1 Scope

This standard specifies the calculation method of cyanide leaching of gold-containing material zinc replacement of gold recovery process theory. This standard applies to gold ore, gold flotation concentrate, or gold ore, gold flotation concentrate calcined, and other bio-oxidation pretreatment cyanide process Zinc replacement of leaching gold extraction process.

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 Cyanide original gold-bearingmaterial (goldoreorgoldconcentrates) beforecyanideleaching Gold cyanide leaching material into the job before, in the middle of the standard direct cyanidation of gold ore, gold flotation concentrate, or gold ore, gold flotation Calcined ore, and other bio-oxidation pretreatment process gold-bearing material obtained. 2.2 Cyanide leaching cyanideleaching The process of dissolving gold in cyanide solution containing oxygen. 2.3 Zinc replacement zincdustprecipitation Added zinc dust in gold expensive liquid by displacement reaction of zinc and gold the gold precipitation method. 2.4 Theoretical work cyanide recovery theoreticalrecoveryrate Equal to the product of the leaching rate, washing rate, replacement rate. Depending on the amount of cyanide and various original product and analytical grade, obtained according to the theoretical formula The percentage of cyanide gold mud gold and gold content of the original. 2.5 Leaching rate leachingrecovery After grinding ore cyanide leaching, the washing operation, the total amount of dissolved solid gold and gold ore percentage of cyanide into the job. 2.6 Washing rate washingrate The percentage of total dissolved solids of gold and the amount of job losses washing gold solid gold and the difference between the amount of total dissolved. 2.7 Replacement rate precipitaterate After the replacement, and the difference between your and your liquid gold liquid gold liquid gold of the percentage of lean exhaust.
