Why you don't dissolve gold in aqua regia ? It is very safer than cyanide

He wants to precipitate gold from cyanide solution. Anybody can help him?

goldandsilver123 said:We used this recipe, there's large excess of zinc but it works:
Add 25 g of NaOH per liter
Add 12x the amount of dissolved gold in zinc dust. (1g of gold = 12g of zinc)
the zinc is added little by little with vigorous stirring.
When you master this, you should go to electrolysis.

Please search in forum. You will learn many things here but you must read and read
Does coconut water activated carbon can absorb gold , or it should be specialist for gold , because in my country only available carbon for water treatment with size 6x12Hello
Firstly- not sure whether mixing sex with cyanide is a good idea.
Secondly you're looking at the maths incorrectly- the amount of active carbon that's required depends upon:
Gold loading in solution
Other metals loaded into solution.
It's not a per litre basis unless you've got an AAS reading telling you how much gold is there per litre, and even then it depends on the other metals too because the active carbon will take it all out. The total weight of metals will contribute to the loading of the carbon.
