Recycling of Precious Metals from E-scrap
Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...
متن کاملIon Exchange for Recovery of Precious Metals
ith the rapid rise that has occurred in the prices of precious metals during the past few years, recovery of even minute amounts of theseelements has become of greater interest to metal finishers. Although precious metals are recovered easily from concentrated solutions by reduction and precipitation or electrolysis, solutions containing a few parts per million aredifficult to handle by these m...
متن کاملPolymerization Behavior of Resins for Precious Metals
Adhesion promoting monomers — 5(4-vinylbenzyl) -2-thiobarbituric acid (5VS) , 9,10-epithiodecyl methacrylate (EP8MA) , 9,10-epithiodecyl 4-vinylbenzoate (EP8VB) , and 3,4-epithiobutyl 2,2-bis (methacryloyloxymethyl) propionate (EP2BMA) — were added to the MMA liquid of a MMA-PMMA/TBBO resin. Three dental precious metal alloys were butt-jointed together with the MMA-PMMA/TBBO adhesive resin, and...
متن کاملNovel Non-Precious metals for PEMFC
A major impediment to the commercialization of fuel cell technology is the low activity of platinum electrocatalyst used for oxygen reduction. Pt has been alloyed with transition metals like Ni, Co etc, which show higher activity, compared to pure Pt. However, Pt remains, an expensive metal of low abundance, and hence, finding a non-noble-metal alternative is of interest. The overall objective ...
