Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results.
A liquid–liquid extraction with toluene was used to extract gold gold is the most important material in PCB recovery. hydrometallurgical process for 2011-9-30 HYDROMETALLURGICAL PROCESS FOR EXTRACTION OF PRINTED CIRCUIT BOARDS (PCB) in order to extract gold.
Recycling gold from scrap PC boards (2003) whole PCB board of mixed type from mixed sources will provide around 1-3 USD/lb profit after expenses using AR. Also, don't forget about the other metals out there! Gold isn't everything. Silver, PGMS, tantalum,aluminum, lead and copper all have a ton of potential. Steel scrap can be
this area. For instance, gold, silver, tin, and copper, among other metals, can be recovered by means of the hydrometallurgical treatment of printed circuit boards 2. The E-waste can be treated by thermal and non-thermal methods. The Non-thermal method of treatments uses leaching as one of the main stages. Leaching is the process of extracting
