Nickel hydroxy-carbonate precipitation in a pellet reactor

Precipitation in pellet reactors was developed primarily for water softening purposes, and then extended in the Netherlands in a research context to heavy metal recovery from stream concentrations varying from 10 to 10 000ppm. The metals include copper, iron, lead, manganese, nickel and zinc. The potential for effluent treatment is broad and covers a range of mining industries metal-containing effluents. The process using carbonate precipitation in a pellet reactor to recover nickel has several advantages over the more commnly used hydroxide sludge process. As a seeded precipitation, no sludge is formed, instead, there is a dense precipitate with good de-watering properties, permitting easy solid-liquid separation.
