23.01.2020· There are two current industry standards for removing gold from electronic scraps. The first is pyrometallurgy, which burns the gold off using high temperatures. This method is energy intensive, cost prohibitive and releases dangerous gases, like
Urban Mining: The Electronic Waste Gold Mine. Urban Mining The Electronic Waste Gold Mine Millions of dollars worth of gold and silver and sitting in landfills around the world. The precious metals are hidden away in the components that make up our
So, for E-Waste recycling to make a serious offset in reducing the impact of global mining for precious metals like gold, and semi-precious metals like copper, and aluminum, the scale needs to be large enough. At the same time, it also needs to be balanced with efficiency, as well as future scalability.
Up to 50 million tonnes of e-waste is expected to be disposed this year. Recovering metals and rare earth elements from electronics and LED lights will soon become a reality. Text: Jean-Paul Small Photo: RF123 Published: 22 March 2017
Recycled electronic waste is becoming the goldmine of sustainability (Photo: University of the United Nations) The global volume of electronic waste is expected to rise to more than 50 million tons by 2021. In its Global E-waste Monitor 2017, which it published together with the International Telecommunications Union (ITU) and the International Solid Waste Association, the University of the United Nations calculates that 4500 Eiffel Towers could be produced from the annual waste

Keywords: Gold recovery, Pressure oxidation, Ammonium persulfate, Electronic waste (e-waste) 1. Introduction . Recovery of gold from secondary sources has been thoroughly studied in the last few years due to the increase in generation of electronic waste (e-waste). This secondary source contains large quantities of gold and base metals (Cu, Ni, Fe) . The proper metal extraction from e-waste
Recycled electronic waste is becoming the goldmine of sustainability. Around 45 million tons of electronic waste accumulate worldwide every year, with no end in sight. The amount of waste produced in 2016 alone contains raw materials worth 55 billion US dollars. Exploiting these treasures makes both ecological and economic sense. 26 Apr. 2018 Share

23.04.2018· There’s 80 times as much gold in one ton of cellphones as there is in a gold mine, says Federico Magalini, an expert on electronic waste. That means there’s enormous potential for recycling
Recycling of gold from electronics: Cost-effective use through ‘Design for Recycling’ Christian Hagelüken1 and Christopher W Corti2 goldbulletin.org Abstract With over 300 tonnes of gold used in electronics each year, end-of-life electronic equipment offers an important recycling potential for the secondary supply of gold. With gold concentrations reaching 300-350 g/t for mobile phone
If you compare 1 tonne of electronic waste with 1 tonne of gold ore, there is likely to be 100 times as much gold in the e-waste as in the ore. And yet that waste is sitting in landfill, or in millions of cupboards and boxes scattered around homes all over the globe as we tell ourselves 'we'll deal with that soon'.
With over 300 tonnes of gold used in electronics each year, end-of-life electronic equipment offers an important recycling potential for the secondary supply of gold. With gold concentrations reaching 300-350 g/t for mobile phone handsets and 200-250 g/t for computer circuit boards, this “urban mine” is significantly richer than what is available in primary ores.
The mountain of electronic waste rising around the world is a gold mine–literally. Urban deposits of e-waste (discarded computers, phones and other electronics) contain 40 to 50 times the
