Copper-Nickel ores - Danafloat - Home

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.

Aleksander Burba - Wikipedia

Copper-nickel separation smelting. In 1941–1942 he was one of the leading development engineers of technology of separation smelting (so named top-and-bottom smelting), which resulted in a simultaneous production of both copper and nickel in the water-jacket furnaces at the Mednogorsk Copper-Sulfur Plant. Such process was to replace the previously used one, when only copper was .

Nickel Metal: It's Properties, History, Production & Uses

The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor-intensive and expensive to extract. However, the separation process for these ores is much cheaper than for the lateritic variety, such as ...

The nickel and ammonia solution contains 2:2 ratio of nickel to ammonia (molar), which is roughly 50 grams nickel per liter of solution. The nickel-ammonia solution is then reduced with hydrogen in autoclaves, adding a a small amount of ferrous ammonium sulphate. This solution is heated to 250 deg F at 350 PSI, in a hydrogen atmosphere.
