Pure Copper - Fossil Blu

Once the copper ore has been extracted, it is crushed and ground to liberate the valuable raw copper from the less desirable minerals. From there, the copper is concentrated using a mineral flotation process and smelted to further remove unwanted minerals. The final step involves electrorefining to create the copper we need for our luxury sinks.
