It is at the Yepleu area that Sama made the first discovery of nickel-copper sulphide mineralization at surface in West Africa. The Yepleu area is located 18 kilometers southwest of the Samapleu nickel-copper deposit. The Samapleu-Yepleu mineralization is similar to conduit‐hosted nickel deposits found elsewhere.

Blackstone notches up more Vietnam nickel hits | .

Blackstone is chasing massive sulphide veins at Ban Chang that are similar to its nearby Ban Phuc deposit. Previous owners at Ban Phuc produced 20,700t of nickel, 10,100t of copper and 67,000t of cobalt from 975,000t of ore grading an average of 2.4 per cent nickel and one per cent copper between 2013 and 2016. The average vein width was 1.3m.

Copper-Nickel ores

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C may improve the ...
