Why solution purification process is needed

The presence of impurity metal ions would degrade the product quality and greatly decrease the efficiency of the electrowinning process, increasing the production cost​. In some cases, the existence of impurity metal ions even threatens the production safety.​ Therefore, the impurities remaining after leaching must be purified to certain ranges before electrowinning​

Introducing Metso Outotec Precipitation process

Introducing Metso Outotec Precipitation process

Metso Outotec solution purification and metal recovery technologies have been successfully implemented worldwide​. We provide sulfide precipitation, oxidative precipitation, neutralization, cementation, and reduction technologies​. Our precipitation and recovery technology can be fully integrated into the process. We strive to provide environmentally sustainable precipitation processes with the minimal consumption of additive agents.

Metso Outotec provides processes for the recovery of precious metals such as silver, gold and platinum.
