· NML has also established an environment friendly recycling process for the recovery of rare earth metals from scrap fluorescent tube (Fig. 3). Under optimized condition with about 99.9% yttrium and ~85% Eu was leached leaving other rare earth metals in the residue. Using solvent extraction technique, selective separation of Eu and Y was obtained.

· Electronics waste is becoming a major global issue. Huge accumulation of e-waste and their recycling through primitive means for extraction of precious metals are real concern in the developing countries due to presence of hazardous materials in e-waste. Recycling of e-waste through appropriate technologies is, however, considered to be a profitable business as the printed circuit boards (PCBs

· native gold from gold-bearing ores or the dissolution of gold metal during the recycling of electronic and precious metal scrap is performed every day using hazardous chemicals such as sodium cyanide or aqua regia. These chemicals represent health and safety risks for workers and a serious threat for the environment. However, even if several
· The results showed that, gold and silver leaching rates can reach 90.87% and 59.82% respectively under the best conditions. 564 Yanhua Zhang et al. / Procedia Environmental Sciences 16 ( 2012 ) 560 – 568 Research by Wu [34] also showed that selectively leaching gold and silver from PCB scrap in acid thiourea solution is possible and

· Description. The cutting mill is a device that uses the interaction between movable knives and fixed knives to break materials into granules by cutting, impacting, squeezing, and other methods. It consists of a feed inlet, crushing chamber, collector, and so on. The materials enter the crushing chamber from the feeding port and then are crushed by the high-speed rotating moving knives and
· Recovery of PGMs (especially rhodium, platinum, and palladium) from different spent manufactured products (like catalytic converters) is considered as an important task as they are rarely found in nature, and they possess high economic value. In this work, the honeycomb of a car catalytic converter was primarily processed by crushing, grinding, and then treating in a hydrogen atmosphere.
· A scrap metal company is a business that buys and sells scrap metal for recycling, manufacturing, and many other applications. Taking apart and separating metals is important to make more money on scrap. With the use of magnets, scrap metal companies can determine ferrous and non-ferrous materials.
· The methods are environmental friendly and take care of the safety of the health of the operators. Disassembly involves the removal of hazardous components such as batteries and other high and low grade including component, part, group of parts or a sub-assembly from a product (partial disassembly) or the separation of a product into all of its component parts (complete disassembly).
· To cater for the rising demand and to avoid negative environmental impacts, the recycling of automotive catalysts is indispensable. Furthermore, the spent catalytic converters, containing an average of approximately 4 g PGMs, represent a high-grade raw material in comparison to primary sources2. Another fundamental motivation for PGM recycling is the limited raw
/ A leader in the self-service market for used car parts, with an inventory of over 22,000 vehicles and more than 24 locations across North America, Kenny U-Pull gives customers the opportunity to pull their replacement parts for a fraction of the manufacturer’s price in a safe, clean and eco-friendly environment.
· In order to develop an environmentally friendly technique for recovery of precious metals from Waste PCBs, a critical comparison of main leaching methods is analyzed based on three-scale analytic hierarchy process (AHP). The results suggest that thiourea leaching and iodide leaching make more possible to replace cyanide leaching.
· Recovery of precious metals from electronic scraps factually is the key to its commercial exploitation by the recycling industry, for profiteering, in the backdrop of the fact that e-scrap contains more than 40 times the concentration of gold content in gold ores found in the US , which is almost one-third the precious metal recovered in e
· The Li-Ion battery scrap from electric vehicles was treated with a hydrometallurgical process. The process comprises leaching, solution purification, Co-Ni-Mn recovery and Li 2 CO 3 precipitation. The batch-wise leaching step revealed extraction rates of Li, Co, Ni, Mn and Al are higher than 95 % at optimum leaching conditions.

· Gold 0.039 Silver 0.156 Palladium 0.009 Copper 18.448 Other metals 9.35 Non-metals 72 Gold, silver, copper, and palladium contributed to more than 91% of the total worth of metals found in PCBs, and thus these four metals were selected for further study. The total value of these metals added up to $24.3 per kg of PCB. II. METAL RECOVERY PROCESS
