Silver nanoparticles (AgNPs) were selectively concentrated from environmental water samples without disturbing their sizes and shapes by cloud point extraction (CPE) with Triton X114 (TX114). The highest extraction efficiency for AgNPs was obtained at about their zero point charge pH (pHPZC), which was ∼− for the studied AgNPs.
· Nanosized silver sulfide (αAg2S) particles were identified in the final stage sewage sludge materials of a fullscale municipal wastewater treatment plant using analytical highresolution transmission electron microscopy. The Ag2S nanocrystals are in the size range of 5−20 nm with ellipsoidal shape, and they form very small, loosely packed aggregates.

This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt mixes is a useful technique to smallscale operators experimenting with smelting techniques on goldsilver ores. It could also be used with small lots of sulfide concentrates.
Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the ProtoIndoEuropean h₂erǵ: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal is found in the Earth''s crust in the pure, free elemental form ("native silver ...

Extraction of silver as silver cyanide from silver sulfide was made possible using acetonitrile as the source of cyanide. The process of cyanidation took place through the oxidation of sulfide to sulfur oxides and cleavage of the C–CN bond of acetonitrile. The reaction .
EXTRACTING METALS FROM SULFIDE ORES Ronald Woods School of Science, Griffith University Nathan, Queensland 4111, ... etc. Silver sulfide minerals in the ore follow the lead sulfide stream and cadmium sulfide follows the zinc. Silver and cadmium are separated from lead and zinc, respectively, in the subsequent metal extraction processes.
Journal Article: Neutron activation determination of silver in rocks and minerals using organic sulfide extraction for silver separation
The growing production and widespread application of silver nanoparticles (AgNPs) have led to their release into the environment, where they are mostly transformed to silver sulfide nanoparticles (Ag 2 S NPs). Thus, speciation analysis of Ag 2 S NPs in environmental matrices is essential for understanding the environmental process and toxic effects of AgNPs.
A maximum extraction of % was achieved with the mol/L thiosulfate and the mol/L copper sulfate. It is shown that coppertothiosulfate ratio is an important factor in silver sulfide dissolution and oxygen is not needed to leach silver sulfide, which leads to the instability of the leaching system at high coppertothiosulfate ratio.
2002. Q. I know how to extract silver from waste fixer chemically but the process is somewhat difficult. I use the following chemicals sodium sulfide, caustic soda sodium nitrate borax soda ash this process finally I get the black powder which is to be melted at high temperature.
A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydrometallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electrodeposition of the cobalt and zinc from the strip ...
Usa Ammonia Extraction Of Gold And Silver. Gold and silver are extracted from their elemental state or from complex ores and alloys by leaching them with a solution containing ammonia, ammonium salts and one or more process is particularly effective for refractory gold ores including sulfide and carbonaceous ores.
