Embodiment 1
[0048] (1) Mix the desulfurization ash and the rock-stripping tailings particles evenly, wherein the total mass of the desulfurization ash is 10% of the total mass of the rock-stripping tailings particles, take a certain amount of samples, place them in an oven at 105°C and heat them to constant weight, And the CaSO in the mixture was determined by iodometric method 3 The content accounts for 2.8% of the total mass of the mixture;
[0049] (2) Spray water accounting for about 10% of the total mass of the mixture in the mixture;
[0050] (3) Use cotton cloth to cover the mixture, and sprinkle about 5% water of the total mass of the mixture to the mixture every 7 days for maintenance, and continue to maintain for 8 weeks;
[0051] (4) After 7 days from the last replenishment of water, remove the cotton cloth, let the mixture dry naturally for 3 days, take a certain amount of samples, place them in an oven at 105°C and heat them to constant weight, and measure the CaSO in the mi...
Embodiment 2
[0053] (1) Mix the desulfurization ash and the rock-stripping tailings particles evenly, wherein the total mass of the desulfurization ash is 15% of the total mass of the rock-stripping tailings particles, take a certain amount of samples, place them in an oven at 105°C and heat them to constant weight, And the CaSO in the mixture was determined by iodometric method 3 The content accounts for 4.8% of the total mass of the mixture;
[0054] (2) Spray water accounting for about 10% of the total mass of the mixture in the mixture;
[0055](3) Use cotton cloth to cover the mixture, and sprinkle water of about 7% of the total mass of the mixture to the mixture every 7 days for maintenance, and maintain for 9 weeks;
[0056] (4) After 7 days from the last replenishment of water, remove the cotton cloth, let the mixture dry naturally for 3 days, take a certain amount of samples, place them in an oven at 105°C and heat them to constant weight, and measure the CaSO in the mixture by i...
