Abstract

Способ переработки концентрата пыли аффинажного производства, включающий выщелачивание исходного продукта в растворе каустической соды, отделение нерастворившегося остатка от щелочного раствора, плавку нерастворившегося остатка с добавками, измельчение и переработку полученного при плавке донного тяжелого сплава как концентрата аффинажного производства, отличающийся тем, что перед выщелачиванием в растворе каустической соды исходный продукт распульповывают в воде, пульпу подкисляют добавлением кислоты до установления значения pH1-2 и подвергают цементационной обработке добавлением порошка железа.A method for processing dust concentrate from refining production, including leaching the initial product in a caustic soda solution, separating the undissolved residue from the alkaline solution, melting the undissolved residue with additives, grinding and processing the bottom heavy alloy obtained by melting as a refining concentrate, characterized in that before leaching into In a solution of caustic soda, the initial product is pulped in water, the pulp is acidified by adding acid until the pH1-2 value is established and subjected to carburizing treatment by adding iron powder.
