Pilbara Minerals
Minerals Processing
Marble Bar, Western Australia

Pilbara Minerals is an Australian lithium-tantalum producer listed on the Australian Securities Exchange (ASX) and considered within the top 200 companies in Australia. Through the development of its Pilgangoora Lithium-Tantalum Project (Pilgangoora), Pilbara Minerals is one of the biggest lithium raw materials producers.

Primero has become a delivery partner of choice for Pilbara Minerals and has been actively involved in all aspects of the development and operation of the Pilgangooora Project.


Recognised by Pilbara Minerals as one of the only engineering firms in Western Australia with direct lithium plant construction, commissioning, and operation experience; Primero was initially engaged to undertake the FEED of the DMS circuit at Pilgangoora. Primero’s scope of work quickly grew to include the installation of the ball mill, supply, and installation of the HMS, the installation of the high-pressure grinding rollers (HPGR), and various site conveyors.

A key component of Primero’s scope included the design and implementation of the control system throughout the plant. After the achievement of commercial production in April 2019, Primero has provided ongoing operational and project support with the embedment of key personnel into the Pilbara Minerals team.


Primero has safely delivered large-scale construction projects across the resources, oil & gas and infrastructure sectors. Our ability to effectively deliver any type of project through a variety of construction methodologies is underpinned by our core beliefs: working smarter, upholding promises and taking ownership. Primero’s construction team has many years of experience in all aspects of civil, structural, mechanical, piping, electrical and instrumentation construction activities.


Primero’s services were retained beyond wet commissioning to achieve rapid productivity improvements throughout the process plant in three key areas:

  1. Asset Management: Consultancy services to improve operating practices.
  2. Engineering: Design, procurement and documentation change management.
  3. Execution: Onsite mod squad to implement rapid changes.

Improvement opportunities are jointly identified and passed to Primero for estimating, engineering, procurement and execution; releasing the Pilbara Minerals’ operation and maintenance team to concentrate on day-to-day production.
