Abstract
A kind of method that ceramic material is prepared using copper tailing, belongs to Industrial Solid Waste comprehensive utilization of resources and field of environment protection.After the raw materials ball milling mixings such as 35~55 parts of copper tailing, 25~40 parts of slag, 10~25 parts of clay, 0~15 part of feldspar, 0~10 part of talcum, through being sieved, drying, suppressing or the processes such as extrusion forming, sintering obtain ceramic material, firing temperature is 1080 DEG C~1160 DEG C.Using copper tailing collaboration prepared from steel slag for ceramic material in the present invention, Industrial Solid Waste dosage accounts for total weight ratio up to 65%~85%, it can be achieved that the extensive recycling of Industrial Solid Waste, has apparent social benefit, environmental benefit in ceramic raw material.Copper tailing used and slag raw material particle size are thinner, can reduce ceramic material production process ball milling energy consumption, and firing temperature is relatively low, can reduce ceramic material firing energy consumption, have economic benefit.Present invention process is relatively easy, easily promotes and applies.
Description
Technical field：
The present invention relates to a kind of methods that ceramic material is prepared using copper tailing, belong to Industrial Solid Waste comprehensive utilization of resources
And field of environment protection.
Background technology：
China's industry ore dressing and the yield of solid waste in smelting process are continuously increased, but China's industrial tailings at present
Not high with the level of comprehensive utilization of metallurgical slag, the burden for leading to China's tailing and metallurgical slag is huge.Although mine and smelting are looked forward to
Industry constantly strengthens technological development, and it is still rationally current important using the effective way of Industrial Solid Waste to explore extensive recycling
Business.
By the use of Industrial Solid Waste as ceramic industry raw material be scale utilize Industrial Solid Waste an important channel.Copper tailing
It is the solid waste that copper manufacturing enterprise discharges after the techniques such as flotation or leaching choose copper resource, contains a large amount of silicate mine
Object, can be as the primary raw material for preparing ceramic material.At present, " secondary " tailing that copper tailing generates after selecting again still mainly with
Stockpiling mode is handled, and ceramic material is prepared using copper tailing, can not only mitigate the burden of copper manufacturing enterprise processing tailing, but also can be with
Expand ceramic raw material source.Patent publication No. CN102924113A, CN103030341A and patent announcement CN100591635C,
CN102674883B proposes the method that porous ceramics or glass material are prepared using copper tailing, these methods are used to utilize copper
Tailing prepares porous material, all has feasibility in technique, but preparation process has used pore former so that in production process
Control difficulty it is larger, therefore be unfavorable for Technique Popularizing application.There has been no utilize the standby ceramic material of copper tailing collaboration prepared from steel slag at present
The report of material.
Invention content：
Method of the prepared from steel slag for ceramic material is cooperateed with using copper tailing the object of the present invention is to provide a kind of, realizes copper tailing
With the comprehensive utilization of resources of slag, this method has apparent society, economy and environmental benefit.
The specific technical solution of the present invention includes the following steps：Raw material copper tailing, slag, clay, feldspar, talcum are weighed,
Each raw materials by weight portion forms：35~55 parts of copper tailing, 25~40 parts of slag, 10~25 parts of clay, 0~15 part of feldspar,
0~10 part of talcum.Then binder 0.01%~0.1% is added in mixture, dispersant 0.05%~0.3% will mix
Material plus water polo are milled to 250 mesh and tail over less than 0.8%.After slurry is dried, pass through compression moulding or extrusion forming.It finally will be into
Green body after type is sent into kiln and is fired at 1080 DEG C~1160 DEG C, obtain using copper tailing, slag as primary raw material ceramics
Material.
The present invention has the following advantages：
(1) using copper tailing collaboration prepared from steel slag for ceramic material, Industrial Solid Waste dosage accounts for total weight ratio in ceramic raw material
Up to 65%~85%, it can be achieved that the extensive recycling of Industrial Solid Waste, has apparent social benefit, environmental benefit.
(2) copper tailing used in and slag raw material particle size are thinner, can reduce ceramic material production process ball milling energy consumption, and burn
Temperature processed is relatively low, can reduce ceramic material firing energy consumption, have certain economic benefit.
