Nickel
Nickel can be found in complex ores containing other metals, such as copper, cobalt, precious metals, etc.
Nickel is used in the production of stainless steel, alloy, and batteries and is also used as a plating material.
Market Needs
In the high-pressure acid leaching process (HPAL), where acid is used to leach nickel from ores, the remaining acid must be treated.
Moreover, metal impurities in complex ores must be removed in order to achieve high purity nickel.
Solutions
Limestone
- Neutralize nickel, the remaining acid and waste stream
- Help remove heavy metals from process liquor
Hydrated Lime
- Help precipitate heavy metals in the waste stream for disposal
