The invention discloses a dissolving and preparing method for a soap type collecting agent GY-10 agentia solution. The dissolving and preparing method comprises the steps that 1, a heating water tank (1) is arranged, the top of the heating water tank (1) is provided with a steam collecting cover (2), and the bottom of a heating water tank body is internally provided with a bracket (3) and a heater (4); 2, the top of the steam collecting cover is provided with a steam exhaust pipe (5); 3, an air exhausting and material discharging pipe valve (7) is inserted into a material discharging cover of each GY-10 agentia barrel (6); 4, the GY-10 agentia barrels are put into the heating water tank in a lifting mode and placed on the bracket, the water level of water in the water tank is higher than the level of the agentia barrels, and the level of air exhausting and material discharging pipes is higher than the water level; 5, the heater is started up to increase the water temperature gradually, and GY-10 agentia in the agentia barrels is melted gradually by water-bath heating; and 6, the water temperature is maintained consistently at 70-80 DEG C during heating, the heating time lasts for 40-60 min till all the GY-10 agentia in the agentia barrels is melted completely, and the melted GY-10 agentia is poured into a preparing and stirring barrel through the air exhausting and material discharging pipes for preparing and producing the required GY-10 agentia solution. The dissolving and preparing method for the soap type collecting agent GY-10 agentia solution is safe, efficient and easy to operate, energy is saved, and the agentia barrels can be recycled.
