A method for tempering high temperature slag and a mineral cotton production method belong to the metallurgical technical field of steel, ferronickel, ferromanganese, copper and the like. A tempering process is carried out by spraying coal ash, dolomite, aluminum ash and the like by using a heat-resistant spray gun, and the mixture is heated by using a heating agent in an oxygen blowing manner; moreover, by virtue of a sufficient condition of pouring hot slag into a slag tank in kinetics, the used equipment comprises a powder spraying system and an oxygen supply system. According to the components of the hot slag, a corresponding tempering agent is sprayed into the slag and the heating agents such as aluminum ash and the like are added to be in reaction with oxygen; the tempering agent is prompted to be fully mixed with the slag by virtue of flowability of the hot slag pouring into the slag tank so as to quickly form a silicate system; the heating agents are added, so that the slag temperature is not reduced, and a slag tank cover further covers the tank, so that the heat loss is reduced. Thereofe, the component is tempered into the slag blowing slag wool, the temperature of which is proper, and the viscosity is 1-3Pa.s. The problem that the slag is hardly mixed with the tempering agent and a temperature drop happens is solved. A melting furnace (an electric furnace) is not needed for secondary heating, so that the method has a relatively high economical benefit. The slag tank with a top cover is conveyed to a mineral cotton workshop and a travelling crane conveys the slag tank to a pouring site. Then, the slag tank is overturned by using a winch, and a slag fluid in a fixed quantity is controlled to enter a closed and heated blowing tank from an upper opening of the slag tank. The slag fluid in the fixed quantity enters the closed and heated blowing tank from the upper opening of the slag tank, so that the problem that in production of mineral cotton, the slag fluid amount is unstable as the height of the liquid level of a slag tank is different and the pressure of the liquid level is different in a manner that the melt is discharged from the bottom of the tank and the problem that the bottom-discharged slag blowing tank is blocked as the slag temperature is reduced are solved.
