[Problem] To provide: a method for processing iron and steel dust, which is more advantageous than a Waelz method in terms of energy and economy; a method for producing zinc; and a method for producing a staring material for iron and steel. [Solution] According to a method for processing iron and steel dust of one embodiment of the present invention, a calcium compound is added to iron and steel dust that contains zinc, said calcium compound containing an equivalent number of moles or more of Ca with respect to the number of moles of Fe in the iron and steel dust, and the iron and steel dust to which the calcium compound has been added is heated and reduced in a furnace. The ratio of the number of moles of Ca in the calcium compound to the number of moles of Fe in the iron and steel dust is adjusted to be 1.3 to 1.5 (inclusive).

Provided is a safety device, which can introduce a gas from the outside of a container but has no flow of molten aluminum to the outside from that gas introducing portion, in which the container inside is sealed to have no splashing danger when the safety device is removed, and in which no lever operation is required to improve the workability. The safety device comprises a piping unit (2) having a first open end portion (2a) and a second open end portion (2b), a first removable part (3a) attached to the side of the first open end portion (2a) for making the piping unit (2) removable with respect the later-described gas introducing portion of the container, a second removable part (3b) attached to the side of the second open end portion (2b) for making an air hose removable with respect to the piping unit (2), and a gas communication unit (4) arranged between the first open end portion (2a) and the second open end portion (2b) in the piping unit (2) and having a multiplicity of independent through holes (4a) acting as gas passages between the first open end portion (2a) and the second open end portion (2b).

[PROBLEMS] To feed molten metal to the outside of a container at an appropriate flow speed. [MEANS FOR SOLVING PROBLEMS] The device has an air hose connectable to a gas passage; a pressurized gas feeding part for feeding a pressurized gas to the container through the air hose and the gas passage; a measurement part for measuring the flow speed of the molten metal fed from the inside to the outside of the container through a flow passage and piping, the feeding of the molten metal being made by the pressurized gas flowing into the container through the air hose; and a control part for controlling the pressure value of the pressurized gas that is fed to the container, the control of the pressure value being performed such that the flow speed measured by the measurement part is set to a predetermined value.
