2 Exploitation of nickel ore, iron ore and Ruby chromium

摘要

Chromium is removed from the nickel red ore by measuring the particles of the ore, and a part of the fine product is provided according to the particles of the ore, in which all chromium is basically soluble acid, and then soluble chromium is leached from it.The ejections of fine metals, nickel and other metals produced by high temperature leaching in hydrogen sulfide solution produce very low chromium iron ore residue suitable for iron recovery.
