Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …

Cast-Iron: Manufacture, Composition, Types, Properties and …

The cast-iron contains about 2 to 4 per cent of carbon. In addition, it contains the various impurities such as manganese, phosphorus, silicon and sulphur. The manganese makes cast-iron brittle and hard. Its amount should therefore be kept below 0.75 per cent or so. The phosphorus increases fluidity of cast-iron.

According to 2003 data, the share of laterites in primary nickel production was reported to be 42%, or ~510 kt Ni [4]. Wood Mackenzie predicted that, by 2022, 72% of the world's nickel production will be from oxide-type nickel ores [6]. Currently, the primary pyrometallurgical process for the treatment of laterites is the RKEF process.

Pig Iron Production – Interstahl

Pig iron usually consists of about 92 percent iron, three to four percent carbon, and varying amounts of silicon (0.5 to 3%), manganese (0.5 to 6%), phosphorous (0.1 to 2%) and traces of sulfur (0.01 to 0.05 percent). Grey pig-iron is produced when the pig-iron is cooled slowly and the carbon settles out as graphite on the raw material.
