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).

What pops into your mind when you see the word, "liberation"?

---

The word liberation comes from the latin word, liberatus, which literally means "to set free" or "to deliver", and can easily apply to myriad of different topics from politics and religion to science and industry.

Particularly in the copper industry, the word liberation applies to the act of freeing copper specifically from refinery bleed electrolyte. The process that starts with mining and carries on through smelting and electrorefining is complex with many process operations.  Let's take a closer look at the story of 'liberating copper'.  

On average, mined ore contains about 1% copper and in order to recover this copper from the rock it requires several physical and chemical processing and refining steps in order to produce market ready copper metal.

Electrometals would like to congratulate Bosch Australia for winning the Premier's Sustainability Award for Environmental Protection using emew technology to recover copper from industrial wastewater!
