Abstract
The invention discloses an all tailing cementing and discharging technology for metal mines. The technology comprises the following steps of: thickening tailings discharged by a metal mine concentration plant into 35-65 percent by mass of thick tailing slurry with a thickener; injecting into a stirring pool with a sand supply pipe and adding 1-6 percent by mass of gelled materials for stirring uniformly; concentrating and dehydrating into a dry material of which the water content is 15-25 percent with filtering equipment; and transferring and piling in mine collapse pits or appropriate places on the ground surface by using conveying equipment. In the technology, tailings are piled without building any tailing pond after being cemented, so that the conventional tailing pond discharge way is changed, and the potential safety hazard and environmental damage of the tailing pond are eliminated; and the technology has great economic benefit and social benefit.
Description
(1) technical field
The invention belongs to mine environment and administer the field, be specifically related to a kind of with the discharging of metallic ore dressing-works the tailings thickening and add the tailings draining technology that an amount of gelling material is stored up after fixed.
(2) background technology
Tailings belongs to the waste after the ore dressing, and is huge in the quantity discharged of China's tailings.Except that the minute quantity tailings was utilized, all the other overwhelming majority deposited in the mine tailing storehouse, the face of land.Using face of land mine tailing stock to put tailings deposits and wants a lot of problems: 1. take a large amount of soils; 2. directly cause environmental pollution; 3. the mine tailing stock is in potential safety hazards such as dam breaks.In addition, because the growing tension and the exhaustion of land resources suit to build the local fewer and feweri of mine tailing storehouse.
Hold not enough, tailings discharging difficulty for solving metal mine mine tailing Kuku; Eliminate potential safety hazard and environmental damage that the mine tailing library tape comes; For China's tailings processing provides a kind of new technological approaches; Propose the fixed draining technology of full tailings, the tailings that is about to the discharging of mine ore dressing factory utilizes the surface subsidence hole of mining formation to carry out the last person after thickening and consolidation process, or stores up other suitable places to the face of land; So just need not to build the mine tailing storehouse, also solved surface subsidence hole backfill simultaneously and also created condition for land reclamation.
(3) summary of the invention
(1) technological line and the technical process that the fixed row of the full tailings in a kind of mine stores up proposed
Technological line of the present invention: after thickening and consolidation process, backfill is cheated because of the surface subsidence that mining forms, or stores up other suitable places to the face of land with the tailings of mine ore dressing factory discharging.
Technical process of the present invention: it is the tailings underflow of 35%～65% (mass percent) to concentration that the tailings of mine ore dressing factory discharging at first adopts thickener dense; The tailings underflow stirs through the gelling material that supplies sandpipe and inject agitated pool and add 1%～6% (mass percent); Mixed slurry after the stirring is 15%～25% siccative by straining installation thickening to water ratio, changes draining into surface subsidence hole, mine or other suitable places are stored up again through handling equipment.
(2) confirm gelling material kind and minimum safe proportioning parameter thereof
The gelling material that the present invention adopted meets the requirement of general purpose portland cement among the GB175-2007, or adopts special-purpose full tailings cementing material to make gelling material; The gelling material volume is 1%～6% (mass percent), and tailings adhesive bond 28d intensity is 0.50MPa～2.0MPa.Bargh can guarantee to store up kind and the proportioning parameter thereof of confirming gelling material under the safe prerequisite as required.
(4) embodiment
(1) adopt thickener with the tailings of mine ore dressing factory discharging dense be the tailings underflow of 35%～65% (mass percent) to concentration;
(2) the tailings underflow stirs through supplying sandpipe and inject agitated pool and add the general purpose portland cement or the special-purpose complete fixed gelling material of tailings of 1%～6% (mass percent), forms mixed slurry;
(3) mixed slurry that stirs is 15%～25% siccative by straining installation (can adopt vacuum filter, automatic pressure filter or ceramic filter) thickening to water ratio;
(4) siccative after the thickening changes through handling equipment (can adopt endless belt conveyor, rail transportation equipment or trackless transportation equipment) and drains into surface subsidence hole, mine or other suitable places are stored up.
Claims (3)
1. the complete fixed draining technology of tailings is characterized in that: it is the mine tailing underflow of 35%～65% (mass percent) to concentration that the tailings of metallic ore dressing-works discharging at first adopts thickener dense; The mine tailing underflow stirs through the gelling material that supplies sandpipe and inject agitated pool and add 1%～6% (mass percent); Mixed slurry after the stirring is 15%～25% siccative by straining installation thickening to water ratio, changes draining into the face of land, mine and store up again through handling equipment.
2. the fixed draining technology of full tailings according to claim 1, it is characterized in that: said gelling material meets the requirement of general purpose portland cement among the GB175-2007, or adopts special-purpose full tailings cementing material to make gelling material.
3. the fixed draining technology of full tailings according to claim 1 is characterized in that: said mine tailing underflow straining installation can adopt belt vacuum filter, disc vacuum filter, automatic pressure filter or ceramic filter; Said siccative handling equipment can adopt endless belt conveyor, rail transportation equipment or trackless transportation equipment.
