“Recycle based on Excellent Analysis and Recovery & Purification Technology"
It is Recycle System for securing the insufficaient precious metal resources, and pro-vides Total Service for precious metal recovery and purification based on the reilability and technical power.
With prominent Recovery & Purification technology and high-reliability analysis technology, It is possible to refine and recycle after recovring the eletrnics compo-nents scrap of petrochemical/car wasted catalyst such as mobile phone, and PDP as well as any scrap which including metal of Au, Ag, Pt, Rh, Pd and Ru
In petrochemistry and chemical process, it is used various types of
catalyst to get the required product in production process, and
some of them contain precious metal of platinum or palladium. It
must be regularly replaced for smooth production, and in that time
wasted catalyst is generated.
Pipe Pellet Type catalyst used in Ethylene Glycol
(EG) reaction process, and it includes silver (Ag)
replaced by 3~4 years.
Silver Paste Scrap used in PDP electrode.
It is generated a Silver Scrap of Scrap Etching
solution and Filter which is from the remainders of
product cases (packages) and electrode printing.
It contains Precious Metal of Au, Ag, Pt, Pl, Rd, and Ru in mobile phone case, electri
cal board, ornament, catalyst, and other electronics.
|① Scrap||Collect each kind of Precious Metal Scrap|
|② Pretreatment||Slimming homogenization through smashing and heat treatment|
|③ Sampling||Sampling for analysis to represent the whole Scrap
(Gather 3 times for the same sample: for two times analysis by both company and stocking)
|④ Analysis/Estimation||Analysis for the contents of precious metal, impurities, and moisture|
|⑤ Analysis Discussion||Contracting the contract after confirming both analysis results|
|⑥Precious Metal Extract||Precious Metal extract from Scarp by melting and chemical treatment|
|⑦ Precious Metal Recovery||1st recovery of precious metal with low purity from extracted Precious Metal solution|
|⑧ Purification||Purification the 1st recovery of precious metal to be 99.99% or more purity by physical, chemical, and electrical methods.|
|⑨Precious Metal Resourcing||Processing the refined Precious Metal to be the shape of Ingot, Granule, and Powder.|
It is classified as below by its recovery pathway and feature that the Recycling method of Precious Metal, and we get highly purified precious metal by selecting the best proper method for the condition of the objects.
|Classification||Dry Recovery||Metal Substitution||Chemical Reduction||Electrochemical

|Short recovery L/T
|Very high purity|
|Demerit||Difficult to remove the
High energy cost.
|Low Ag purity.
Additional purification process is
Need environmental cost.
|Impossible to recover
with high purity.
Electrochemical purification method is divided into two methods of ElectroPurification and Electrowinning method, and ElectroPurification is used in general.
