Abstract: Способ получения металлического палладия относится к гидрометаллургии благородных металлов и может быть использован для получения палладия в виде металла. Палладий в виде соли растворяют, а затем восстанавливают до металла муравьиной кислотой. Техническим результатом является предотвращение самопроизвольного вспенивания пульпы в процессе восстановления и образования «зеркала» за счет восстановления палладия на стенках реакционного оборудования. Для этого растворение соли палладия проводят в растворе гидроксида натрия с концентрацией 80-150 г/л, полученный раствор прогревают в течение 0,5-1,5 часов. Металлический палладий отделяют фильтрацией, промывают и проводят термическую обработку. 1 табл., 2 пр.
