[VIDEO] emew Advanced Copper Liberators

Posted by Sonny Samra on Mar 28, 2017 12:33:53 PM
Thanks for joining me today for this discussion on emew advanced liberators. Let's start by looking at a simplified copper refining process flow diagram. Copper Concentrate is fed to the smelting process where fire-refined copper is produced. Next onto anode casting, where 99% anode copper is formed followed by electrorefining of copper to produce LME grade copper cathode. But we aren’t done there, the refinery bleed is then sent to copper liberators to control the copper concentration and impurities in the process. It is at this step, where we will focus our time today.

Can I recover copper from this?

Posted by Trevor Bergfeldt on Oct 11, 2016 10:11:32 AM

A question that we hear from Clients every day is "Can I recover {metal} 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 {metal} from this?"

The Ultimate Solution to Low-Grade Mine Waters

Posted by Dora Ip on Sep 26, 2016 4:10:09 PM

As copper continues to be a rich and desired resource for a variety of products such as electrical wire, building infrastructure, electronics and other technology alike, copper process plants have responded by striving to continuously optimize and capture as much copper as possible from their mining processes. 

 

Mining processes have always looked for different ways to optimize their operations such as saving water, using less energy, and minimize on-site waste streams or tailings. Some of these optimizing techniques have included process water recycling from clarified tailings, transfering energy between solutions in heat exchangers, incorporating more gravity controlled flows between processes instead of using pumps, or recovering lost metal from waste streams.

Cracking The Operational Efficiency Code

Posted by Alex Barshai on Sep 13, 2016 9:00:00 AM

When we talk about operational efficiency, what do we really mean? All of us are looking to improve overall corporate performance, but how do we clearly define this?  In order to deliver services or goods in the most cost and time efficient manner, we strive to improve operational efficiency, which is frequently described as a ratio between what we put into the business and what we gain as the output.
