Nickel & Cobalt Electrowinning

Under conditions similar to those for the nickel electrowinning, cobalt was electrowon with lower electrical energy consumption rates and higher current efficiencies than nickel, so that recommended pilot plant parameters for a 5-g/l extraction per pass were 50° to 65° C with a cobalt .

A New Process for Cobalt Nickel ... - Teck Resources

Historically, a number of processes have been used commercially for cobalt separation from nickel in liquor, but currently the favoured process is the selective solvent extraction of cobalt away from nickel, using phosphinic acid derivatives, e.g. Cyanex 272.

Sep 29, 2017 · Copper-cobalt ores are primarily found in Zambia and the DRC, where the cobalt is recovered from copper flotation concentrates, using a roast-leach-electrowin (RLE) process. The ore is roasted (for sulfides), followed by a sulfuric acid atmospheric leach, and direct electrowinning of copper.

Cobalt processing | Britannica

Cobalt processing. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally. The best-known is cobalt-60, which has a half-life of 5.3 years and is used in medicine and industry.

The Food Irradiation Process

The Food irradiation process. The radionuclide used almost always for the irradiation of food by gamma rays is cobalt-60. It is produced by neutron bombardment in a nuclear reactor of the metal cobalt-59, then doubly encapsulated in stainless steel "pencils" to prevent any leakage during its use in a radiation plant.
