What parts of these contain gold?

[Anonymous]

Hi,

I`m new here saw a lot of info here and still learning. If my question is newbie-lame, please be kind and gentle.

Please help me out, what parts (except marked) are gold and/or worth extracting?

Best Regards,

You know, if you have access to tin metal you can test for gold.

A little bit of bleach, and a lil bit of HCL.

Then make some stannous chloride with some tin metal, I follow Laser steves recipe 1 gram of tin metal for every 30 ML of hcl 34%


I think the jack heads have a small amount plating those pins.

most gold on connection fingers, I cut them off Hcl/peroxide for them, square intigrated circuits (flatpacks), pins, and monolithic capacitors for Pd. also I unsolder some of the components for use in electronic projects.
