Nitric-acid leaching of copper-electrolyte sludge

Article preview

The processes occurring at nitric acid leaching of copper-electrolyte slimes are described. The influence of firing temperature and concentration of nitric acid on the degree of transition of silver and related elements into solution is investigated. Optimal modes providing high extraction of silver into solution and concentration of gold in the insoluble residue have been established.

Ways to Improve the Quality of Technical Tellurium

Article preview

Methods of refining of tellurium of technical purity have been developed and introduced. Due to application of oxidative smelting and distillation industrial batches of tellurium were obtained, in which the content of guest impurities meets semiconductor grades.

Investigation of silver selenide behavior in aqueous solutions

Article preview

The behavior of silver selenide in the whole range of pH values has been studied using thermodynamic calculations and polarization measurements. Pourbae diagrams at temperatures of 25 and 80°C have been constructed. The forms of selenium in acidic and alkaline solutions were determined.

Study of chromite platinum-metal massifs of Russia

Article preview

This type of deposits is the main exploration target for Pt, Ir, Os, Ru. Inferred resources of platinum group elements (PGM) from Ray-Iz are estimated at several tons. Methods of separation of rich concentrates of platinum metals by mechanical enrichment have been studied. Hydrometallurgical technology of PGM concentrates extraction from chromite ores is recommended. The expediency of PGM precipitation during processing of chromite materials at chemical plants even at low PGM content is shown. The prospectivity of chromite ores of the Polar Urals as a source of PGMs is substantiated.
