Description
One, technical field
The present invention relates to the extraction of sulphur concentrate, specifically is a kind of method of extracting simple substance finished sulfur granule from the sulphur concentrate.
Two, background technology
At present, the main method of handling the sulphur concentrate both at home and abroad is to place stoving oven to carry out roasting in the sulphur concentrate, the SO of output high density
2Flue gas and burning slag, SO
2Flue gas adopts condensation technology SO through behind the washing, purifying
2Flue gas is made liquid SO
2Or make sulfuric acid, and the burning slag that contains valuable metal and rare precious metal takes the mode of hydrometallurgy to carry out the extraction of valuable metal and rare precious metal, and this method needs newly-built sulphur concentrate roasting workshop, gas cleaning, SO
2Liquefaction workshop or acid accumulator plant exist in implementation process that the facility floor space is big, investment cost is high, easily produce the low shortcoming of extraction yield of secondary pollution, valuable metal and rare precious metal.
Three, technology contents
The facility floor space that exists in the prior art is big, investment cost is high in order to overcome, easily produce the low deficiency of extraction yield of secondary pollution, valuable metal and rare precious metal, and the present invention proposes a kind of method of extracting simple substance finished sulfur granule from the sulphur concentrate.
Technical characterictic of the present invention is, the method for employing gravity separation and solid membrane sepn is carried out coarse filtration and smart purification processes of filtering to liquid-solid suspension, to improve the finished product sulphur quality of output.Leaching process of the present invention is:
The first step, drying, the sulphur concentrate with moisture 15%～30% adopts ordinary method to be dried to moisture 2%～7% sulphur concentrate, mass percentage content 〉=70% of elemental sulfur in the dried sulphur concentrate;
Second step, molten sulphur, utilize the method for steam indirect heat exchange in sulfur melting kettle, the sulphur concentrate to be carried out the successive molten processing, in 136-145 ℃ of temperature range, contained elemental sulfur is melt into the sulphur of liquid in the sulphur concentrate, sulphur liquid that the effect of the stirring transmission mechanism by sulfur melting kettle forms fusion and the solid particulate in the sulphur concentrate stir into liquid-solid suspension, reach the abundant fused purpose of elemental sulfur, the liquid-solid suspension that forms in the sulfur melting kettle flows automatically to the gravity separation still under the effect of high potential difference H=800-1000mm.
The 3rd step, gravity separation, the liquid-solid suspension that flows automatically in the gravity separation still does not carry out liquid-solid initial gross separation because the proportion of liquid-solid phase does not coexist under the immobilized state, and the clear liquor of sulfur-bearing is formed at the top in the gravity separation still.
The 4th step, Gu membrane sepn, separating the clear liquor of back generation uses the sulphur pump delivery in solid membrane separation apparatus, the mode that employing vacuumizes forms-0.05MPa～-pressure difference of 0.1MPa, under action of pressure, carry out the separation of solid-liquid, the purpose of reach smart filter, purifying is extracted into the sulphur liquid that contains elemental sulfur 〉=99% and flows automatically in the liquid sulfur pit;
The 5th step, granulate, with the sulphur pump sulphur liquid is transported to the sulphur nodulizer and granulates.
Because the purification processes that the present invention has taked the processing method of gravity separation and solid membrane sepn liquid-solid suspension to be carried out coarse filtration, smart filter, the finished product sulphur quality height of output, the present invention has taked the technical scheme of general-purpose equipment and common process, technology is simple, make from the sulphur concentrate rationally advanced to the technical process of extracting sulfur granule, the explained hereafter route is smooth and easy, equipment room is apart from compactness, is particularly suitable for directly leaching from zinc, lead ore concentrate the extraction of the simple substance finished sulfur granule in the sulphur concentrate that anode produced the sulphur concentrate that produced, the electrolytic copper technological process.
Four, description of drawings
Accompanying drawing 1 is the process flow sheet that extracts simple substance finished sulfur granule method from the sulphur concentrate.
Five, embodiment
