Challenges in processing nickel laterite ores by flotation ...

2016-6-10 · Thus, the challenge of processing nickel laterite ores still exists. In fact, no physical separation technique (including flotation) has been able to dramatically upgrade nickel in laterite ores (Quast et al., 2015a). The only isolated case with an acceptable nickel upgrading is the result by Denysschen and Wagner (2009). They used dense medium ...

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
