The invention discloses a hydrogen metallurgy fuming zinc extraction method for a zinc-containing material. The zinc-containing material or the zinc-containing material and an auxiliary material is added into a fuming furnace, and hydrogen and combustion-supporting gas are introduced to heat and raise the temperature; when the temperature of the molten pool reaches 1000-1300 DEG C, the introduction amount of hydrogen entering the furnace is increased, a reduction blowing reaction is carried out at the temperature, in the reduction blowing reaction, oxide of zinc is reduced into elemental metal and volatilized in the form of metal steam, the metal steam is oxidized again in the upper space of the furnace chamber, enters a flue gas pipeline along with process flue gas and is treated and recycled, and finished zinc oxide is obtained; generated smelting waste slag is discharged through a slag opening, and is stockpiled or sold after being subjected to water quenching; and generated process flue gas is treated and
