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.

Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water. Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals. Lenntech provides sustainable complete water treatment solutions for mining industry considering a wide range of technologies and strategies.
