The metal and mining industry is increasingly aware of the opportunities to recover valuable resources from process and bleed streams. This combines creating revenues with environmental sustainability. The traditional method of removing dissolved metals and sulphate from aqueous process- and waste streams in the metal and mining industry is by neutralization with an alkaline agent like lime.

Mining of nickel began in 1875 in the Houaílou and Canala regions. By the end of 1981, just over a century of mining had yielded 11 0 million tonnes of nickel ore, equivalent to 2.5 million tonnes of pure nickel. About half of the nickel ore production has been smelted in New Caledonia, the other half being exported, mainly to Japan.
