Abstract
A kind of method the invention discloses copper flash clinker as flocculant sedimentation microfine Pb-Zn tailings, it belongs to water process environmental technology field.Copper flash clinker is added in the ore pulp of microfine Pb-Zn tailings, is mixed, starts to settle later in acid condition, to be settled completely added with the microfine Pb-Zn tailings of copper flash clinker, entire infall process is completed, the treatment of wastes with processes of wastes against one another is reached, settles the purpose of particulate Pb-Zn tailings ore pulp.The present invention has found that copper flash clinker is a kind of good flocculant by settling the experimental study of microfine Pb-Zn tailings to copper flash clinker, can dramatically speed up the sinking speed of fine granule material.The advantages such as this method has simple process, low in cost, sinking speed is fast can be improved the utility value of copper flash clinker, improve the flocculating setting of microfine Pb-Zn tailings, have important environment protection significance and good application prospect.
Description
Technical field
A kind of method the present invention relates to copper flash clinker as flocculant sedimentation microfine Pb-Zn tailings, it belongs to Shui Chu
Manage environmental technology field.
Background technique
During copper flash clinker is Copper making, the waste residue that water cooled fast cooling generates, is that one kind has after cooling
Very the vitreum material of high activity and a kind of silicate material rich in porous micropore, copper flash clinker Minerals composition are exhausted
Most of is the sulfide of magnetic iron ore and a small amount of copper, and gangue mineral is mainly pyroxene and the nature of glass.At present to copper flash clinker
Comprehensive utilization aspect is carried out except through dressing method outside the recycling of the resources such as copper, iron, moreover it is possible to be widely used as other products
Raw material, be such as applied to cement manufacturing industry and iron powder replaced to make additive, for producing Portland clinker, be used as slag
Cotton material is used as colour glazed tile and corrugated tile material etc..The present invention comprehensively consider copper flash clinker flocculating setting effect and
Cost advantage seeks a kind of method that copper flash clinker settles microfine Pb-Zn tailings as flocculant, has certain economy
Meaning and social benefit.
Summary of the invention
1. goal of the invention:
A kind of method the purpose of the present invention is to provide copper flash clinker as flocculant sedimentation microfine Pb-Zn tailings,
Copper flash clinker is used as the flocculating setting agent of microfine Pb-Zn tailings by this method, is turned waste into wealth, while can reduce copper flash
Environmental pollution caused by the stacking of clinker causes great risk to the life and health of the mankind, realizes that resource environment green coordinates hair
Exhibition.
2. technical solution:
Technical solution of the present invention: a kind of method that copper flash clinker settles microfine Pb-Zn tailings as flocculant, specifically
Step is that copper flash clinker is added in the ore pulp of microfine Pb-Zn tailings, is mixed, later in acid condition
Under start to settle, to settle completely added with the microfine Pb-Zn tailings of copper flash clinker, complete entire infall process, reach with useless
Control useless, the purpose of sedimentation particulate Pb-Zn tailings ore pulp.
Preferably:
The copper flash clinker of+0.3mm grade is added to Pb-Zn tailings containing microfine by the first step, the by weight ratio of 1:10
Ore pulp in, then carry out mixing stirring；
A small amount of sulfuric acid is added in second step, be maintained at acid condition pH be 6 under conditions of, start to settle, to added with copper flash
The microfine Pb-Zn tailings of clinker settle completely, complete entire infall process.
In above-mentioned preferred embodiment second step, in acid condition, exist added with the microfine Pb-Zn tailings of copper flash clinker
It can be settled completely within 10min.
Copper flash clinker single point surface area is 0.7644 (m2/ g), specific surface area is 0.7438 (m2/ g), Kong Rong 0.001381
(cm3/ g), pore size 74.2498 (angstrom).Flash clinker is the lag loop source occurred in 0~0.4 range in relative pressure
In N2Capillary condensation, contain the uniform cylindric mesoporous of a large amount of both ends opens.Loosely there is more gap between particle, and
Many irregular blocky grain diameters are less than 10 microns.The slag has that particle largely less than 10 microns is big and a small amount of partial size is 30
The particle of microns.Copper flash clinker has the Pb-Zn tailings of microfine in ore pulp after pulverizing and jevigating to certain fineness
Flocculating setting effect, and efficiency is higher, and since copper flash clinker is a kind of tailings, it is extremely low using cost.
3. the utility model has the advantages that
Beneficial effects of the present invention: 1. reduce environmental pollution caused by the stacking of copper flash clinker；2. use is more cheap
Price sedimentation Pb-Zn tailings ore pulp, the treatment of wastes with processes of wastes against one another.At identical conditions, the method for the present invention and existing flocculating setting agent and
Adsorption method compares, and in the case where being not much different the sedimentation time, copper flash clinker has the clear superiority in Costco Wholesale,
Therefore method of a kind of copper flash clinker disclosed by the invention as flocculant sedimentation microfine Pb-Zn tailings, has certain warp
Meaning of helping and social benefit.
Specific embodiment
Below with reference to embodiment, the invention will be further described.
The present invention is implemented as follows: copper flash clinker is added in the ore pulp of microfine Pb-Zn tailings, mixed
Stirring is closed, starts to settle later in acid condition, to be settled completely added with the microfine Pb-Zn tailings of copper flash clinker, is completed
Entire infall process reaches the treatment of wastes with processes of wastes against one another, settles the purpose of particulate Pb-Zn tailings ore pulp.
Specific step is as follows:
The copper flash clinker of+0.3mm grade is added to containing microfine Pb-Zn tailings by the first step, by weight ratio 1:10
Ore pulp in, then carry out mixing stirring；
A small amount of sulfuric acid is added in second step, be maintained at acid condition pH be 6 under conditions of, start to settle, to added with copper flash
The microfine Pb-Zn tailings of clinker settle completely, complete entire infall process.
It, in acid condition, can be complete within 10min added with the microfine Pb-Zn tailings of copper flash clinker in second step
Bulk deposition.
The method disclosed in the present can achieve the effect that: 1. reduce the dirt of environment caused by the stacking of copper flash clinker
Dye；2. with the ore pulp of more cheap price sedimentation Pb-Zn tailings, the treatment of wastes with processes of wastes against one another.At identical conditions, the method for the present invention with
The technical indicator that existing flocculating setting agent and adsorption method compare is as follows:
1 index contrast table of table
As can be seen from Table 1, in the case where being not much different the sedimentation time, copper flash clinker has bright in Costco Wholesale
A kind of aobvious advantage, method that copper flash clinker settles microfine Pb-Zn tailings as flocculant disclosed by the invention, has certain
