That's better. Easier to understand you too.
If all you have is 10 kilos of old cellphone boards then I would say sell it on eBay, but if you want to learn to recover and refine gold it's a good start. It isn't the best type of scrap to learn refining on, we usually recommend gold plated fingers for that.
Use the search function, there are a lot of threads on recovering gold from cellphone boards.
If it is worth your time, only you can decide. I'm saving it for a slow day or retirement, whatever comes first. Only 15 years left until retirement, so it will probably come first! :mrgreen:
