Alloy selection for service in chlorine ...
nickel alloys, and requires Alloy C276 or titanium. Carbon steel resists dry chlorine and traces of moisture merely leave a film of ferric chloride. Chlorine is a powerful oxidant, however, and steel can ignite in dry chlorine, depending upon form and temperature. For example, steel wool or wire can ignite at as low as 50 °C (122 °F). Steel compressors are not specified above 110°C (230 ...

Nickel ore
· Nickel ore a liquefaction risk. 21 June 2018. Liquefaction risks of nickel ore cargoes from Indonesia and the Philippines have been a longstanding prominent issue which require constant vigilance and review by shipowners and charterers. Since 2010, the liquefaction of nickel ore cargoes has caused the capsize of seven vessels.
Separation technology in mining | Mineral ore processing
Separation technology from Flottweg: the right solution for every extraction process in the mining industry. Flottweg decanters are virtuosos in the mining industry above all when it comes to processing ore and minerals. Ore processing is highly important, particularly in the production of precious metals and nonprecious metals.
Processing Nickel Ores
The nickel ore is sent to the nickel refinery, where a complex set of reactions is carried out. These include leaching in autoclaves using ammonia, heated to around 200 deg F at elevated pressures of 100150 PSI. The appliion of heat and pressure dramatically speeds up the chemical reaction and produces the nickel much faster than leaching at room temperature and atmospheric pressure. There ...
