Abstract
The invention relates to a composite material of a binder and a preparation method thereof, and particularly relates to a using method of a granulation binder for chloride-leaching incineration residue. The using method comprises the following steps of: a preparing a binder; b bonding the chloride-leaching incineration residue; and c pelletizing, then firing to recover nickel-copper noble metal after pelletizing. The chloride-leaching incineration residue is bonded by using the binder, wherein the binder is prepared from sodium hydroxide or calcium hydroxide solution, and starch or modified cellulose solution. Thus, the using method is low in cost and convenient to popularize and use. Continuous agitation is needed when the chloride-leaching incineration residue is bonded by the binder; local agglomeration of the chloride-leaching incineration residue is prevented; the chloride-leaching incineration residue is clustered and hardened after being pelletized in a ball press machine, and then put into an alloy vulcanizing furnace to fire; no simple substance sulfur is separated out; and no splicing and agglomeration phenomena of the simple substance sulfur are generated in a secondary combustion chamber, a flue and an induced draft fan. In addition, the binder is used for carrying out pretreatment on the chloride-leaching incineration residue, thus, the recovery rate of the noble metal can be greatly increased; and the yield of the nickel-copper noble metal is also increased to over 90%.
Description
Technical field
The present invention relates to binding agent matrix material and compound method thereof, particularly a kind of chlorine soaks the using method of burning slag granulation binding agent.
Background technology
The copper ashes that produces in the metallurgy industry production process reclaims ambrose alloy wherein after chlorine leaches, the chlorine of generation soaks slag through reclaiming most of sulphur wherein behind the rotary kiln baking, and the chlorine that obtains soaks fired slags and is rich in a large amount of precious metals.When processing chlorine soaks desulfurization slag, because this material water ratio is lower, material is comparatively dry, in batching with when reinforced, chlorine soaks the desulfurization slag scene, and to fly upward phenomenon serious, cause the pollution of site environment and a large amount of losses of valuable metal, and it is higher that chlorine soaks in the desulfurization slag sulfur-bearing, part sulphur moment gasification in the reaction process, enter follow-up equipment with flue gas, gaseous sulfur is separated out with the reduction of flue-gas temperature, is bonded in secondary combustion chamber, flue and the induced-draft fan, cause corrosion and the obstruction of installations and facilities, and the hard cleaning that is difficult to of luming.Have a strong impact on the recovery of ambrose alloy precious metal, expend the plenty of time and the rate of recovery is low.
Summary of the invention
The object of the present invention is to provide a kind of suitability chlorine strong, with low cost, easy to use to soak the using method of burning slag granulation binding agent.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of chlorine soaks the using method of burning slag granulation binding agent, and concrete steps are as follows:
A, adhesive preparation
Binding agent is by sodium hydroxide or aqua calcis and starch or modified-cellulose solution composition, sodium hydroxide or calcium hydroxide and water are mixed and made into the aqueous solution, the mass concentration of sodium hydroxide or calcium hydroxide is 1-5%, starch or modified-cellulose and water are mixed and made into the aqueous solution, the mass concentration of starch or modified-cellulose is 1-10%, above-mentioned two kinds of solution is mixed and stirs make binding agent;
B, chlorine soak and burn the slag bonding
Binding agent is slowly added chlorine soak in the burning slag, add fashionable continuous stirring chlorine and soak the burning slag, the two is mixed;
C, granulation
Said mixture is put into the ball press pressurization granulates.
Described in the step a in the binding agent sodium hydroxide concentration be 2-4%.
Described in the step a in the binding agent mass concentration of starch or modified-cellulose be 4-5%.
To soak the blending ratio of burning slag be that per 100 gram chlorine soak to burn and add above-mentioned binding agent 35-45 milliliter in the slag for binding agent and chlorine among the step b.
A kind of chlorine provided by the invention soaks the using method of burning slag granulation binding agent, uses binding agent that chlorine is soaked the burning slag and bonds, and binding agent is by sodium hydroxide or aqua calcis and starch or modified-cellulose solution composition, and with low cost being convenient to promoted the use of.Binding agent soaks to burn to chlorine to be needed constantly to stir when slag bonds, and prevents that chlorine from soaking the local caking of burning slag.Go into ball press granulation back chlorine and soak the agglomerating sclerosis of burning slag, again chlorine is soaked and burn slag and go into the alloy vulcanizing oven and fire, change material phase in the roasting process, curing time, blowing process all act normally, flameholding does not have quick-fried ball phenomenon, and do not have elemental sulfur and separate out, all do not have bonding, the caking phenomenon of elemental sulfur in secondary combustion chamber, flue and the induced-draft fan.Use binding agent that chlorine is soaked the burning slag in addition and carry out pre-treatment, can improve the precious metal rate of recovery greatly, the ambrose alloy precious metal rate of recovery all is increased to more than 90%.
