In this reaction, each silver atom loses one electron to a chlorine atom. The silver atom becomes "one electron short" of what it usually has. The one-electron-short silver atom is called a silver ion ...
The key output of the chlorine refining process is silver chloride, which enters a silver leaching process to remove the base metals. The silver chloride is then reduced to metallic silver and is then refined by electrolysis.
Using Chlorine to Produce Pure Radium Producing RaCl 2 from ore was an important intermediate step in producing pure radium. The Curies noted that radium behaved chemically very similarly to the element barium with which it was mixed in the ore, and that they would have to devise a method to separate radium from barium in processing pitchblende.
of chlorine per tonne of ore and then . 68 ADVANCES IN GOLD AND SILVER PROCESSING increased to 50 kg per tonne. Highly refractory ores might require over 100 kg per tonne to yield more than 83 per cent gold by cyanidation. Sawyer and Hendrix (1988) had investigated the effect of sodium ...
Silver is found in native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver).
II. Gold Ore Roasting: When the analysis was complete, some of the ore was chlorinated in a manner to be explained later, and it was found that no practically important extraction could be obtained, due to the fact that the sulphur absorbed a large part of the chlorine and that the gold was not in a suitable form to be attacked by chlorine.
Chlorination Chlorination and Amalgamation Patio Process. The patio process for silver was invented by a miner in Pachuca, Mexico, in 1557. The dry crushed ore was moistened and mixed with copper sulphate, common salt, and mercury, the working and aging of …
Sep 04, 2009· An organic compound was synthesized and found to contain only C, H, N, O, and Cl. It was observed that when a 0.150 g sample of the compound was burned, it produced 0.138 g of CO2 and 0.0566 g of H2O. All the nitrogen in a different 0.200 g sample of the compound was converted to NH3, which was found to have a mass of 0.0238 g.
Chlorargyrite, also called cerargyrite, is and/or was a locally important silver ore mineral.It forms isolated and fleetingly small but rich deposits of silver ore. It the western USA, many a ghost town sits near what was a rich and at least temporarily profitable chlorargyrite deposit.
Silver ore is very rarely found isolated in individual nuggets of pure silver. It is much more common for silver ore to be found fused with other minerals such as sulfur, arsenic, antimony or chlorine.

Silver chloride is a chemical compound with the chemical formula Ag Cl.This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl + and Pb 2+).Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by greyish or purplish coloration to some samples.
