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.

Nickel and Nickel Powders

Nickel is a lustrous silvery-white metal with a tint of gold. While nickel is the 5 th most common element on earth, most of it is inaccessible in the Earth’s core. Nickel and nickel powder are widely used in hundreds of thousands of products, in most cases as alloys with other metals, such as chromium. Nickel alloys are used to create stainless steel and heat-resisting steel and provide some great anti-corrosion capabilities.
