Introduction to Process Water Recycling and Treatment in Mineral Processing

Presented by

Saara Hagnäs and Piia Suvio D.Eng., Product Manager and Director Water Treatment Solutions, Industrial Water Treatment

About this talk

Introducing a series of webinars on tailings dewatering, the third webinar will introduce water recycling and treatment in mineral processing. Each webinar will cover the topic from equipment to plant, taking a holistic view of the issues that enable and constrain the technology. In water recycling and treatment, we review the basics of water in mineral processing, and then expand the concept to water recycling and treatment in mineral processing plants. Water recycling in mineral processing plant can significantly increase the amount of water available for processing. Recycling of water leads to increase in constituents present in water, leading to accumulation of impurities that can impact the recovery of metal within the flotation and reverse flotation processes. Review on testing of the impact of certain impurities has been carried out and results will be presented. At the end of the webinar we will outline recommendations for process water treatment that can improve the recovery.
