process of mining nickel

Nickel Ore Mining Process. Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods: The most important is the flotation. The magnetic and the gravity separation is usually secondary dressing method

    The extraction from the sulfide ores is a huge process involving froth floatation, smelting and electrolysis. Firstly, the sulfide ores are crushed and ground to liberate nickel containing minerals from the waste material by floatation process where the ore is mixed with certain reagents and disturbed by mechanical devices that produce air bubbles which rise above the mixture and are collected
