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.

10 Questions Answered About Electrowinning and Electrorefining

Posted by Alex Barshai on Apr 17, 2017 9:33:41 AM

 

1. What is electrowinning?

Electrowinning is a process in which metal ions present in an electrically conductive solution are separated using a direct current. This is achieved when a direct current is applied across an anode and cathode that are submerged in an electrically conductive solution causing the metal to deposit on the cathode. We say that metals like these were electrowon.

3 Methods of Nonferrous Metal Recycling

Posted by Alex Barshai on Apr 10, 2017 2:37:54 PM

In a world that is increasingly demanding sustainability, nonferrous metal recycling has become a very important practice. Opting for recycling does not only mean being responsible for the environment and reducing the carbon footprint, it is also a very reasonable business in industries that rely on using non-renewable resources.

Copper Mined vs Copper Refined (by Country)

Posted by Alex Barshai on Dec 21, 2016 11:20:54 AM

Where is copper mined and refined?

Taking a closer look at worldwide copper production statistics we found that some of the biggest copper-producing countries do not necessarily refine the copper at home. The reasons for this depend on various factors. We wanted to find out how much of copper is not actually refined in the same countries from which it was mined.

Video of emew Lab Cell Test

Posted by Alex Barshai on Dec 9, 2016 3:35:02 PM

Lab tests such as this are an ideal way to demonstrate the recovery capabilities of emew for a variety of electrolytes and feed materials. In most cases, these tests can be done right at your site so you can see the results for yourself.

This particular test is to demonstrate the recovery of copper cathode from a copper sulphate feed solution.  We can test a range of feed materials to recover not only copper, but also silver, nickel, tin and others.  This copper sulphate solution was prepared ahead of time and roughly 3L transferred to the feed tank.

emew Power Consumption

Posted by Alex Barshai on Oct 17, 2016 10:33:04 AM
A common question we get here at emewCorporation is:  “What is the power consumption of emew electrowinning technology”.  This is a very important question because power consumption is one of most significant costs involved in electrowinning, regardless of whether it is conventional or emew.

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.
