Abstract
Improvements made to the object of main patent no. 388,474, granted on March 1, 1973 > by: Procedure for the separation of mercury from the residual chlorine-containing brine from a mercury cell, which comprises adding sulfide or hydrosulfide ions to the brine in an amount sufficient to produce a redox potential of the brine, with respect to an electro of saturated KCl-calomelanes, with a value more negative than +0.45 volts, with which mercury sulfide precipitates; and separating the precipitated mercury sulfide by paying the brine down through a filter comprising at least two directly overlapping layers of granular filter material, decreasing the average size of the granular material particles in the successive overlapping layers and increasing the density specific granular material from the top of the filter down; characterized by comprising separating the precipitated mercury sulfide from the filtered by treating the latter with a liquor that dissolves the mercury sulfide; and extract the mercury-rich liquor thus obtained.
