Extraction of Platinum from Low-Concentration Refining Nitric Acid Solutions Using Electrolytic and Sulfide Precipitation
The results of platinum extraction from a low-concentration nitric acid platinum-containing solution by sulfide and electrolytic precipitation are presented. The problem of the study is the question about a possibility of platinum(IV) extraction from refining nitric acid mother liquors of a complicated ionic and quantitative composition. The best result for platinum extraction (99.9%) has been achieved for zinc-assisted electrolytic precipitation, and the subsequent nitric acid treatment of the cake provides a platinum–palladium concentrate with the platinum content at least 96.1%.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
