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.

Metal recovery plants - monitoring, optimization, and fault prevention.

Posted by Alex Barshai on Jun 27, 2017 11:37:45 AM

With much of the world rapidly progressing towards everything IoT, machine learning, and smart algorithms, many resource-based companies in industries such as mining, refining, and other industrial areas are still dragging their feet. The need is there, the technology is available – so what prevents some companies from jumping on the data analytics train?

Let’s look at some operational parameters that can be affected by lack of action and how technology can benefit the metal recovery industry.

Five Things You Should Know About Metal Powder Production

Posted by Alex Barshai on Jun 20, 2017 4:20:28 PM

In electroplating, powders can be a very bad thing, but sometimes bad can be good. We are going to discuss doing a ‘bad thing’, but doing it consistently well.

Electrocoagulation 101

Posted by Alex Barshai on Jun 7, 2017 11:57:07 AM

Electrocoagulation (EC) is an electrolytic process that is used mostly for wastewater and industrial process water treatment. Due to its unique ability to remove contaminants such as emulsified oils, suspended solids and dissolved metals, electrocoagulation has become one of the fastest growing technologies in this area. There are various devices and systems that comprise the basic principle of electrocoagulation which I would like to explain in this article.

10 Questions Answered About Electrowinning and Electrorefining

Posted by Alex Barshai on Apr 17, 2017 9:33:41 AM

1. What is electrowinning?

Electrowinning is a process in which metal ions present in an electrically conductive solution are separated using a direct current. This is achieved when a direct current is applied across an anode and cathode that are submerged in an electrically conductive solution causing the metal to deposit on the cathode. We say that metals like these were electrowon.

3 Methods of Nonferrous Metal Recycling

Posted by Alex Barshai on Apr 10, 2017 2:37:54 PM

In a world which is increasingly demanding sustainability, nonferrous metal recycling has become a very important practice. Opting for recycling does not only mean being responsible towards the environment and reducing the carbon footprint, it is also a very reasonable business in industries that rely on using non-renewable resources.
