| abstract | The process comprises forming the sulphides of said metals by means of hydrogen sulphide gas under pressure and separating by means of filtering. The reaction is carried out by means of gas-liquid contact apparatus of the T-reactor type and filling towers, with reduced residence times of less than 10 minutes. The reaction is practically stoichiometric, the acidity of the water can be less than 1% SO4 H2 by weight, thus obtaining a residue of SH2 in the water of less than 500 ppm, which can be removed by blowing air after the filtering of arsenic sulphide and precipitated metals. The plant basically consists of T-mixing reactors, two-stage pressure reaction towers, a filter press, a degassing tower and an alkaline absorption tower. |
