Abstract
A process for directly preparing antimony white includes such steps as using organic adhesive to agglomerate the antimony-contained material, calcining the agglomerate in Weishi furnace, volatilizing antimonide, oxidizing fume, separating mechanical impurities, recovering coarse antimony oxide, and purifying by ion exchange water in ultrasonic stirring drum. The invention has the characteristics of wide raw material source, simple equipment, no environmental pollution, low cost and the like. The recovery rate of antimony is above 97%, the purity of the obtained antimony white can reach 99.5%, and the whiteness can reach 87%. The invention is suitable for processing antimony sulfide mineral powder, antimony oxide mineral powder, mixed antimony mineral powder and other antimony-containing materials with different grades.
Description
The present invention relates to a kind of organic binder bond that adopts carries out briquetting, roasting volatilization impurity, produces the method for high pure antimony white with water treatment antimong-containing material.
Stibium trioxide is the oxide compound of antimony, mainly is Sb
2O
3, the method for producing stibium trioxide at present mainly contains two kinds of wet method and pyrogenic processes.Pyrogenic process adopts indirect method more, and the pyrogenic process of domestic employing generally is raw material with the star metal, adopts the reverberatory furnace self-heating to produce high pure antimony white, and this method is to the ingredient requirement strictness, and technical process is long, and investment is big, the schedule of operation complexity; The external pyrogenic process that adopts has two kiln methods, and this method technical process is short, the plant factor height, but require low arsenic, low plumbous antimony mineral raw material, otherwise product purity is lower.Wet method is produced stibium trioxide, and requiring the higher-grade antimony ore is raw material, and possesses anticorrosion equipment, contaminate environment, and production cost is higher, and product whiteness is not good enough.
The method that the purpose of this invention is to provide a kind of production cost direct production stibium trioxide low, applied widely.
The present invention is raw material with the antimony-containing mineral, adopt the aqueous solution of humate to make binding agent, and add a certain amount of high-melting-point material (ground dolomite and pulverized anthracite), produce the antimony ore nodulizing, nodulizing is at continous way or intermittent type fixed bed Webster kiln roasting, volatilization stibnide, flue gas directly reclaims thick weisspiessglanz behind oxidation and separation machinery impurity, purifying with the ion exchanged water of heat at last just can obtain high pure antimony white.
Technical process of the present invention is as follows:
In antimony mineral, add 4～10% ground dolomite (granularity-200 order accounts for more than 80%) and 8% pulverized anthracite (granularity-200 order accounts for more than 80%), in order to prevent the fusion of nodulizing stibnide, add 1～1.5%(butt meter at last) the aqueous solution of humate make binding agent, be made into the nodulizing compound, after stirring with biaxial rneader then, make the fourth of the twelve Earthly Branches shape nodulizing of thick * wide * long=25 * 30 * 40 through mixing balling press, nodulizing gets the finished product nodulizing after 180～220 ℃ of dryings.Present method is adapted to antimony sulfide breeze, weisspiessglanz breeze, mixing antimony ore powder and other antimong-containing material of different grades.
With the fourth of the twelve Earthly Branches shape antimony ore nodulizing made at continous way or intermittent type fixed bed Webster kiln roasting volatilization stibnide, maturing temperature is 1000～1100 ℃, roasting time is 90～120 minutes, flue gas is through the oxidizing chamber oxidation greater than 1100 ℃ and suction air, behind settling pocket separation machinery impurity, cooling reclaim 99% thick weisspiessglanz.For purity and the whiteness that improves sb oxide, the air capacity that control enters oxidizing chamber makes oxidizing atmosphere excessive, satisfies the oxidation of S, Sb, and in dust collecting system, the cooling tube stainless steel tube is collected weisspiessglanz with the temperature resistant fiber cloth bag.With 99% the thick weisspiessglanz of collecting, make equipment for purifying with being with hyperacoustic agitation vat, with ion exchanged water as the purification solvent, its solid-liquid weight ratio is that 1: 6～8 temperature are 40～80 ℃, and the time is 100～120 minutes, through precipitation, filtration, the dry high pure antimony white that gets, its purity can reach 99, more than 5%,, adopt colloidal mill levigate in order to obtain the thinner stibium trioxide of granularity.
The present invention with existing method (pyrogenic process, wet method) relatively has following advantage: owing to use the humic acids salt to make binding agent, cohesiveness is strong, nodulizing intensity height, and humic acids salt wide material sources, and cost is low; Be added with high-melting-point ground dolomite and pulverized anthracite in the nodulizing, improve the nodulizing fusing point, avoid fusing, improved the metallurgical performance of nodulizing, prevent the fusion of low melting point stibnide, help improving the rate of recovery of antimony, the rate of recovery is more than 97%; With continous way or intermittent type fixed bed Webster kiln roasting, the purity that helps improving weisspiessglanz, whiteness and dispersity; Adopt the ion exchanged water of heat to make the purification solvent, cost is low, and equipment is simple, and is free from environmental pollution; The present invention is adapted to handle different content, dissimilar antimony ore and antimong-containing material, and tooling cost is lower more than 40% than pyrogenic process, and low antimony recovery is more than 97% more than 60% than wet method, and the purity of gained stibium trioxide can reach 99.5%, and whiteness can reach 87%.Embodiment: by weight percentage: antimony sulfide breeze 85.5%, pulverized anthracite 8%, ground dolomite 5%, humic acids salt about 1.5% (butt meter), behind the compound uniform mixing, make the fourth of the twelve Earthly Branches shape nodulizing of thick * wide * long=25 * 30 * 40, wet nodulizing got the finished product nodulizing after under 190 ℃ dry 30 minutes, with the fourth of the twelve Earthly Branches shape antimony ore nodulizing made at intermittent type fixed bed Webster kiln roasting, maturing temperature is 1050 ℃, time is 90～120 minutes, through oxidizing chamber is the antimony sulfide oxidation weisspiessglanz, behind settling pocket separation machinery impurity, with stainless steel tube cooling (surface sprinkling), in the temperature resistant fiber cloth bag, collect 99% thick weisspiessglanz, this weisspiessglanz in hyperacoustic agitation vat is housed with 80 ℃ ion exchanged water (solid-to-liquid ratio is 1: 8) as the purification solvent, extraction time is 110 minutes, through precipitation, filter, dry purity is the stibium trioxide more than 99.5%.
