[0039] Component 1: Portland cement clinker 9%

[0040] Component 2: Anhydrite 10%

[0041] Component 3: Quicklime 6%

[0042] Component 4: Na2SO4 0.2‰

[0043] Component 5: Hydroxymethylcellulose 0.2‰

[0044] Component 6: Fly Ash 5%

[0045] Component 7: Blast furnace water-quenched slag ground fine powder 69.96%

[0046] The above-mentioned components are accurately weighed, stirred evenly by a mixer, transported to a ball mill by a belt conveyor for grinding, and ground to a fineness of 380m2 / kg and then put into a finished product warehouse for standby.

[0047]When preparing the slurry, first mix the mining tailings with water to form a slurry with uniform concentration, add the consolidation agent into the slurry through a feeder, and mix the slurry in a mixer (twin-shaft mixer) 2 minutes to form a slurry with a weight concentration of 70%, and the slurry can be transporte...

Embodiment 2

[0051] The weight concentration of each component of the present embodiment is as follows:

[0052] Component 1: Aluminoferrite cement clinker 13%

[0053] Component 2: Phosphogypsum 15%

[0054] Component 3: Quicklime 6%

[0055] Component 4: Nacl 3‰

[0056] Component 5: Hydroxymethylcellulose 0.25‰

[0057] Component 6: Bauxite powder 7.05%

[0058] Component 7: Blast furnace quenched slag ground fine powder 58.625%

[0059] The above-mentioned components are accurately weighed, transported to a ball mill by a belt conveyor for grinding, and ground to a fineness of 400m 2 / kg and put it into the finished product warehouse for later use.

[0060] To prepare the slurry, mining tailings are mixed with water to form a 60% slurry which is transported underground where the cement is passed through feeders where it is pumped or gravity piped to the backfill ore Added to the slurry in the pipeline, the cement can be mixed with the slurry through the turbulent flow in the pip...

Embodiment 3

[0064] The weight concentration of each component of the present embodiment is as follows:

[0065] Component 1: Portland cement 17.54%

[0066] Component 2: Anhydrite 17.54%

[0067] Component 3: Quicklime 5.85%

[0068] Component 4: KCl 6‰

[0069] Component 5: Hydroxyethylcellulose 0.5‰

[0070] Component 6: High Calcium Limestone Powder 9.37%

[0071] Component 7: Blast furnace quenched slag ground fine powder 43.65%

[0072] The above-mentioned components are accurately weighed, transported to a ball mill by a belt conveyor for grinding, and ground to a fineness of 420m 2 / kg and put it into the finished product warehouse for later use.

[0073] When preparing the slurry, first mix the mining tailings with water to form a slurry with uniform concentration, add the consolidation agent into the slurry through a feeder, and mix the slurry in a mixer (twin-shaft mixer) 5 minutes to form a slurry with a weight concentration of 70%, and the slurry can be transported to t...

Abstract

The invention concretely relates to a novel tailing consolidator which uses fine powder ground from blast furnace water quenching slag as a main raw material and a preparation method of the consolidator. The consolidator is characterized in that the consolidator comprises, by mass concentration, 9 % to 17.54% of portland cement clinker, 10% to 17.54% of anhydrite, 6% to 10% of quicklime, 0.2 to 6 thousandths of Na2SO4, 0.2 to 0.5 thousandths of carboxymethyl cellulose, 5% to 10% of coal ash and 43.65% to 69.96% of the fine powder ground from the blast furnace water quenching slag. Each above component is dried by a dryer, put in a mixer to be evenly stirred, and conveyed to a bowl mill by a belt conveyer to be ground. The blast furnace slag discharged from a smeltery is used as the main raw material in the invention to reduce the cost and solve slag processing, so the consolidator has the advantages of low production cost, simple processing, and agile and convenient usage. A usage amount of the consolidator in the present invention is half or less than the usage amount of common cement under the same conditions with the same backfilling intensity.

Description

technical field [0001] The invention specifically relates to a novel tailings consolidating agent using blast furnace water-quenched slag ground fine powder as a main raw material and a preparation method thereof. technical background [0002] Along with the development of non-ferrous metal mineral resources, the mining of mines has brought huge wealth to people, but at the same time, it has left many goafs. If these goafs are not filled in time, it will lead to The surrounding rock mass collapses, endangering safe operation and normal mining. On the other hand, mining waste water, beneficiation tailings, slag and fly ash produced by smelting and power generation are discharged in large quantities, resulting in the waste of some resources. Moreover, the heavy metal pollutants will pollute the soil and water in the mining area, seriously destroying the natural environment and ecological balance of the mining area. At present, in our country, most of the mining wastes from no...
