Gold corner BGA chips gold recovery | Gold from IC chips | BGA IC gold recovery

Video Description

In today's video I'm going to process BGA IC chips from computer motherboards , tv , and graphic cards. With the great yield of 10 g gold per kg materials. In first place i leached solder with nitric acid , Tin converts to Metastannic acid which i use it later to recover tin from. Then i did wet ashing process using sulfuric acid to open ic chips packages. after that gold bond wires became evident . After that base metals dissolved with nitric acid (copper was dominant metal) afterwards gold wires dissolved using aqua regia. To expel nitric acid i used sulfamic acid then i dropped gold with ferrous sulfate (FeSO4) . gold percipitate washed in hot HCl and melted.
