Can I recover copper from this? Copper recovery from the ground up

Posted by Trevor Bergfeldt on Oct 19, 2017 9:45:13 AM

A question that we hear from Clients every day is "Can I recover (copper - or other metals) from this?"  The material in question can be concentrated wastes, dilute effluents, ores, concentrates, residues, plating baths, bleed streams and so on.  It seems like a very easy and straightforward question to answer, and in some cases that is true.  In other cases, however, the answer is a bit more complicated requiring some additional information.  Let's take a closer look at the good, the bad, and the ugly when it comes to the common question "Can I recover (copper - or other metals) from this?"

Why the world is demanding more cobalt, and why new methods for cobalt recovery are the answer.

Posted by Sara Wollschlaeger on Sep 29, 2017 10:12:21 AM

A review of why new technologies are going to drive the future of cobalt recovery and production.

Background of Cobalt:

Cobalt, the element that is just starting to create a lot of buzz ; from the auto industry to electronics production, the popularity of cobalt is growing rapidly – chiefly for its use in rechargeable batteries. As global demand for cobalt increases, current sources of cobalt may not be sufficient. This imbalance between supply and demand may open doors for novel methods of recovery and recycling of cobalt.

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.

Enhanced methods for nickel recovery from low-grade ores and bleed streams

Posted by Sara Wollschlaeger on Sep 6, 2017 5:09:46 PM

Way back in elementary school when you thought of nickel, the first image that popped into your head was probably that nice shiny 5¢ coin. Even though we hardly carry change purses anymore, nickel is still ever present in our day-to-day lives. From the shiny stainless steel trim on your building, to the knives in your kitchen, nickel is found everywhere.With nickel becoming favoured for use in transport, power generation, cell phones, food preparation, and medical equipment, it leads one to think about where all of this nickel is coming from.

The future of clean energy and its relationship to electrolytic metal powders.

Posted by Sara Wollschlaeger on Aug 28, 2017 10:21:33 AM

I recently learned that metal powders have the potential to be the future of renewable energy sources. This is a relatively new venture, and an area of interest for us, here at emew , since producing metal powders is something we do daily. I wanted to explore the topic of the production of metal powders and explain more about how they are produced to create this renewable fuel source.

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.

Tea & Metal Recovery: An Unlikely Comparison

What do your morning cup of tea and a metal recovery plant have in common? Not a whole lot, is what you would hope! However, this is where you are mistaken. The simple act of steeping tea is, in fact, very similar to the process of leaching in metal recovery.

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.
