Production methods

1. Insert the platinum as anode, in the purification of gong, insert another foil as the cathode 15% (mass) of dilute nitric acid (not touching the mercury) at the bottom of the electrolytic solution, purification of mercury and the proportion of dilute nitric acid for 10 kg: 1000 ml, electrolytic voltage for 2-3 v, current for 3-4 a.At the start of the electrolysis, stirring constantly, electrolyte to join a new electrolyte.Continue to electrolytic until electrolyte not darker color.Acid, water washing to small acid content of qualified, add such as volume of mercury in smoke wash a bottle with water, using the method of vacuum air ventilation with mercury and the smoke wash water until the upper no longer appear turbid water, to remove mercury amalgam.To the upper water, mercury surface with filter paper blot, namely for the purification of mercury.For preparing high purity mercury, the mercury in the washing column of smoke wash with 5% of the reagent nitric acid and water washing (calculate mercury surface must be clean), with four layers of fine gauze filter the surface with filter paper blot, vacuum distillation, vacuum degree is 4665-6665 pa, collected 120-140 ℃ fraction, for a quick high purity mercury.
2. At present in the industrial production of mercury is given priority to with fire, wet vice.The method is simple, low production cost.In oxidizing atmosphere and the mercury stone 650 ~ 750 ℃ temperature roasting, make it into sulfur dioxide and metal mercury.Mercury vapor with the furnace gas escape, in condensed liquid in the cooling system, about nine grade can be got
9 5% of the mercury "MAO", through the deerskin and canvas filtered, as a general industrial use mercury.Wet smelting mercury is mainly used for processing of mercuric sulfide concentrate.With 25% of sodium sulfide and the mixture of caustic soda solution from HgS ore leaching, then a diaphragm electrolytic solution with graphite as the anode, mercury as the cathode, electrolytic mercury purity can reach more than 99.99%.Commercially available mercury often contains impurities, if need to pure mercury, according to the following method in the laboratory for further purification.Purification method...

use

Used for the synthesis of mercury compounds, or as a catalyst, paint, coatings, etc.;Some still as medicine, oral, excessive inhalation of the dust and the skin coating can cause poisoning.
