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?"

Metal Finishing: What's Electrowinning got to do with it?

Posted by Dora Ip on May 18, 2016 10:00:00 AM

What is Metal Finishing?

Metal finishing is a type of surface finishing that can be defined as the deposition of a metallic coating onto a product either to enhance performance, function or aesthetic qualities while providing overall added value. While it's not obvious on a daily basis, many objects have been subjected to metal finishing for use in our normal lives. These include parts in a car, aircraft, fencing, medical and dental devices, industrial machinery or even beautiful pieces of art. The term finishing is based on the fact that it's normally the last step of the manufacturing process (save for any heat treatment).

The Ultimate Guide to Industrial Wastewater Treatment

Posted by Dora Ip on May 10, 2016 2:48:33 PM

Clean, fresh water is a luxury in many countries and is increasingly becoming a valuable commodity.  Our society today is faced with the challenge of harnessing the power of advanced wastewater treatment technologies to preserve our precious water resources.  Not only does this apply to municipal water treatment plants that work around the clock to make sure communities all over the world have access to clean, fresh water, but also in industrial processes to minimize usage and waste.

 

Many industrial processes in the automotive, textile, manufacturing, mining, oil & gas, and jewelry sectors are designed to reuse process water as much as possible.  Even the most cleverly designed processes however require a 'bleed' or outlet to prevent the build up of impurities that can affect the quality of the finished product if not properly dealt with.  

 

Presently only 20% of globally produced wastewater receives proper treatment.
