For the dissolution of the precipitating elementary sulfur an ester of an optionally mono- or poly-unsaturated fatty acid and/or the reaction product of H2S with an ester of a mono- or poly-unsaturated fatty acid, optionally in solution, is used, the solvent for sulfur being liquid under the conditions in the mining probe being sparingly soluble in the gas, and being added to the gas stream at a suitable place.
