Which is the best method for Percipitiating gold from Cyanide ?

Hello ! the title say all.

i think that the best way,is: add to the cyanide, naoh to elevatr the ph to 11---Then add zinc powder to the solution and mix for around 10minutes ---then leave the solution to rest for at least2hours--put a piece of zinc metal in the side of the becker , in order that the gold liberated out of the gold cyanide by thre zinc powder does not reprecipate--the gold will settle--filtrate the solution and wash the powder with gold, with hot water ---them put this powder to dissolve in ar----- this is the method that i use
