Carrying nickel ore: The world's most dangerous cargo
Apr 07, 2017Nickel ore is a cargo that may liquefy if the Moisture Content (MC) exceeds the Transportable Moisture Limit (TML). The point at which the cargo can begin to act like a liquid is when the Flow Moisture Point (FMP) is reached: a theoretical figure set at 90% of the FMP to create a 10% safety margin.

nickel processing
One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.
