| titleOfInvention | Method for obtaining metallic silver from argentum chalcogenide |
| abstract | FIELD: metallurgy. n SUBSTANCE: invention refers to method for obtaining metallic silver from its chalcogenide. Method consists in its mixing with alkaline agent, mixture roasting and sinter processing by water with metallic silver residue separation. Alkaline agent is equimolecular mixture of nitrate and sodium nitrite taken in quantity 105-110% of stoichiometry of argentum reducing reaction. The roasting is done at 375-400°C with nitrogen dioxide separation and formation of sinter that contains argentum and sodium chalcogenate. Water processing is done without sinter preliminary cooling. Decrease of roasting temperature reaches 125°C, the consumption of alkaline agent reduces by 8.3-30%. n EFFECT: obtaining of powdered metallic silver at complete argentum reduction in conditions of one-stage roasting. n 4 cl, 8 ex |
