“…In particular, we avoided the use of toxic reagents or strong acid in high concentrations, particularly those which produce toxic fumes such as concentrated H 2 SO 4 or HNO 3 , commonly used for copper and base metals leaching [2][3][4]. 1 In the case of reaction (A), the diiodine Me 2 dazdt·2I 2 adduct can be used in place of the mixture of the two reagents.…”

“…A variety of hydrometallurgical procedures has been proposed in the past by several authors for the dissolution/extraction of Noble-Metals (NMs) [2][3][4]. The most significant approaches are generally based on the following two processes: (1) cyanidation based on the use of cyanide salts into basic media with subsequent adsorption on activated carbon and reduction of the complex by electro-winning.…”

Abstract:A process based on the lixiviant properties of organic mixtures of dihalogen/S,S-ligands, N,N′-dimethylperhydrodiazepine-2,3-dithione (Me 2 dazdt) and tetraalkylthiuramdisulphide (Et 4 TDS) in the presence of diiodine, for gold recovery from the non-ferrous metal fraction of real shredded waste electric and electronic equipment (WEEE), is presented here. Selective dissolution of metals is achieved through a sequence of three steps where the oxidation of different kinds of metals is achieved by using: (1) refluxing water solutions of HCl 1:5 under Ar atmosphere (Sn, Zn, etc.); (2) water solutions of NH 3 /(NH 4 ) 2 SO 4 mixtures in the presence of H 2 O 2 on the resting sample (Cu, Ag); and (3) acetone solutions of Me 2 dazdt or Et 4 TDS/ I 2 mixtures on the final residue (Au). Each step is followed by a further treatment for: (1) metal recovery, in the case of Au, Cu, Ag; and (2) inertization, in the case of heavy metals. As a whole, the process is very promising for effective recovery of gold and other valuable noble-metals and for using non harmful reagents in mild conditions.

“…However, most of rare metals cannot be recovered by conventional pyrometallurgical processes 10 . Hydrometallurgical methods have been proposed to replace pyrometallurgical methods because they are considered to offer more eco-friendly and efficient means of recovering the metallic elements including rare metals 11,12 . In all these methods, mechanical pre-treatment processes such as comminution are needed to liberate the metallic components, allowing separation and facilitating the efficient recovery of metals in the subsequent metallurgical processes 13,14 .…”

Recycling of printed circuit boards (PCBs) is an important subject not only from the treatment of waste but also from the recovery of valuable materials including rare metals. We have tried a special and selective grinding such as parts detachment from the board using drum typed agitation mill to concentrate a part of "rare metals". The objective of this study is revealing the mechanism of parts detachment process from PCBs. A simulant PCBs on which nine capacitors were solder-mounted were used for the communition test using the agitation mill. Effects of rotation speed and the number of boards for parts detachment or board breakage were investigated. Both of parts detachment rate and board breakage rate were increased as rotation speed increased. On the other hand, as the number of boards increased, parts detachment rate was increased while board breakage rate was slightly increased.DEM simulation with and without particle breakage model was conducted. DEM simulation with spherical particle model (without particle breakage model) showed that board breakage was strongly affected by collision of PCBs to the wall in the normal direction while parts detachment was affected by both of collision of PCBs to the wall in the tangential direction and interaction between PCBs. To investigate the mechanism of parts detachment process more directly, DEM simulation with particle breakage model was also conducted. Simulation results obtained from DEM with particle breakage model corresponded to these experimental trends successfully.
