Description
Technical field
Non-autoclaved and unburned manganese slag is prepared the present invention relates to industrial residue field of comprehensive utilization, in particular with manganese ore acid-soaked waste residue
The method of brick.
Background technology
China's promoter manganese rich reserves, are concentrated mainly on the manganese product yield of the southern areas such as Guangxi, Guizhou, wherein Guangxi
Rank first in the whole country position.Manganese product is fast-developing also to bring a series of problems to environment at the same time, is mainly manifested in manganese ore acidleach and gives up
The discharge capacity problem of the solid waste such as slag is on the rise.And, produce 1 ton of electrolytic manganese metal and discharge according to relevant enterprise statistics
About 8~9 tons of waste residue, produce about 5~6 tons of the waste residue of 1 ton of electrolytic manganese dioxide discharge, produce the manganese ore of 1 ton of manganese sulfate discharge
About 4 tons of acid-soaked waste residue.Nowadays various manganese waste slag cumulants are up to 6,000,000,000 tons in China.The problem of being handled due to manganese waste slag is increasingly tight
High, at present, many enterprises take the outdoor processing mode concentrated and stacked, and make every effort to reduce influence of the manganese waste slag to environment.It is but this
The elements such as Mn, Cr that stacking mode is but be easy to cause in manganese waste slag are infiltered in soil, influence soil, the groundwater regime on periphery.
《The composition and structure of manganese mud》(Shanghai building materials institute journal, the 1st phase in 1992, Wang Yanlong etc.) one literary middle finger
Go out：Electrolytic manganese residues are mainly made of nonactive mineral submellite, akermanite and a small amount of vitreum, and it contains distributed pole not
Uniform MnO.《Binding Material Made of Waste Electrolyzed Manganese Slag》(silicate building products, the 4th phase of nineteen ninety-five, Ke Guojun's etc.) grinds
Study carefully in result and show：Electrolytic manganese residues density is 2.72g/cm3, chemical composition has SiO2、CaO、SO3、Fe2O3、Al2O3.《Electrolysis
The comprehensive utilization of metal manganese waste slag》Pointed out in (nation manganese industry, the 16th phase in 1998, Liu Shengli)：Manganese slag mainly contains SiO2、
CaO, Mn element and minimal amount of non-ferrous metal element；Manganese slag sample contains 13 kinds of mineral, and wherein silicate mineral is opposite contains
Amount is very high, occupies second；Its grain graininess is thinner, and 81.58% particle diameter is below 38 μm.《The physicochemical characteristics of electrolytic manganese residues and
The research of its development and application》Drawn the following conclusions in (nation manganese industry, the 2nd phase in 2006, Li Tan equalitys)：With the male industry in Hunan day
The manganese slag of Co., Ltd is research object, finds to remove SiO in chemical composition2Outside, there are potassium sodium basic anhydride；Its grain graininess
83.33% is accounted for below 30 μm.《The fundamental characteristics of manganese slag and the progress in concrete》(concrete, 2012
2nd phase, the Zhou Dynasty army etc.) in, in addition to the chemical composition, mineralogical composition and particle characteristic that analyze manganese slag, it is specifically that electric
Solution manganese slag contains certain lateral reactivity.The domestic comprehensive utilizating research to electrolytic manganese residues is relatively more, but for manganese ore acid-soaked waste residue
The research of comprehensive utilization or fewer.
Manganese ore acid-soaked waste residue be manganese ore by sulfuric acid chemistry wet production manganese sulfate during the filtering waste residue that produces, again
Referred to as manganese ore phase analysis.According to incompletely statistics, the manganese ore phase analysis of the manganese processing enterprise discharge in Guangxi District adds up to millions of
Ton.Manganese ore phase analysis is a kind of inertia silica-aluminum materials rich in sulfate, and sulfate radical content is up to 15%~25%.From world's model
Analysis is enclosed, manganese ore phase analysis can be described as the characteristic slag for belonging to China, and foreign countries are since yield is few or does not have so as to its achievement in research
It is substantially zeroed.For industrial chain angle, a large amount of stockpilings of manganese ore phase analysis are unfavorable for the development of manganese ore processing enterprise of China.Due to
Manganese ore phase analysis viscosity is big, moisture content is high, without pozzolanic activity and sulphates content it is high the features such as, it is difficult to recycling effectively sharp
With.Analyzed from available data, research of the China to manganese ore phase analysis is still in infancy.The present invention is by the thing to manganese ore phase analysis
Reason and chemical property research and exploratory experiment, it is found that manganese ore phase analysis also can be as the raw material for making Industrial Residue Brick, to a certain degree
On perhaps can solve the problems, such as construction material shortage of resources.
In recent years, Industry Waste slag brick has become one kind of China's energy saving construction material, is developed rapidly.It is one
Kind mainly based on bearing wall brick, the cementitious material that is equipped with by various industrial residues cement and lime etc., and outside some
Add agent and manufactured brick body.Signified non-autoclaved and unburned manganese ore acid-soaked waste residue brick of the invention is using manganese ore acid-soaked waste residue to be main former
Material, technical process are using method free of calcining and steam curing come the building block for preparing.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind non-autoclaved and unburned manganese ore acidleach is prepared using manganese ore acid-soaked waste residue
The method of Industrial Residue Brick, the manganese ore acid-soaked waste residue utilization rate of this method is high, energy consumption is small, simple process, obtained manganese ore acid-soaked waste residue
Brick has excellent mechanical property.
The present invention solves above-mentioned technical problem with following technical solution：
A kind of method that non-autoclaved and unburned manganese slag brick is prepared using manganese ore acid-soaked waste residue, by setting after each brick-making raw material is pre-processed
Certainty ratio weighs plus water, batch mixing, die-filling, extrusion forming, it is characterized in that processing step is：

The multiple mode of equivalent adds water mix into half siccative；
(3) half siccative is loaded into mould, compressing under a certain pressure, maintenance more than 28d can be prepared by finished product.
Drying in pretreatment, is that the bulk manganese ore acid-soaked waste residue that will be dispatched from the factory is placed in outdoor clean ventilation vacant lot drying 5-7
My god.
It is broken in pretreatment, it is by bulk manganese ore acid-soaked waste residue Po Sui Cheng≤10cm fritters after drying.
Drying in pretreatment, be will it is broken after waste residue be placed in dryer and be dried to moisture≤3%.
Grinding in pretreatment is that the waste residue after drying is placed in ball mill grinding to 100~150 mesh.
Batch mixing is to pour into pretreated manganese ore acid-soaked waste residue powder, cement, white lime and flyash by weight respectively
In batch mixer, using the multiple water supply way of equivalent, moisture is gradually sprayed in dry mixture for 4-6 times, is adding water process
In be stirred continuously and water is uniformly dispersed, mix is into half siccative.
Compressing is that uniform half siccative of mix is placed in molding die, is gradually pressurized to 15-20MPa, and protecting
Demoulded after holding pressure about 5min.
Maintenance is that the product after the demoulding is placed under standard conditions to conserve.(condition is 20 DEG C ± 2 DEG C of temperature, relative humidity
More than 95%RH).
