In this paper the method of hydrometallurgy is adopted to recycle metals from waste printed circuit board PCB . An experimental leaching test was built up to recover precious and hazardous metals from the PCB. Experimental results showed that HCi can be used as metals formation material to separate metal from PCB during the leaching process.
Overview of Waste Minimization Assessment In the working definition used by EPA waste minimization consists of source reduction preventing the generation of waste at its point of origin and recycling.Of the two approaches. source reduction is usually considered preferable to recycling from an environmental perspective.
The FS1012 is capable of measuring a non corrosive gas or liquid medium. The sensor utilizes thermopile sensing which provides an excellent signal to noise ratio and is ideal for applications requiring low power.

Mar 22 2019 Let’s meet at the three most types of Power Supplies. Types 1# Battery. A lot of circuits use a few power. So it can be powered by batteries. This is small and easy to use anywhere. But normally they are lows voltage. Thus. They are the best for low current using. But for heavy load.
Jan 01 2011 The study for the year 2005 by Bastiaan et al. showed that the total supply of e waste in the United States amounted to 6.6 10 6 t 22 kg ca −1 a −1 of which 20 was estimated to be exported to Asia in Japan 3.1 10 6 t 24 kg ca −1 a −1 e waste is produced and in China 0.5 10 6 t. The latter number is believed to increase
Nov 29 2019 With the increasing amount of electronic waste e waste generated globally it is an enormous challenge to recycle printed circuit boards PCBs efficiently and environmentally friendly. However
