Description
Technical field
The present invention relates to nickel sulfide ore recycling field, and in particular to one kind prepares nickel sulfate with nickel sulfide ore normal pressure
The method of ammonium.
Background technology
The handling process of nickel sulfide ore generally can be divided into pyrogenic process and wet method.Pyrogenic attack technique is to use matte smelting, will
Ni-B alloy in nickel sulfide ore is into low nickel matte, then by low nickel matte with bessemerizing into high nickel matte, then produces through different method of refining
Go out different nickel products.Main technique has nickel sulfide ore shaft smelting, electro-smelting, flash smelting and bath smelting etc..
Wet processing process, which generally refers to leach into solution, puies forward nickel process, and main technique has sulfating roasting lixiviation process, normal pressure
Ammonia leaching process, pressure ammonia leaching method, oxygen leaching method and chlorination leaching process etc..
The chemical formula of ammonium jarosite is：NH4Fe3(SO4)2(OH)6, in the sulphuric leachate of iron content, form ammonium jarosite
Precipitation, the iron in solution can be removed, equation is simplified as：
3Fe3++NH4 ++2SO4 2+6H2O→NH4Fe3(SO4)2(OH)6↓+6H+ (1)
The characteristics of this method is：Ammonium jarosite crystal is easily formed, and leachate is easily clarified, filters and separated, metal
(Ni, Cu, Mn) loss is low.
Normal pressure leaching is usually the technique carried out below room temperature or solution boiling temperature, and often leaching velocity is slower, leaching
The time gone out is longer.
By nickel sulfide ore grinding into small particle, the contact area of nickel sulfide ore and liquid can be increased, increase reaction rate.
The content of the invention
To solve the problems, such as that prior art is present, ammonium nickel sulfate is prepared with nickel sulfide ore normal pressure the invention provides a kind of
Method.This method has the characteristics of technological process is short, cost is low, green.
To achieve the above objectives, this invention takes following technical scheme：
A kind of method that ammonium nickel sulfate is prepared with nickel sulfide ore normal pressure, comprises the steps：
(1) raw material leaches
In parts by weight, in 100 parts of nickel sulfide ore, 200-500 parts diluted acid, 40-60 parts oxidant and 5- are added
10 parts of sulfuric acid calcium inhibitorses, after being well mixed, at 60-90 DEG C, 1-6h is reacted, obtains nickel sulfate leachate；
(2) leachate cleans
In leachate, ammoniacal liquor and lime stone are added, by ferriammonium sulfate method iron removaling, it is 2 to react to solution ph；Iron removaling
Leachate afterwards adds ammoniacal liquor, and it is 11 to react to solution ph, obtains ammonium nickel sulfate solution and contamination precipitation.
Oxidant is copper sulphate, hydrogen peroxide, Peracetic acid, potassium permanganate or ammonium persulfate.
Sulfuric acid calcium inhibitors is polyethylene diacid, polyacrylic acid or citric acid.
In step (1), the fineness of nickel sulfide ore is 10 μm, is milled using steam kinetic energy..
In step (1), diluted acid is sulfuric acid, hydrochloric acid or nitric acid, and the concentration of diluted acid is 10%.
Relative to prior art, the present invention have it is following a little：
The present invention adds diluted acid, oxidant, sulfuric acid calcium inhibitors, after being well mixed, reaction, obtained in nickel sulfide ore
Nickel sulfate leachate.In leachate, ammoniacal liquor and lime stone are added, passes through ferriammonium sulfate method iron removaling；Leachate after iron removaling adds
Enter ammoniacal liquor and obtain ammonium nickel sulfate solution and contamination precipitation.The present invention has the characteristics of technological process is short, cost is low, green.
This method is the nickel sulfide ore come out using mine direct flotation, after grinding, method that normal pressure leaching prepares ammonium nickel sulfate.
Wherein, oxidant can promote nickel sulfide ore dissolving with vulcanizing nickel reactant.The calcium impurities contained in nickel sulfide ore, easily generate sulfuric acid
Calcium precipitate causes fouling and line clogging in reactor wall or pipeline, and crystal of calcium sulfate can be avoided by adding sulfuric acid calcium inhibitors
Precipitation.With ferriammonium sulfate method sink iron when, add lime stone and neutralize and unnecessary acid, advantageously reduce cost.Again after iron removaling
Solution in add ammoniacal liquor, other magazines in solution are precipitated in the form of hydroxide, and nickel is stayed in the form of ammonium nickel sulfate
In solution.The present invention has the characteristics of technological process is short, cost is low, green.
Further, the grinding mill used grinds for vapor stream, and the grinding machine has the spy that mill efficiency is high, diameter of particle is thin
Point.
