found in near-surface laterite deposits where the nickel is recovered though open-pit mining methods (differing from underground deposits in other leading producing countries such as Canada and Russia). The marketable nickel produced in Indonesia is in the form of: nickel ore (unprocessed nickel); nickel pig

Mar 29, 2021· Abstract Nickel is mostly extracted from sulfide ores, however, laterite ores account for over 60 pct of all nickel resources in the world, and despite its predominance, there is no well-established process to extract nickel from such ores. Nickel in laterites is hosted in many different compounds such as oxides, hydroxides, and silicates minerals. The sulfation-roasting …

Sep 15, 2020· Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The most important method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods.

Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Read more The Zenith is the professional mining equipments manufacturer in the world, located in China,India, along with ...

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.

In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder. Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel. Smelting processes the concentrate further, creating nickel-rich matte, while impurities are removed as slag.

The making of nickel is a process which involves a number of steps: 1. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.

Process Methods There are two main methods in processing of laterite ores: pyrometallurgy (smelting) and hydrometallurgy (leaching). In pyrometallurgical route, the ore is generally dried first, then calcined in a rotary kiln and then smelted in an electric furnace with carbon. This method is abbreviated as RKEF (rotary kiln electric furnace).

techniques to recover the valuable mineral resources from the ore. The choice of a suitable technique, which is both environmentally sound and economically viable, to process mineral resources very much depends on the type of ore which is mined as well as of the physical conditions linked to the location of the mine site.
