hello
i want to get a little experience with the ap method. last night i mixed (15 ml hcl) with (7.5 ml hp 3%) then i put some fingers, pins, simcards, cell phone board( know i should not mix but i want to know what happens for each).
1-after a while the solutin became pale blue then green and i started to see very small foils swiming around and some brown dust dropping down :lol: .
2-then i noticed that the gold is no longer leaching :shock: .
3-so i started to add more 2hcl:1hp(6%). when i add hcl the solution is blue. when i add hp the solution becomes yellow green starts fizzing and then back to blue. and gold stops getting out. i continued adding untill 50 ml hcl:27ml hp
4-i left the solution overnight. in the morning the solution is clear blue, lot of mud on the bottom but still not all the gold is out.
please bear my too many questions :
1-my source of hcl is a detergent brand named flash, its written on the bottle that it contains hydrogen chloride, its like milk in colour and i dont know its concentration :?: . is the results i got satisfactory or should i look for another source?
2-can i leave this solution for any period of time with the gold dissolved till i have more scrap?
3-the first hp added was 6% mixed with same ammount of water to dillute to 3%. should i do that everytime or is it ok to use 6%?
4-one of the boards had a small steel cover and i noticed some brown mud attatched to it. how to clean that?
5-there is some white stuff over the mud. what is that? could it be from the white hcl?
any help is much appreciated. thanks
