China’s nickel ore imports doubled in June as supply

2020-7-28  A recovery of supply from New Caledonia from adverse weather also contributed to the sharp increase in China’s nickel ore imports in June. About 246,000 mt of nickel ore and concentrate imports to China last month came from New Caledonia, making the South Pacific Island Nation the second largest supplier of such materials to China.

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.

Reductive Smelting for the Recovery of Nickel in a DC Arc

2013-6-17  The smelting of nickel laterite ores to produce ferronickel [5, 6] essentially involves a trade-off between recovery and grade. The greater the degree of reduction, the greater the recovery of nickel. However, as an increasing quantity of iron (and some more nickel) is reduced to the metallic state, so the nickel grade is diminished.
