Rincón Project — lithium carbonate (Rio Tinto)
The largest RIGI commitment in Argentine lithium: Rio Tinto is building a 53,000 tpa plant at the Salar de Rincón using DLE (nanofiltration). The first large-scale lithium project by a global diversified major in the country.

- The works, milestone by milestone — We have not built this project’s timeline. Dated milestones with their source close it.
- Who already has a contract — We have not surveyed this project’s awards. A published contract with its source closes them.
How to supply itwhere to register, what they ask for and what they will buy
What it will need and has no supplier for yet
Brine drilling and pumping + pond piping
highThe DLE operation demands well fields and continuous brine pumping at industrial scale.
Export logistics along the Salta-to-Pacific-ports corridor
highCarbonate exported to Asia leaves through Andean passes: high-altitude heavy transport and cargo consolidation are a structural bottleneck of the Puna.
- How to become a supplier — We have not built this project’s entry map. It is our gap, not a prohibition: it closes by opening the provincial register and the operator’s single window.
- What it will buy, and when — We have not built this project’s phase → demand chain: its schedule still has to be crossed with the province’s catalogue of markets and trades.

What it leaves in Saltajobs, works, taxes, promises and the outlook
- The works that stay behind — We have not surveyed this project’s permanent works. A published size with its source closes them.
- What it already pays in taxes and royalties — We have not broken down this project’s local fiscal contribution: the primary source that sets each item still has to be opened, and an act of the State is not published on press backing.
- Who promised what — We have not surveyed the public promises about this project. A dated, verifiable commitment with its source closes them.
What could stall itrisks and how to track them
- What could stall it — We have not documented this project’s risks. An identifiable vector with its source closes them.
- How to tell whether it is advancing — We have not defined this project’s indicators: what observable fact marks its progress still has to be identified.
