Abstract
The invention discloses a process for extracting white carbon black in alkaline-leaching and vanadium extraction of stone coal, which aims at solving the problem that no mature process for extracting white carbon black from filter residues of the stone coal, which are subjected to sodium-free blank roasting, alkaline leaching and vanadium extraction, exists at present. The process comprises the following steps of: carrying out sodium-free blank roasting on the stone coal, adding 3-7% of industrial alkali, soaking for 3-5 hours at 65-95 DEG C, putting the obtained lixivium to a white carbon black reaction kettle, heating to 75-85 DEG C, simultaneously adding concentrated sulfuric acid to adjust the pH to 5-6, stirring and maintaining for 0.5-1.5 hours, carrying out conventional pressure filtration, simultaneously introducing hot water of 65-75 DEG C, conventionally pulping the obtained filter cake, carrying out spray drying to obtain the white carbon black, and carrying out vanadium extraction on the obtained filtrate and water washing liquid. The invention is used for extracting the white carbon black from the filter residues of the stone coal, which are subjected to sodium-free blank roasting, alkaline leaching and vanadium extraction, has the advantages of simple and convenient process, high extraction yield, good benefit and no environmental pollutant emission, and realizes the comprehensive development and cyclic utilization of the stone coal.
Description
Technical field
The present invention relates to a kind of technology of in alkaline-leaching and vanadium extraction of stone coal, extracting white carbon black.
Background technology
The main component of bone coal is a silicon-dioxide, belongs to many metals associated minerals, because its reserves are many, utilizes difficulty to be regarded as the utilize resources synthetically of enjoyment preferential tax revenue greatly by country.
The existing technology of extracting vanadium from bone coal is that technology is invaded in sodium roasting acid, and this technology exists extraction yield low, and the silicon-dioxide that the chlorine exhaust emission is arranged, accounts for bone coal 70% is as the industrial residue discharging and deficiencies such as contaminate environment; Bone coal does not have the sodium blank and fuses alkali to leach the vanadium extraction technology be a kind of innovative technology of the applicant at prior art, and it is low and have a deficiency such as chlorine pollution to have overcome the prior art extraction yield; Do not have in the blank roasting alkaline-leaching and vanadium extraction of the sodium technology at this bone coal, produced the filter thing that contains a large amount of silicon-dioxide equally, not from wherein extracting the maturation process of white carbon black,, can cause the waste of high added value silicon-dioxide in the prior art as directly these being filtered things as cement material utilization; And in line both the waste especially polluted environment.
Summary of the invention
Purpose of the present invention will overcome above-mentioned deficiency exactly, a kind of technology of extracting white carbon black in alkaline-leaching and vanadium extraction of stone coal is provided, this technology can be extracted white carbon black from the extract of the blank roasting alkaline-leaching and vanadium extraction of no sodium, its technology is easy, extraction yield is high, profitable, non-environmental-pollution has been realized bone coal comprehensive exploitation and recycle.
For achieving the above object, technical scheme of the present invention is that this extracts white carbon black in alkaline-leaching and vanadium extraction of stone coal technology comprises the steps:
A, in the roasting bone coal, adding mass ratio is the industrial soda of 3-7%, 65-95 ℃ was soaked 3-5 hour, conventional filtration gets leach liquor;
B, the leach liquor of step a gained is put into the white carbon black reactor be heated to 75-85 ℃, add the vitriol oil simultaneously and regulate ph to 5-6, stir and kept 0.5-1.5 hour;
C, with the conventional press filtration of the emulsion of step b gained, feed hot water washing leaching cake in pressure filter of 65-75 ℃ simultaneously.
D, the filtrate and the water lotion of step c gained carried out vanadium extraction, the conventional slurrying of gained filter cake, spraying drying, white carbon black.
The present invention does not have the blank roasting of sodium with bone coal, the industrial soda that adds 3-7%, 65-95 ℃ was soaked 3-5 hour, the gained leach liquor is put into the white carbon black reactor and is heated to 75-85 ℃, add the vitriol oil simultaneously and regulate ph to 5-6, stirring was kept 0.5-1.5 hour, conventional press filtration, feed 65-75 ℃ hot water simultaneously, the conventional slurrying of gained filter cake, spraying drying, get white carbon black, the filtrate of gained and water lotion carry out vanadium extraction, this is wherein recyclable to leach the vanadium more than 90% in the thing, make that the extraction yield of vanadium has improved 50% in the bone coal, and whenever carry one ton of vanadium and can extract white carbon black more than 6 tons, make the benefit of extracting vanadium from stone coal increase by 30%, one is the factory that raw material is produced 1500 tons of vanadium per year with high silica coal, can reduce the discharging of vanadium extraction extract every year more than 10000 tons, simultaneously, can form the precipitation level white carbon black of producing per year more than 10000 tons, turn waste into wealth, improve the comprehensive utilization benefit of bone coal resource greatly, reduced environmental pollution.This technology is easy, extraction yield is high, profitable, non-environmental-pollution has been realized the comprehensive exploitation and the recycle of high silica coal.
