The Recycling of Cobalt from Alloy Scrap, Spent Batteries or Catalysts and Metallurgical Residues — n in the near future for the production of clean energy..Because of the uncertainty surrounding the supply of primary cobalt from Central Africa, it is more and more imperative to improve the recycling of cobalt from its various uses..This paper reviews methods to recycle cobalt from the scraps of v

Extraction of Nickel, Cobalt and Iron from Laterite Ores by Mixed Chloride Leach Processdeposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte. High iron (> 35 % Fe) limonitic ores can be treated by

Reductive Leaching of Limonitic Laterites Using Ferrous Sulphateum sulphate media using ferrous sulphate as reductant. Different parameters were examined, such as total ammonia concentration, temperature and ferrous sulphate concentration. At 80°C, 130 g/l of total ammonia, 2.73 g FeSO4/ g ore and pH 8.2, nickel extraction was 64 % while 20 % of cobalt remained

Characteristics of Nickel Laterite Crushed Ore Agglomerates It is well known that proper agglomeration can prevent solution channeling and ponding, improve percolation within the heap and increase metal recovery rates. However, not much is published regarding nickel laterite agglomeration behavior. Agglomerate size distribution and bed permeability are impo

Acid Mist Abatement in Base Metal Electrowinningonomic pressures. Enablers include evolving designs and improved materials of construction. Cellhouse designs now typically include addition of surface tension modifying agents, cell hoods, and anode bags or anode skirts to reduce acid mist production. Automation is increasingly being considered to
