Silver Recovery from Scrap and Low-Grade Residue

Posted by Sara Wollschlaeger on Dec 19, 2017 10:19:40 AM
Due to the increase in electric and electronic equipment (EEEs), high-purity silver continues to be in high demand. For the past 4 years, silver demand has exceeded silver mining production, but the global supply has nearly met the demand each and every year – thanks to silver recovery and silver refining. Silver recycling will also be critical to meet future demand, especially as we see the general demand of metals increase across the globe, in relation with technological growth. High-purity silver can be produced from silver refining and silver recycling by utilizing a series methods and processes, such as silver electrowinning and electrorefining. I’d like to delve into how these processes are carried out, and the outlook for silver production.

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?"

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.

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.

The 411 on Nickel Powder

Posted by Alex Barshai on Aug 3, 2016 12:19:05 PM

Nickel and Nickel Powders

Nickel is a lustrous silvery-white metal with a tint of gold. While nickel is the 5 th most common element on earth, most of it is inaccessible in the Earth’s core. Nickel and nickel powder are widely used in hundreds of thousands of products, in most cases as alloys with other metals, such as chromium. Nickel alloys are used to create stainless steel and heat-resisting steel and provide some great anti-corrosion capabilities.
