Extraction of Tin and Copper by Acid Leaching of PCBs
Printed circuit board (PCB) waste is generally dumped as a landfilling or treated pyrometallurg ically, which consumes enormous power, generates hazardous gases and also destroys valuable PCB components. For recycling of the components, they must be separated from the printed circuit boards which is a cumbersome task. For its simplification, the rate of d issolution of solder with acids like Hy...
متن کاملPreparation of nano gold powder from acid leaching tail solution
According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

متن کاملcopper and nickel recovery from electroplating sludge by the process of acid-leaching and electro-depositing
in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...
متن کاملTHE LEACHING OF NEZAMABAD SCHEELITE WITH SULFURIC ACID
A new process for recovering scheelite ores comprises producing a concentrate from the ore, then leaching the concentrate with H_2SO_4 in the presence of H_3PO_4 and Na Cl at atmosphericpressure are discussed. Finely purification of the product will be described. The amounts of dissolution of tungsten in acid depend on the parameters such as time, temperature, type and concentration of acid an...
