Abstract
The invention discloses a kind of method that granulated copper slag settles microfine Pb-Zn tailings as flocculant, it belongs to water process environmental technology field.Among the ore pulp that granulated copper slag is added to microfine Pb-Zn tailings, mixed, start sedimentation in acid condition afterwards, treat to settle completely added with the microfine Pb-Zn tailings of granulated copper slag, whole infall process is completed, the treatment of wastes with processes of wastes against one another is reached, the purpose of particulate Pb-Zn tailings ore pulp is settled.Experimental study of the present invention by settling microfine Pb-Zn tailings to granulated copper slag finds that granulated copper slag is a kind of good flocculant, can dramatically speed up the sinking speed of fine granule material.This method has the advantages such as technique is simple, with low cost, sinking speed is fast, it is possible to increase the value of granulated copper slag, the flocculating setting for improving microfine Pb-Zn tailings, with important environment protection significance and good application prospect.
Description
Technical field
The present invention relates to a kind of method that granulated copper slag settles microfine Pb-Zn tailings as flocculant, it belongs to water process
Environmental technology field.
Background technology
During granulated copper slag is Copper making, the waste residue that water cooled fast cooling is produced is a kind of to have very after cooling
The vitreum material of high activity, is also a kind of silicate material rich in porous micropore, and ore mineral is magnetic iron ore, a small amount of copper
The oxide of sulfide, elemental copper and copper, has no that the material that a small amount of doubtful clay mineral is seen in the nature of glass, another thin slice is spread.Mesh
In terms of the preceding comprehensive utilization to granulated copper slag in addition to the recycling of the resources such as copper, iron is carried out by dressing method, moreover it is possible to wide
The general raw material as other products, are such as applied to cement manufacturing industry to replace iron powder to make additive, for producing silicate cement
Mud clinker, as slag cotton material, as colour glazed tile and corrugated tile material etc..The present invention considers the wadding of granulated copper slag
Solidifying settlement action and cost advantage, seek a kind of method that granulated copper slag settles microfine Pb-Zn tailings as flocculant, have
Certain economic implications and social benefit.
The content of the invention
1. goal of the invention：
, should it is an object of the invention to provide a kind of method that granulated copper slag settles microfine Pb-Zn tailings as flocculant
Granulated copper slag is used as the flocculating setting agent of microfine Pb-Zn tailings by method, turns waste into wealth, while granulated copper slag can be reduced
Environmental pollution caused by stacking causes great risk to the life and health of the mankind, realizes resource environment green coordinated development.
2. technical scheme：
Technical solution of the present invention：A kind of method that granulated copper slag settles microfine Pb-Zn tailings as flocculant, specific step
Rapid is to be added to granulated copper slag among the ore pulp of microfine Pb-Zn tailings, is mixed, opened in acid condition afterwards
Begin to settle, treat to settle completely added with the microfine Pb-Zn tailings of granulated copper slag, complete whole infall process, reach the treatment of wastes with processes of wastes against one another,
Settle the purpose of particulate Pb-Zn tailings ore pulp.
Preferably：
The first step, by weight 1:The granulated copper slag of+0.3mm grades is added to the Pb-Zn tailings containing microfine by 10 ratio
In ore pulp, mixing stirring is then carried out；
Second step, adds a small amount of sulfuric acid, is maintained at acid condition pH under conditions of 6, to start sedimentation, treat added with water quenching copper
The microfine Pb-Zn tailings of slag are settled completely, complete whole infall process.
In above-mentioned preferred scheme second step, in acid condition, added with granulated copper slag microfine Pb-Zn tailings in 10min
Within can just settle completely.
Granulated copper slag single point surface area is 0.7430 (m2/ g), specific surface area is 0.7442 (m2/ g), pore volume 0.001311
(cm3/ g), pore size 70.468 (angstrom).Water Quenching Slag is that the lag loop occurred in the range of 0-0.6 comes from N in relative pressure2's
Capillary condensation, contains the uniform cylindric mesopore of a large amount of both ends opens.The slag surface is very coarse, there is obvious crack, and
Surrounding has irregular blocky-shaped particle of many particle diameters below 5 microns.It is big and few to there are a large amount of particles for being less than 10 microns in the slag
Particle diameter is measured in the particle of 50 microns, average grain diameter is in 30 microns.More loose and shape is relative to expensive between fine grained
Small stream slow cooling slag fine grained is shorter, more round.Granulated copper slag is after pulverizing and jevigating to certain fineness, to the lead zinc of microfine in ore pulp
Mine tailing has flocculating setting effect, and efficiency is higher, and because granulated copper slag is a kind of tailings, it is extremely low using cost.
3. beneficial effect：
Beneficial effects of the present invention：1. reduce environmental pollution caused by the stacking of granulated copper slag；2. use more cheap
Price settles the ore pulp of Pb-Zn tailings, the treatment of wastes with processes of wastes against one another.Under the same conditions, the inventive method and existing flocculating setting agent and suction
Subsidiary formula method compares, in the case where the sedimentation time is more or less the same, and granulated copper slag has the clear superiority in Costco Wholesale, therefore
The method that a kind of granulated copper slag disclosed by the invention settles microfine Pb-Zn tailings as flocculant, with certain economic implications
And social benefit.
Embodiment
With reference to embodiment, the invention will be further described.
What the present invention was realized in：Among the ore pulp that granulated copper slag is added to microfine Pb-Zn tailings, mixed
Stirring, starts sedimentation, treats to settle completely added with the microfine Pb-Zn tailings of granulated copper slag in acid condition afterwards, completes whole
Infall process, reaches the treatment of wastes with processes of wastes against one another, settles the purpose of particulate Pb-Zn tailings ore pulp.
Comprise the following steps that：
The first step, by weight proportion 1:10 are added to the granulated copper slag of+0.3mm grades containing microfine Pb-Zn tailings
In ore pulp, mixing stirring is then carried out；
Second step, adds a small amount of sulfuric acid, is maintained at acid condition pH under conditions of 6, to start sedimentation, treat added with water quenching copper
The microfine Pb-Zn tailings of slag are settled completely, complete whole infall process.
, in acid condition, just can be completely within 10min added with the microfine Pb-Zn tailings of granulated copper slag in second step
Sedimentation.
The method disclosed in the present can achieve the effect that：1. it is dirty to reduce environment caused by the stacking of granulated copper slag
Dye；2. the ore pulp of Pb-Zn tailings, the treatment of wastes with processes of wastes against one another are settled with more cheap price.Under the same conditions, the inventive method with
The technical indicator such as following table that existing flocculating setting agent and adsorption method compare：
The index contrast table of table 1
As can be seen from Table 1, in the case where the sedimentation time is more or less the same, granulated copper slag has obvious in Costco Wholesale
Advantage, the method that a kind of granulated copper slag disclosed by the invention settles microfine Pb-Zn tailings as flocculant, with certain warp
