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.

Video of emew Lab Cell Test

Posted by Alex Barshai on Dec 9, 2016 3:35:02 PM

Lab tests such as this are an ideal way to demonstrate the recovery capabilities of emew for a variety of electrolytes and feed materials. In most cases, these tests can be done right at your site so you can see the results for yourself.

This particular test is to demonstrate the recovery of copper cathode from a copper sulphate feed solution.  We can test a range of feed materials to recover not only copper, but also silver, nickel, tin and others.  This copper sulphate solution was prepared ahead of time and roughly 3L transferred to the feed tank.

Urban Mining is a New Reality

Posted by Alex Barshai on Aug 29, 2016 10:44:34 AM

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 have 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.
