The third hydrogen sulphide production line goes into production 1.8.2018

Terrafame has commissioned a new hydrogen sulphide production line in its plant area in Sotkamo, Finland. While the new line will increase the production capacity of the metals production plant, it will simultaneously improve the operational reliability of the production process of the metals production plant.

The planning work of the third hydrogen sulphide plant and related lines started in autumn 2016, and construction work was initiated in early summer 2017. Around 40 companies across Finland have participated in the project.

Terrafame utilises hydrogen sulphide in the extraction of metals from the process solution. Two hydrogen sulphide plants, built between 2008 and 2009, have already been in operation at the company’s industrial site, and they will continue to be operated.
