Presentation Title NatureAlu: Manufacturing High Purity Aluminum from the Concept Idea to the Production Plant
Author(s) Jean Francois Desmeules, Denis Mazerolle
On-Site Speaker (Planned) Denis Mazerolle
Abstract Scope NatureAlu produces high purity aluminium (4N or 99.99% and more) using a process known as Fractional Crystallisation. The idea of starting such a company initiated a few years ago when two retired metallurgical engineers saw an opportunity for a North-American based 4N aluminium producer. A team was built and the design of a purification equipment began. Resources from research centers were used to help improve the process parameters. A pilot plant was built to test the equipment in real production size. Using results from experiments made with the pilot plant helped streamline the whole production process and optimize the full-size plant layout and budget. The plant is starting production in Q3 2020. The purpose of this paper is to present the many interdependent steps and actions required to achieve the goal of opening a production plant starting with a project idea, including market assessment, technology development, financing and project management.
