Abstract
The possibility of using electrolysis with carbon-graphite flow electrodes of fibrous carbon materials for recovery of gold and silver from solutions formed at various stages of jewellery manufacturing is considered. It is demonstrated that electrolysis with carbon fibrous electrodes ensures high (more than 99%) degree of gold and silver extraction: 1) from sulphuric acid
