Yes, VERY good info. That was written by Robin Grayson - aka: Steppegold. Quoted from another forum, "Robin is a British Geologist who lives in Mongolia and works in many areas in that part of the world."

Another site with all of that info (for free) is http://www.mine.mn/Robin_Grayson_gold_recovery.htm ....Curious - the site seems to be down at the moment.

Try this. http://www.goldivanti.com/files/Gold-Recovery-Methods.pdf
Or this. 75 Gold Recovery Methods

You have to open each method individually instead of reading like a book.

I noticed in the "Chlorine – chemical leaching of gold"
2
nd
stage – recovering gold from solution
The liquid is decanted from the bucket and filtered.
The filtrate includes leached gold as gold chloride
aqueous
.
To precipitate the gold from the pregnant solution,
several methods are available: sodium metabisulphate,
Sodium metabisulphite will precipitate gold not sulphate

Well, guess that goes to show you can't believe everything you find online.

Is probably a typo - but I wouldn't know!! Hoping to try my hand at mining some day but "that day" seems to be getting farther and farther away.

Hi KCM, wondering if you still have a full copy of the Gold Miners Handbook by Robin Grayson. Be chasing a copy but cant seem to find it anywhere, except individual pages on Scibd.
