Cyanide Leaching Chemistry & Gold Cyanidation

 · The reaction for the dissolution of metallic silver in cyanide solutions is analogous to that for the dissolution of gold. The occurrence of metallic silver in ores, however, is not common; the silver is more likely to occur in the sulphide form either as the plain sulphide or in combination with sulphides of copper, arsenic, antimony and lead.

Silver - Wikipedia

Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table, copper and gold.Its 47 electrons are arranged in the configuration [Kr]4d 10 5s 1, similarly to copper ([Ar]3d 10 4s 1) and gold ([Xe]4f 14 5d 10 6s 1); group 11 is one of the few groups in the d-block which has a completely consistent set of electron configurations.

Silver: The mineral native Silver information and pictures

Silver has many unique physical properties that give it very special status. Silver is the best conductor of electricity, is the second most malleable and ductile metal, and is in greater abundance than all other precious metals with similar properties. Due to its unique properties and intrinsic beauty, it is extensively used industrially and as ornaments.

Nickel processing | Britannica.com

In the case of sulfides, the reaction of oxygen with iron and sulfur in the ore supplies a portion of the heat required for smelting. Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting.
