خدمة عبر الانترنتArgentite is the high-temperature form of acanthite. Like several other sulfides, selenides, and tellurides of silver and copper, argentite forms isometric crystals at high temperatures. Upon cooling these crystals invert from isometric (cubic) to monoclinic structures while remaining unchanged in external appearance.

خدمة عبر الانترنتThe argentite ore dissolves in sodium cyanide forming sodium argento cyanide. The reaction is reversible so is passed to oxidize Na2S to Na2SO4 such that the equilibrium shifts towards the product. The solution is filtered and the filtrate containing sodium argento cyanide is used to recover silver metal.
خدمة عبر الانترنتIn mineralogy, argentite is cubic silver sulfide (Ag 2 S), which can only exist at temperatures above 173°C, 177°C, or 179°C. It contains 87% silver and forms blackish-gray coatings or masses with a metallic luster and a shining black STREAK. When it cools to ordinary temperatures it turns into its monoclinic polymorph, acanthite.
