Decomposition of Mineral Raw Materials Using a Mixture of Ammonium Hydrodifluoride and Sulfate
The interaction of gold-containing rock and titanium-containing mineral raw materials with a mixture of ammonium hydrodifluoride NH4HF2 and ammonium sulfate (NH4)2SO4 at temperatures below 430°C has been studied. A comparative analysis showed that the use of a mixture of NH4HF2 and (NH4)2SO4 allows more complete winning of mineral raw materials compared to the use of ammonium hydrodifluoride alone. The mixture of NH4HF2 and (NH4)2SO4 is recommended as a new promising reagent for the decomposition of rocks and mineral raw materials for complete extraction of the product into solution during water leaching.
