Our team is one of the most experienced in the industry. We cover the complete range of a phosphate project including geology, mining, beneficiation, sulfuric acid, phosphoric acid, fertilizers, and related products including fluorides, uranium, and rare earths.
Project-based business model.
- A project is identified; a team is assembled; it works together for precisely as long as is needed to complete the task; then the team disbands (“Hollywood Model”)
- This short-term, project-based business structure is an alternative to the corporate model and offers flexibility and lower cost to the client
- Ad hoc teams can carry out projects that are large and complex, requiring many different people with complementary skills
- A core staff provides Project Management and key Phosphates Expertize
- Project Execution can carried out, when needed, by an international contractor
