To achieve the above object, the technical solution adopted by the present invention comprises the concrete steps that：
Impregnate 1 ~ 3 hour, be separated by filtration Step 1: the copper ashes that granularity is 1 ~ 2mm is placed in boiling water, then 110 ~ 8 ~ 10 hours dry under the conditions of 120 DEG C, the aperture of sieving, the sieve is 1mm, takes oversize, obtains copper ashes particulate material.
Step 2: the copper ashes particulate material is placed in Muffle furnace, calcines 1 ~ 3 hour, obtain under the conditions of 700 ~ 850 DEG C Calcine copper ashes particle.
Step 3: being 1 ︰ (3 ~ 5) by the mass ratio of hydrochloric acid solution described in calcining copper solid impurity particle ︰, to the calcining copper ashes The hydrochloric acid solution of a concentration of 0.5 ~ 1mol/L is added in grain, stirs 10 ~ 15 minutes, then washes and filters 3 ~ 4 times successively, before being made Drive body copper ashes particle.
Step 4: the water for accounting for 10 ~ 15wt% of the presoma copper ashes particle is added in the presoma copper ashes particle, it is wet Granularity≤60 μm are milled to, wet-milling copper ashes powder is made.
Step 5: being 1 ︰ (0.05 ~ 0.1) by the mass ratio of wet-milling copper ashes Fen Mo ︰ coke blackings, by the wet-milling copper ashes powder It is added in pug mill with the coke blacking, vacuum squeezes mud molding, ageing mixture 24 ~ 36 hours；Be placed in again in resistance furnace and be warming up to 1100 ~ 1150 DEG C, 1 ~ 3 hour is kept the temperature, furnace cooling is made using copper ashes as the fe olivine material of major ingredient.
The copper ashes is the clinker of generation during copper metallurgy；The main chemical compositions of the copper ashes are：SiO2For 35 ~ 40wt%, Fe2O3It is 6 ~ 10wt% for 35 ~ 40wt%, CaO, MgO is 1 ~ 5wt%, Al2O3For 2 ~ 4wt%.
The hydrochloric acid is that analysis is pure.
C content >=95wt% of the coke blacking.
The vacuum squeezes the molding vacuum degree≤0.05Pa of mud.
Due to the adoption of the above technical scheme, the present invention has following good effect compared with prior art：
1, the present invention uses copper ashes for primary raw material, both makes full use of resource, realizes returning for nonferrous smelting waste material It receives and utilizes, and reduce the manufacturing cost of fe olivine material.
2, copper ashes is burnt by the present invention after series of processes, simple for process, is not necessarily to special equipment and treatment technology, energy Consume small and saving human resources.
3, the present invention utilizes the physicochemical characteristics and reaction in-situ of raw material components, improves the conversion ratio of fayalite, It enhances using copper ashes as the sintering character of the fe olivine material of major ingredient.
The present invention prepare using copper ashes as the fe olivine material of major ingredient after testing：Bulk density is 3.38 ~ 3.43g/ cm3；Fayalite conversion ratio is 75 ~ 80%.
Therefore, present invention process is simple, energy consumption is small, production cost is low and to equipment without particular/special requirement；It is prepared with copper Slag be the fe olivine material of major ingredient sintering character is good and fayalite high conversion rate.
