Abstract

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.

使用氟氢化铵和硫酸盐混合物分解矿物原料

研究了含金岩石和含钛矿物原料与氢氟化铵 NH4HF2 和硫酸铵 (NH4)2SO4 混合物在 430°C 以下温度下的相互作用。对比分析表明，与单独使用氢二氟化铵相比，使用 NH4HF2 和 (NH4)2SO4 的混合物能更彻底地赢得矿物原料。建议将 NH4HF2 和 (NH4)2SO4 的混合物作为一种新的有前途的试剂，用于分解岩石和矿物原料，以便在水浸出过程中将产品完全提取到溶液中。
