Claims (1)
7. Способ по п.6, отличающийся тем, что кислоту используют в количестве, при котором количества ионов водорода, обеспечиваемых кислотой, достаточно, чтобы прореагировать со связанным кислородом в системе после добавления комплексообразующего агента.6. The method according to claim 5, characterized in that the complexing agent is used in such an amount that the ratio of the molar content of the complexing agent to the molar content of the starting material corresponds to the formula
7. The method according to claim 6, characterized in that the acid is used in an amount in which the amount of hydrogen ions provided by the acid is sufficient to react with the bound oxygen in the system after adding the complexing agent.
12. Способ извлечения металлического олова из оловосодержащего исходного материала, заключающий в том, что осуществляют контактирование оловосодержащего исходного материала с минеральной кислотой и комплексообразующим агентом при температуре и давлении, подходящих для образования комплексов нерастворимых фторидов и растворения по меньшей мере части не-оловянных металлических составляющих, присутствующих в рудном шламе, и растворяют образовавшиеся оловосодержащий материал и раствор, полученный после растворения.11. A method of reducing the concentration of radioactive metal components present in a metal-containing material containing radioactive material provides for contacting the metal-containing material with mineral acid and a complexing agent for cooking ore sludge at a temperature and pressure suitable for forming a complexing agent and fluoride complex and dissolving by at least parts of at least one metal component present in the ore sludge and the solid formed other substances and the solution obtained after dissolution,
12. A method of extracting tin metal from a tin-containing starting material, which method comprises contacting the tin-containing starting material with a mineral acid and a complexing agent at a temperature and pressure suitable for forming insoluble fluoride complexes and dissolving at least a portion of the non-tin metal components, present in the ore sludge, and the formed tin-containing material and the solution obtained after dissolution are dissolved.
