excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore.
