TH13251B - A process for the derivation of mercury metal from products containing mercurous chloride. - Google Patents

Abstract

A process for obtaining metal mercury from products containing mercurous chloride involves the treatment of such products with aqueous solutions. Slightly acidic and Hot chloride There is a metal that can cause the valence attenuation of Hg + 2 as Hg and is in the form of mercury and other alloys. The same is true for bringing it back. Return of mercury in the form of metal

Claims (5)

1. A process for obtaining mercury metal from products containing mercurous chloride, particularly in connection with the treatment of such products with slightly acidic aqueous solutions. And a hot chloride solution containing metals that can attenuate valence of Hg + 2 to Hg ํ and occur as mercury alloys with other metals, as well as recovery methods of Hg + 2. mercury In the form of metal 2. Process according to claim 1, especially where the chloride concentration is set to be between 1 molar and saturation point, preferably 2 molar. 3. Process according to claim 1 or 2, especially in the salt part used as a chloride ion diffuser, it is a soluble salt which is better then sodium chloride. And ammonium chloride 4. The process according to claim 1, especially when it comes to the temperature of the application must be between 80 and 100 degrees Celsius 5. Process according to one of the claims 1,2,3 and 4 Especially in the part of the mercury that has been May be purified through washing In a solution with a 1 molar charge of chloride, where pH is between 1 and 1.5.
