Gold processing equipment example. The discharge from the Unit Cell is higher than the feed inlet, thus making it possible to place the Unit Cell in the ball mill classifier circuit without an elevator or pump. Still another important unit in these cyanide circuits is the Spiral Rake Thickener with the beam type, lowhead superstructure.
This PYREX® cyanide distilling apparatus is used in testing for soluble and insoluble cyanides in water.Cyanide as hydrocyanic acid is released from cyanide complexes by means of a reflux distillation and absorbed in a scrubber containing a sodium hydroxide solution.
A cyanide is a chemical compound that contains the group CN. This group, known as the cyano group, consists of a carbon atom triple bonded to a nitrogen atom.. In inorganic cyanides, the cyanide group is present as the anion CN .
