Experts who deal with copper and nickel will know that copper and nickel are two closely related metals. Copper often can be found in the nickel-bearing ore, while nickel is always present in the copper-bearing ore. However, industries will always separate the two metals other than end up with an alloy of the two in the process of smelting and refining. In the last several decades, different methods have been found out to separate the two metals, which are sort of expensive in some degree. And in this text, Amisy, the expert of copper recycling machine, will introduce an effective and relatively inexpensive way to separate copper and nickel.
At the beginning, you need to prepare an ore composed of copper and nickel. Then, find some equipment to crush and grind the ore, and separate out the worthless material by the method of flotation, which will leave you a concentrate that typically composed by 2%-10% nickel and 5%-20% copper .
Next, you need to smelt the concentrate in a reverberating furnace or some other equipment. And the smelted material is defined as matte by metallurgists. Then wait until the matte cools down, during which time, particles of copper sulfide, nickel sulfide, and a metallic fraction will be formed.
In the end, you can recover the metals by means of crushing, grinding, flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel. Acid leaching can dissolve and separate out copper while oxidizing the matte can be used to leach our nickel.
Of course, with the progress of technology, more and more effective methods will be used to separate copper and nickel. Although Amisy is just a manufacturer of copper recycling machine-copper cable granulator and wire striper machine, we are always willing to learn. It can be said without exaggeration that Amisy is an innovative enterprise in the copper recycling business, and it will be a wise choice to cooperate with us.
