· Silver nanoparticles (NPs) have been the subjects of researchers because of their unique properties (, size and shape depending optical, antimicrobial, and electrical properties).A variety of preparation techniques have been reported for the synthesis of silver NPs; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods ...

goldsilver ores. A procedure to extract silver from sulfide ores with FeC13 was patented by Hey in 1922 (6). Considera­ ble work was completed byWong (7) to re­ cover lead from a galena concentrate with a combined FeC13NaCl leach solution. Because both lead and silver were solu­ bilized, silver recovery from highsilver

Describing Chemical Reactions To know for certain that a chemical reaction has taken place requires chemical analysis for proof that one or more substances has undergone a change in identity However, certain easily observed changes usually indie that a chemical reaction has occurred 1. Evolution of heat and light 2. Production of a gas 3.
