Heating is melting, putting in metal iron category, can replace the copper in it -it is difficult to make a profit using this method. can also use nitric acid to dissolve the metal on the main board first, add metal to add iron — you can get copper and other to add copper — you can get it. It a little bit of the remaining point is attached to the board, or the at the bottom should be gold ... Note! Nitric acid will produce NO2 and NO -toxic and pollute atmosphere!
There seems to be a small amount of gold in the computer! 1 Studies show that the inner parts of a waste mobile phone contain a variety of valuable materials, telling everyone a unknown unknown huge profiteering industry! (Utilizing the electronic garbage of electronic garbage such as waste computers, mobile phone CPU memory, etc.), if you want to know more details, you can search for Liu's gold.

Refine very little, one ton of motherboard can refine 80 to 110 grams of gold
