A Novel Technique for Silver Extraction from Silver Sulphide Ore
A novel technique for silver extraction from Ag2S is described. The method utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved. The parameters of the reaction such as pH, the reaction temperature, the complex equilibrium of Ag ion with thiosulphate and the solubility of Ag2S were investigated. Silver ions, obtained by this me...
متن کاملExtraction of Silver From Photographic Waste
The waste photographic films/X-ray contains 1.5 2 % (w/w) black metallic silver which is recovered and reused. Around 18-20% of the world's silver needs are supplied by recycling photographic waste. Silver is a precious metal, further silver has wide uses like in jewellery, dentistry, photography, mirrors, optics, industries, etc. So the recovery of silver is beneficial in industrial, chemical ...
متن کاملChallenging Silver – Influence of Extraction Medium on the Release of Silver from a Wide Range of Commercial Silver Dressings
A number of antimicrobial silver dressings based on different substrates and silver technologies have been introduced recently. Initial in vitro testing of a new cost-effective silver dressing* showed a strong dependence between silver release and the ionic strength and organic content of the extraction solution. To answer the question if all silver dressings show similar dependence on extracti...
متن کاملExtraction of Silver Ions from Aqueous Solutions by Emulsion Liquid Membrane
A comprehensive study pertaining to the emulsion liquid membrane (ELM) extraction process to enrich dilute aqueous solutions of silver salt is presented. The study has highlighted the importance and influence of membrane composition for maximizing the extraction of Ag+ ions. The liquid membrane was made up of Cyanex-302 as an extractant and the industrial solvent mainly consists of p...
متن کاملNew Technology for Recovery of Gold and Silver by Pressure Cyanidation Leaching and Electrocoagulation
The present chapter describes a new technology of pressure oxidation/cyanidation leaching for the dissolution of gold and silver and the recovery of the precious metals by using the electrochemical process of Electrocoagulation (EC). The novel method demonstrates that the oxidation and dissolution of gold and silver in alkaline cyanide solution can be conducted simultaneously in the same reacto...
