How to use the hydraulic separation method to recycle the precious metals from the circuit board

As we all know there are many kinds of metals in the computer circuit boards.For example copper,gold,silver,nickel,etc.How to recycle the precious metal from the computer parts is the problem you want to know.Now we will introduce the precious metal recycled from the circuit board by the hydraulic separation method.

Here we use the communication board as the example.

First,put the communication board to the gold deplating cell remove the gild.

And then,use the dismantling machine to separate the raw material to board,chips and the others.

For the board and the other things we use the crusher to crush them to small pieces and use the all-in-one Grinder to get the pieces to powders,and then use the water table to separate the copper,aluminum and tin.In this process,we need use the Magnetic separator to separate the Fe first.

For the chips,Then we use the carbide furnace and grinder made in our factory to get the metal residue,next use the magnetic separator separate the Fe and Ni.And input the dilute sulphuric acid to the residue,we can get the gold and silver residue and copper solution.For the residue,input the Nitric acid get the silver solution and the gold residue input the aqua regia then Reduction to get gold.The main equipment is some glass reactors.
