Cobalt is produced as a by-product of nickel sulfide ore, which can be mined through both open-pit and underground mining methods. The ore is initially concentrated through froth flotation 65 ...
Nickel is widely used in industrial processes and plays a crucial role in many applications. However, most of the nickel resource mainly exists as nickel oxide in laterite nickel ore with complex composition, resulting in difficulty in upgrading the nickel content using physical separation methods. In this study, high-grade ferronickel concentrates …
To extract nickel from the lateritic ore, conventional roasting methods are used, removing moisture. The nickel oxide is then separated by a reduction furnace, which in turn reduces the chemical-filled water. This …

The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in …
There are two broad categories of mining methods: surface mining and underground mining. Surface mining involves extracting minerals from the earth's surface and is often chosen for mineral or ore deposits that are near the surface. This method is usually more cost-effective for suitable deposits but has a large environmental footprint.
