Terrafame, Finland

Project: Mega Plant Project: Structural Design, Detail Design Construction Support

Terrafame OY appointed Process Plant Technology (PPTech) to design a New Metals Converting Plant (NiSu) at their existing Sotkamo, Finland site. The NiSu consists of 3 processing plants, Cobalt sulphate (CoS), Nickle sulphate (NiS) and Ammonium sulphate (AmS). PPTech appointed Nurizon Consulting (Pty) Ltd. [Nurizon] for the structural steel design of these plants.

The structures are generally separated into different modules for the different mechanical equipment.
The modules were designed separately, to accommodate all the design loads that could be applied within its design life. The modules were also ‘connected’ to the other modules, to enhance structural stability.
The three plants and the respective modules were design in South Africa.

Fabrication and assembly took place in China. Complete assembled modules were sent via ship to Finland for installation and commissioning. The crystalizer units for AmS and Nis were the only units assembled on site. The project commenced in 2019 and commissioning for the plant started in 2021.

Scope of works on the project included:

• Structural Design:
  • General and Project Coordination
  • Structural design according to the Eurocode (structures manufactured in China and erected in Finland).
  • Material Specification (extreme temperatures)
  • Area 1631 Cobalt Sulphate Crystallisation
  • Area 1632 Nickel Sulphate Crystallisation
  • Area 1633 Ammonium Sulphate Crystallisation
• Fabrication Drawings:
  • Area 1631 Cobalt Sulphate Crystallisation
  • Area 1632 Nickel Sulphate Crystallisation
  • Area 1633 Ammonium Sulphate Crystallisation
• Fabrication and Construction Quality Assurance:

Bel Air Bauxite Mine

Project: Bankable Feasibility Study (BFS) 20211

2. Export Facility, encompassing bulk materials handling, port loading and trans-shipping.

Scope of works on the project included:

• Mining - Conventional drill and blast and truck and shovel operations;
• Haulage - Material is transported from the mine pit to the Mine Support Area at the coast;
• Stacking and reclaiming - A 150,000t bulk storage facility;
• Loading - 2.3km causeway/trestle with longitudinal shiploader for charging transhipment barges;
• Transhipment - 15,000t, self-propelled and self off loading barges transport and load Panamax/Capesize vessels at the transhipment zone;
• Mine Support Area;
• Power and water utilities;
• The area houses all administrative complexes, fuel storage, power generation, stores and maintenance.
