OK thanks.I use a buckner funnel and a vacume hand pump.Then I like to use a spray bottle to wash the gold berring solution out of my filter.Can you add to much water and cause problems,say if were working with 100ml of poorman ar how much water would be to much.Or will the gold still fall from a solution that has more water in it than acid.jimmydolittle said:Kill the nitric with urea, then filter.
I've never had one fail.Thank You Very Much.I have had problems with a couple batches but I have allway gotton my gold out of them in the end.I have read the hokes book.And for this batch I did'nt have time to add sodium nitrate little by little so I had an excess of nitric.qst42know said:If you need urea you are wasting chemicals.
How many times must your prepackaged recipe fail you before you stop and study the art?
Dang Phil dont jinkes me.Get me all worried about hurting myself.I do take proper saftey mesures.I work all meterals outdoors and any time I'm near the solution weither it be filtering or anything I wear a gas mask with a NBC filter.While my cpu's are dissolving I dont go near it.philddreamer said:Cly wrote: "And for this batch I did'nt have time to add sodium nitrate little by little so I had an excess of nitric."
Cly, I hope you learned a valuable lesson.
"If you don't have enough time, don't start a process!" This is the main reason why many run into such problems, even serious injury & loss of values. Don't rush a process & don't skip the safe & proper steps.
Take care & be safe!
Phil

What? When I use the garden hose I end up with
At least 40-50 gallons of excess of water

Just so you guys and gals have a visual reference to what Harold is refering to by "concentrated", here is a pic of auric chloride at 40 Troy ounces per liter (it is still warm off the hotplate).View attachment 1Here is what happens when that same solution was allowed to cool.Harold_V said:My policy was to keep solutions as concentrated as I could. That means you can use smaller vessels (those 4,000 ml beakers aren't cheap) and you have far less waste material to deal with when it comes time to dispose of them.
