Concretely comprise the following steps and this matt Cu-S ore difficult to understand is added among the ore pulp of microfine Pb-Zn tailings, mixed, Zhi Hou
Start sedimentation under acid condition, treat to settle completely added with the microfine Pb-Zn tailings of this matt Cu-S ore difficult to understand, complete whole sedimentation
Process, reaches the treatment of wastes with processes of wastes against one another, settles the purpose of particulate Pb-Zn tailings ore pulp.
Preferably：
The first step, by weight 1:This matt Cu-S ore difficult to understand of+0.3mm grades is added to the zinc of lead containing microfine by 10 ratio
In the ore pulp of mine tailing, 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 Ao Simai
The microfine Pb-Zn tailings of special Cu-S ore are settled completely, complete whole infall process.
In above-mentioned preferred scheme second step, in acid condition, added with the microfine Pb-Zn tailings of this matt Cu-S ore difficult to understand
It can just be settled completely within 10min.
This matt Cu-S ore single point surface area difficult to understand is 0.7325 (m2/ g), specific surface area is 0.7404 (m2/ g), pore volume
0.00126(cm3/ g), pore size 68.0996 (angstrom).This matt clinker difficult to understand is what is occurred in the range of 0~0.5 in relative pressure
Lag loop comes from N2Capillary condensation, contain the uniform cylindric mesopore of a large amount of both ends opens.The slag rough surface has many
Mostly below 5 microns, there is partial gap between particle in irregular blocky-shaped particle attachment, particle.The slag particle footpath is substantially 50
Micron is following, and only small part particle is in 50 microns, and with the presence of part fine grained surface crack, and these show that the slag can
Open space can be contained.This matt Cu-S ore difficult to understand is after pulverizing and jevigating to certain fineness, to the lead zinc tail of microfine in ore pulp
Ore deposit has flocculating setting effect, and efficiency is higher, and because this matt Cu-S ore difficult to understand 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 this matt Cu-S ore difficult to understand；2. with 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 adsorption method compare, in the case where the sedimentation time is more or less the same, and this matt Cu-S ore difficult to understand has in Costco Wholesale
Clear superiority, therefore a kind of this matt Cu-S ore difficult to understand disclosed by the invention settles the side of microfine Pb-Zn tailings as flocculant
Method, 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：This matt Cu-S ore difficult to understand is added among the ore pulp of microfine Pb-Zn tailings, entered
