First of all, we are dealing with dangerous acids and toxic solutions that need a safe approach and responsible waste handling. Study and learn to work according safe practices. Know the risks and have neutralizing liquid nearby.
Use nitrile disposable gloves and safety glasses. Always when working with chemicals.
Use closed reaction vessels with scrubber flasks and preferably a fume hood. Or work outside in a clear area. Prevent gases from escaping to unwanted places like your work area.
There are a lot of different components in cell phones.
First learn and study a couple of things before you start buying acids and throwing in stuff thats hard to separate later on.
Scrap the different parts. Separate the ic's from the plated pins and cicuit boards and other parts, use a magnet to take out iron.
Take off all metal pieces, watch youtube for clues how to scrap and where to find valuables.
Dont burn it all at once. There are better ways and less poluting. Different components need different processes.
The most important thing to understand for beginners is solder (tin) is your enemy. Get rid of it in some HCL if mechanical separation is not possible. Search 'tin paste' to understand what other new guys ran into.
Its a lot of fun if you are interested. But recovering gold and other precious metals from phones and other e-waste is not easy. Some parts are some require a larger understanding of the chemistry behind it then others.
To do it professionally on a big scale is another thing. Especially if your employing people.
Lots of information here. Learn to use the search function and narrow down your search results.
A great way to start to learn gold recovery and refining is with close cut ram fingers and the Acid peroxide process.
