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?"

5 Amazing Environmental Restorations

Posted by Alex Barshai on Oct 24, 2016 12:28:53 PM
Pollution has become a part of our daily lives. Everywhere we go we are exposed to various types of pollution such as noise, air, energy, light, and others. Pollution can be the result of natural source, as well as human-made. The leading cause of pollution is considered to be motor vehicle emissions. However, it is closely followed by chemical plants, coal-powered power plants, oil refineries, nuclear waste, farms, metal and plastic production, and other heavy industry. Today I wanted to talk about 5 amazing environmental restorations or polluted locations that were efficiently cleaned up by local governments.

Urban Mining is a New Reality

Posted by Alex Barshai on Aug 29, 2016 10:44:34 AM

In the last decades, we have witnessed a decline in metal concentrations in ores. As a result, mining projects have become more expensive due to the massive amounts of ore that now have to be processed in order to extract pure metal. At the same time, the demand for metals have increased since more and more people in the world are moving to growing cities and want the latest cars, technological gadgets, and computers. Population growth demands housing, infrastructure improvements, public transportation, energy and so on. So, how do we keep up with the increasing demand for metals while producing countless tons of industrial and electronic waste? The answer is Urban Mining.

The Ultimate Solution to Acid Mist Challenges

Posted by Alex Barshai on Jun 27, 2016 2:58:19 PM

Many industries generate acid mist as a result of their industrial processes. In most cases the acid mist will be caused by usage of inorganic acids, and in particular sulfuric acid. Sulfuric acid is mostly used in a production of fertilizers, and industries like pulp and paper, iron and steel, mining, refining and wastewater treatment.  Acid mist is formed as a condensation of acid vapour and the extent of the mist will depend on the industry, process and solution itself.

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.

A 5 Step Recipe to Metal Recycling | Electrometals

Posted by Dora Ip on May 3, 2016 10:55:31 AM

As our lives become progressively advanced with the newest technological developments and electronics, so do our desires to keep up with the latest piece of technology.


The price of purchasing the newest gadget also considers the increasingly harder-to-mine metals required to manufacture this technology.


With growing consumer and production demands, the global grades of essential metals are also proportionally decreasing, making it harder than ever to keep up with the world demand for refined metals.

Metal Recycling in Industrial Applications

Posted by Dora Ip on Apr 26, 2016 9:30:00 AM
Did you know that for every million cell phones we recycle, we can recover 35,000 pounds of copper, 772 pounds of silver, 75 pounds of gold and 33 pounds of palladium? By utilizing metal recycling techniques, these recovered metals can be used to solve our continuously depleting resources.

What is Metal Recycling really? 

Presently there has been a greater push for urban metal recycling and instead of the traditional metal sources and mine sites that have been geologically "rich" for mining, more focus has been placed on metal waste and waste solutions being thrown out by consumers, businesses, or industries alike. Simply by recycling metals from "urban mines", the overall metal economy becomes a circular metal economy versus the traditional cradle-to-grave system.
