nickel ore ore dressing procedure

US3656935A Process for recovering nickel from nickel

This invention provides a process for the treatment of nickel ores whereby the comminuted feed ore is mixed with a halide and an oil and the mixture is maintained at a temperature and for a length of time sufficient to metallize the nickel in the ore by the migration of the nickel from its finely dispersed state in the feed ore to aggregate in the form of globules of iron-nickel alloy.
