1. A fluidized solidified soil based on gold tailings, comprising the following raw materials in parts by mass: 75 parts to 80 parts of gold tailings, 5.2 parts to 13 parts of a dispersant solution, and 9 parts to 16 parts of a solidifying material; wherein
the gold tailings comprise the following chemical components by mass: SiO2: 66% to 76%, Al2O3: 10% to 16%, K2O: 6% to 10%, Fe2O3: 1% to 3%, Na2O: 1% to 2%, CaO: 0.12% to 1%, and TiO2: 0.1% to 0.3%, and have a particle size of less than or equal to 1 cm;
the dispersant solution is prepared by dissolving a dispersant in water and then regulating a pH value; the dispersant is compounded by the following raw materials in mass percentage: 45% to 60% of sodium hexametaphosphate, 15% to 30% of sodium tripolyphosphate, 5% to 15% of polyacrylamide, and 5% to 10% of polycarboxylic acid; and a pH regulator, wherein the pH regulator is a mixture of sodium hydroxide and sodium bicarbonate; and
the solidifying material is compounded by a mixture A of cement, blast furnace slag, fly ash, and a water reducer, and gypsum; the mixture A comprises the following raw materials in mass percentage: 50% to 60% of the cement, 30% to 40% of S95 granulated blast furnace slag, 5% to 10% of the fly ash, and 1% to 2% of the water reducer; and the gypsum, wherein the gypsum has a mass of 4% to 6% of a total mass of the cement and the S95 granulated blast furnace slag in the mixture A.
