobalt copper sulfide ore, in addition to roasting leaching and ammonia leaching flow are industrially applied, other flow many places in
Conceptual phase.About extremely intractable cobalt copper sulfide ore in hydrometallurgy in acid FeC13With acid Fe2(SO4)3It is molten in solution
It is a lot of to soak dynamic (dynamical) report, but as the commercial run of processing sulphide ore, the disadvantage is that long flow path, a large amount of iron enter solution,
Except iron or regeneration FeC13Difficulty, effect are poor.Traditional hydrolysis selective precipitation method is generally used, iron is with sulphur with hydroxide colloid
Form exists, it is difficult to filter, and colloid copper ion containing mother liquor is more, not uncomplicated laundering.Colloid is set to be aggregated though flocculant can be used,
Industrially extensive use is difficult to because of high cost.Even use microwave leaching cobalt copper mine effect also undesirable, though soaking
Suitable oxidant MnO is added during going out2, use H2SO4Solution leaches, and avoids Fe in leaching solution (OH)3·nH2O colloids
It generates, but molten leaching number up to 7 times or more, therefore, practical problem will also be become by industrially applying.
Invention content
The purpose of the invention is to overcome above-mentioned technical problem, a kind of new work of sulfating roasting cobalt copper sulfide ore is provided
Skill makes copper cobalt be converted into water-soluble CuSO as possible4、CoSO4, while iron being made to be converted into the oxidation insoluble in dilute sulfuric acid as possible
Object, finished product calcining material copper cobalt water logging leaching rate >=96%.
The technical problem of the present invention is mainly addressed by following technical proposals：
A kind of new process of sulfating roasting cobalt copper sulfide ore, comprises the following steps that：
A kind of new process of sulfating roasting cobalt copper sulfide ore, cobalt copper sulfide ore is through crusher, reciprocating sieve, bucket lifting
Machine, furnace top bin, sulfating roaster, drum-type water cooling, obtain finished product calcining material, and the sulfating roaster is blown by roots blower
Into stove, the sulfating roaster contains SO2Flue dust enters sulfate system relieving haperacidity, the rotation through rotoclone collector, cottrell successively
Through helical conveyer to aforementioned drum-type water cooling stage, the drum-type water cooling stage is set for wind dust-precipitator, cottrell institute's smoke abatement
There is overflow port that calcining is discharged.
Specifically, the cobalt copper sulfide ore is delivered to crusher through belt, then reciprocating sieve is delivered to through belt.
Specifically, the bucket elevator feeds into furnace top bin through electronics batcher.
Specifically, disposing heat exchanger tube when the roasting kiln roasting in stove, 640 DEG C ± 50 DEG C of acidizing fired temperature is kept.
Specifically, the cobalt copper sulfide ore is through crusher in crushing, after reciprocating sieve, granularity ＜ 10mm.
The purpose of sulfating roasting of the present invention is that copper cobalt is made to be converted into water-soluble CuSO as possible4、CoSO4, while making iron
It is converted into the oxide insoluble in dilute sulfuric acid, such as Fe as possible2O3、Fe3O4, in order to handle in next step.Process conditions and main anti-
It should be as follows：
Temperature：640℃±50℃
Furnace pressure：2100-2400mm water columns
Exiting flue gas oxygen concentration 3-8%
Material was in residing time in furnace 1-60 minutes
CuFeS2+4O2=CuS04+FeS04
3CuFeS2+10O2=3CuSO4+Fe3O2+3SO2
3Fe2(SO4)3=2Fe3O2+6SO2+1002
SO3=SO2+0.5O2
CuCo2S4+702=CuSO4+2CoSO4+SO2
CoS+2O2=CoSO4
CoO+SO3=CoSO4
When being acidified stove normal work, furnace pressure need to be stablized, general warranty furnace pressure goes out in 2100-2400mm water columns
Mouthful oxygen concentration of flue gas 3-8% controls each portion's temperature in stove and stablizes, according to 640 DEG C of sulfating roasting effect fluidized layer temperature temperature
± 50 DEG C, and throw the speed of mine amount and in-furnace temperature to have close relationship, feeding quantity be an important control parameter, it is determined
Fluidized layer temperature and the blow rate required and flue-gas temperature, any variation of feeding quantity can all cause the control of main operating parameters
The variation of index.It is acidified stove control feeding coal and uses electronics batcher, by adjusting FREQUENCY CONTROL delivery rate, ensure that feed is equal
It is even, control feed weight.
A kind of new process of sulfating roasting cobalt copper sulfide ore provided by the invention, the acidizing fired condition of solution acidification stove,
Cobalt copper sulfide ore contains SO into stove granularity, control2Smoke harm, so that it is guaranteed that finished product calcining quality and calcining material copper cobalt leaching rate >=
96%.
