Hydrogen sulfide (H2S) can be used to precipitate heavy metals contained in mine tailings and other bodies of water.


We developed a highly innovative, efficient and fast process to produce hydrogen sulfide (H2S) on site. HydroS process has a lower production cost of hydrogen sulfide (H2S) than existing processes.


The use of hydrogen sulfide (H2S) leads, generally to better efficiencies of metal removal and generates a more compact, stable and reusable product unlike the respective hydroxides and carbonates that are generated with traditional methods.


Some advantages of Using Hydrogen Sulfide (H2S) is that

hydrogen sulfide (H2S) does not add impurities to the process where it is applied, it is not stored, but produced on site according on demand.
