Sustainable metal recovery and water treatment. 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. The gypsum and metal hydroxides which are produced in this process complicate reuse of the valuable metals, with large quantities of sludge and increasing costs as a result.
