Powder Leach Nickel Sulphate

Key Facts

• Number of staff at peak: 40
• Volume of concrete: 2,000m³
• Volume of earthwork: 2,000m³
• Tonnes of REO: 500

Project Overview

• The Powder Leach Nickel Sulphate Project involves the development of a plant that will convert nickel metal powder into a nominal 100,000 dry tpa of high purity nickel sulphate-hexahydrate crystal product.
• The Site is at the Kwinana Nickel Refinery (KNR) in Western Australia.

Project Scope of Works 

Construction consists of:

• Detailed earthworks – excavate, trim and finish all earthworks by grading and compacting the ground around concrete structures, saw cut the road asphalt surface and remove kerbing falling, remove all waste materials etc
• Concrete works – raft foundation / isolated footings, blinding, slabs on grade, pedestals, bund walls, drainage sumps, gratings, cast-in holding down bolts, cast-in grout tubes and cast-in conduits for the following areas:
  
  • Powder Leaching (WBS 3810)
  • Nickel Powder Transfer (WBS 3812)
  • Aeration and Filtration (WBS 3830)
  • Nickel Hydroxide (WBS 3840)
  • Crystalliser (WBS 3850)
  • Product Bagging and Storage (WBS 3860)
  • Utilities & Reagents (WBS 3870)
  • Piping and Electrical Services Rack (WBS 3880)
  • HV & LV sub-stations and transformer compounds (WBS 3885)
