Precious metals recovery from e-waste

Posted by Alex Barshai on Dec 28, 2022 1:08:03 PM

Recovery of precious metals and base metals from electronic waste 

What if I told you that we send hundreds of millions of dollars to landfill every year? If you look around the room you are in right now, you will likely see a multitude of electronic devices. Our reliance on electronic devices in everyday life is growing and rapid technological advances continuously bring updated models onto the market. This means that more devices are being discarded, with more being sent to landfill than ever.

Several base and precious metals make up essential components of electronic devices. The properties of these metals make them ideal for recycling and reuse. Yet, studies have shown that only 15-20% of electronic devices are recycled. This leaves a huge untapped volume of valuable metals that could be sold or reused instead of sitting in landfills.  Effectively recovering metals from these devices could have multiple ecological benefits from reducing the economic burden of electronics recycling to reducing the demand for mining ore.

Silver Refining

What is silver refining? 

Silver refining is typically the final process in the production of high-purity silver suitable for sale in the market.  It is associated with purity and typically needs to meet a minimum of 99.9% purity and in most cases 99.99% purity and in some cases, 99.999% purity depending on the end-use.

Why electrowinning hates iron

Posted by Alex Barshai on Nov 16, 2021 1:33:48 PM

Electrowinning – an introduction

Electrowinning is a process used to recover metals from a solution or an electrolyte, by means of an electrolytic chemical reaction. This occurs when an electric current passes from a cathode that's negatively charged to a positively charged anode through a metal-containing solution. During this process, the electrons reduce the metal ions in the solution to form a solid metal deposition on the cathode. The quality of the metal produced can vary depending on the individual process and may require further processing or refining.

Nickel Powder:  Manhattan's secret ingredient

Posted by Alex Barshai on May 12, 2021 8:36:00 AM

Nickel powders are widely used in industrial applications worldwide, such as rechargeable batteries, manufacturing and powder metallurgy. In some cases, nickel powders are used to add a magnetic feature to a particular material. Nickel can be used in electroplating and coinage industries as well. But there is more to nickel powder, and there is something that you have probably never heard about until now.

When will Artificial Intelligence  take over your factory?

Posted by Alex Barshai on Dec 24, 2020 12:10:00 PM

While Elon Musk compares AI to “summoning the demon” and Bill Gates doesn’t “understand why some people are not concerned” that artificial intelligence slowly but steadily becomes a part of our daily lives.

Our mobile phones are equipped with Siri, Cortana or Google Now that assist us with daily tasks. Self-driven cars are already on our roads, driving thousands of miles with ZERO accidents (or at least they are not the reason for the accidents).

Retailers like Amazon and Target use a self-educating software that can anticipate your needs and offer you the next product to buy even before you know you need it.

How about these online customer support chats? Did you know that most of them are machines hiding behind human names? Many of them have the ability to learn and to adapt to the tone of questions in order to search company websites and present the right information to the customer.

Free Power for Your Electrowinning Plant

Posted by Alex Barshai on May 7, 2019 10:01:27 AM

As the world is advancing towards clean, sustainable energy sources, businesses in traditional resource industries can be faced with a moral dilemma – to sacrifice margins in favour of clean initiatives or continue using conventional equipment and carbon-based energy sources that ensure revenue maximization.

Urban Mining and Metal Recycling

Posted by Alex Barshai on Sep 25, 2018 1:47:15 PM
Did you know that for every million cell phones we recycle, we can recover 35,000 pounds of copper, 772 pounds of silver, 75 pounds of gold and 33 pounds of palladium? By utilizing metal recycling techniques, these recovered metals can be used to solve our continuously depleting resources.
 
In the last decades, we have witnessed a decline in metal concentrations in ores. As a result, mining projects have become more expensive due to the massive amounts of ore that now have to be processed in order to extract pure metal.
 
At the same time, the demand for metals has increased since more and more people in the world are moving to growing cities and want the latest cars, technological gadgets, and computers. Population growth demands housing, infrastructure improvements, public transportation, energy and so on. 
 
So, how do we keep up with the increasing demand for metals while producing countless tons of industrial and electronic waste?
 
The answer is Urban Mining.

The Ultimate Guide to Wastewater Treatment

Posted by Alex Barshai on Aug 21, 2018 11:18:13 AM
Clean, fresh water is a luxury in many countries and is increasingly becoming a valuable commodity.  Our society today is faced with the challenge of harnessing the power of advanced wastewater treatment technologies to preserve our precious water resources.  Not only does this apply to municipal water treatment plants that work around the clock to make sure communities all over the world have access to clean, fresh water, but also in industrial processes to minimize usage and waste.
 
"Presently only 20% of globally produced wastewater receives proper treatment."
- United Nations Educational, Scientific, and Cultural Organization (UNESCO)
 
In the years following the industrial revolution and continuing on into the information age, industries have been challenged to develop new and innovative ways to treat wastewater and bleed streams to encourage recycling and reduce discharge towards the holy grail of so-called 'zero discharge'.  We've come a long way in the latter part of the 20th Century, but there's still work to be done as populations swell, economies grow and everyone strives to improve their quality of life and that of his or her children.

Which metals have held their value over 50 years?

Posted by Alex Barshai on Sep 20, 2017 12:49:13 PM
With technology changing so fast, new raw materials are taking centre stage every day, making it more and more difficult to predict which metals will hold or lose their value in the next 50 years. Recent innovations are making electric cars powered by renewable energy mainstream, fuelling development of novel and more efficient battery technologies.  All of these technological developments depend on resources such as nickel, copper, and cobalt.  Technological trends coupled with geopolitical stability contribute to supply and demand which in turn dictate metal prices.

Correlation between metal abundance, price and recycling.

Posted by Alex Barshai on Aug 1, 2017 10:08:41 AM
After centuries of global mining activity, ore deposits are continually decreasing in mineral grade.  What would have been considered 'tailings' or discard from mines only a century ago, are in many cases considered high grade deposits today.  In order to economically recover metals from these lower grade resources requires more and more earth to be moved, resulting in mining operations becoming larger and larger.
