The titled method is formed in a three-step way in which hot gases of zinc vapor pass through at least three different condensation chambers from a first chamber to a last one. And later the hot gases were counter-currently passed through the condensation chambers from the last chamber to the first one continuously generating a spray of molten lead droplets of the condensation chambers each by rotating recyclely at least one impeller immersed in molten lead of the condensation chambers to condense the zinc vapor.
