    Abstract: A method of an essentially complete elimination of remaining traces of mercury in gases, such as roaster gases containing SO 2 , and which have been treated in a chloride washer for removing elementary Hg,. It is characterized in that the gas is introduced to a scrubber plant where the same is washed with a washing liquid such that any content of gaseous HgCl 2 . The gas is absorbed by the washing liquid and is subjected to a turbulent and mechanical action in the scrubber so as to physically put together any Hg, HgCl 2 and Hg 2 Cl 2 and other compounds of Hg present in particle or drop form into bigger aggregates or agglomerates. Thus formed aggregates or agglomerates and present bigger particles are brought to be separated from the gas and then be collected and removed. The invention may be completed with further steps for the elimination of any remaining mercury.
