Precious metal refining systems

The precious metal recovery&refining plant is used to extract precious metals such as gold,silver,palladium and platinum from electronic waste precious metal chip components and anode slime,and the purity of extracted precious metals can reach 99.99%.Its raw materials mainly come from waste mobile phone circuit board,computer CPU,motherboard ,VCD,CD,TV,game machine,fax machine,telephone,mobile communication and other household appliances;

Technical Parameter:

Model	Capacity(Kg/Day)	Total Power(Kw  )	Rate Purity	Purity
GM-100	100-200	20	≥99%	≥99%
GM-200	200-300	30	≥99%	≥99%

There are alsoleftover materials from electroplating factory,electronic component factory,printing factory,photosensitive materials factory and electronic factory.

Production Process:

 

 

1.Dispensing the gold stripping solution;

2.Put the surface plated materials into liquid,then the surface gold dissolved in the gold stripping solutions,no other metal like lead,nickel,iron,or any other metal be dissolved in the solution.(our patent product);

3.Filtering to remove the impurity; 

4.Reduction:Add the reduction powder to the solutions,the gold will be extracted and turn into black powder,Get the black powder settle down,then finally we get the crude gold powder.

Features

1.After processing waste water emissions remain the same;

2.The recycle rate of gold,sliver,platinum,palladium can get more than 97-99%;

3.The purity of the precious metal can get 99.99%;

4.Full Automatic,saving the labor cost;

5.The process is short,use the hydro metallurgical without cyanogens technology,reduce pollution to the environment.
