The formula for success – for Eco-Tec’s Copper Electrolyte Puriﬁcation Systems – has been to deliver a simple, economical system for purifying acid bleed streams. Now, this technology is being applied further by Eco-Tec to address additional contaminants involved in
the production of high purity copper.
These Electrolyte Puriﬁcation Systems are based on the world-leading Acid Puriﬁcation Unit (APU®) design, which has been installed in close to 400 operations around the globe – recovering many diﬀerent acids in many diﬀerent industries, including the treatment of hydromet streams.
For electroreﬁning and electrowinning operations, certain contaminants are known to drive up a number of costs while hindering purity levels and process eﬃciency. The
problematic contaminants, which can diﬀer depending
upon the composition of the feedstock, are:
For years, electroreﬁning and electrowining operations wishing to eﬃciently produce high-purity copper have relied on Eco-Tec’s Copper Electrolyte Puriﬁcation Systems to continually remove nickel and iron impurities from copper electrolyte bleed streams. Now, however, these operations can incorporate solutions that speciﬁcally
cater to each contaminant problem.
The new Electrolyte Puriﬁcation Systems include:
• NiRS- Nickel Removal System
• BARS- Bismuth/Antimony Removal System
• ARS- Arsenic Removal System
• SeRS – Selenium Removal System
• TeRS- Tellurium Removal System.
