Description
Technical field
The invention belongs to gold tailings recovery and reuse technology fields, and in particular to a kind of building of the particle containing gold tailings
Lightweight brick, and preparation method is further disclosed.
Background technique
In more than the 5000 years civilized histories in China, had for more than 4000 years using gold, as Egypt, India, ancient Roman at
To use one of gold and the country of other alloys earliest in the world.Gold column 79, atomic weight in the periodic table of chemical element
197, the big (19.32g/cm of golden density3) but be lighter than platinum.Golden color is golden yellow, and ductility is preferable, and 31.25g proof gold can hammer out ten thousand
The gold leaf of/mono- millimeters thick can stick 9m2Area.The volatility of gold is small, its golden volatile quantity melted under normal circumstances
It is insignificant.Fitting has good conductive and heating conduction, and conductivity is only second to silver and copper, and thermal conductivity is the 74% of silver.Gold
Chemical property is highly stable, will not aoxidize in low temperature or high temperature, does not work under room temperature with individual salt, nitre, sulfuric acid, but
Nitration mixture (chloroazotic acid) and cyanide solution but can good molten gold.Proof gold is seldom shown in that gold can be with other metal groups in nature
At alloy such as gold and silver, Jin Tong, yellow gold etc..
The exploitation of gold causes dependent on the type and reserves of gold ore deposit since most of gold ore gold content is extremely low
Almost how many tailing are just discharged in output how many ore in gold mining for manufacturing enterprise.Gold tailings are gold ores through levigate extraction
The waste discharged after gold concentrate powder is in yellow powder, there is lesser granularity and relatively uniform size distribution, containing more
SiO2、CaO、Fe2O3、Al2O3, MgO, have higher surface can and potential reaction activity.
The tailing that China's gold system is discharged every year is more than 24,500,000 tons, and since exploitation pattern is single, production practice is fallen
Afterwards, winning apparatus is outmoded, leads to a large amount of tailing remainings, can not effective recycling and reusing.Comprehensive utilization of tailing rate is very low at present, greatly
About 7%, remaining tailing is stored up generally as solid waste with the mode in mineral library, is not only taken up a large amount of soil, is caused
Tailings Dam ambient contamination, and substantial contribution need to be put into and build and safeguard for Tailings Dam.In addition, tailing itself is with super
Pollutant or harmful constituent are marked, the various chemical agents being added again in ore dressing process remain in tailing, are not passing through
Under disposition, it is directly deposited in earth's surface, a large amount of soil is not only taken up, also seriously polluted the environment of surrounding.
Therefore, gold mine comprehensive utilization of resources is had become for gold tailings comprehensive utilization and aspect of preserving the ecological environment
Important topic.
A kind of novel wall material using hollow brick as the lightweight brick of representative, have bulk density is light, thermal resistance is big, heat-insulation and heat-preservation,
The advantages that low in cost is the ideal material for replacing solid brick.Developed in the prior art prepared using tailings material it is hollow
The method of brick provides new approach to the recycling of tailings material.As Chinese patent CN103755379A disclose it is a kind of with
Iron tailings is the method that major ingredient prepares foamed hollow brick, is that preparation is former using existing iron tailings, clay, quick lime and foaming agent
Material, obtained hollow brick meet national examination criteria, can be used for construction material and be used.But foaming described in this method is handled
Step needs to complete at 1000 DEG C or so, and on the one hand excessively high temperature can destroy the quality of foaming, while also to foaming machine
It is required that.
