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?"

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.

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.

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.
