Phoenix Tailings acquires Machinery Partner to bring AI-driven automation to rare earth refining

Phoenix Tailings, a Woburn, Massachusetts-based rare earth mining and refining company, has acquired Boston-based industrial software firm Machinery Partner. The deal, announced May 8, 2026, adds an AI-driven operational software platform already deployed at hundreds of U.S. industrial sites. Machinery Partner co-founders Clement Cazalot and David Blair join Phoenix Tailings as chief operating officer and vice president of data and automation, respectively. Financial terms were not disclosed.

This acquisition is a deliberate move by Phoenix Tailings to differentiate its domestic rare earth processing platform through digital infrastructure rather than simply replicating traditional Chinese refining methods. The company operates a vertically integrated process spanning extraction, separation, refining, and metallization, with a stated zero-waste, zero-emissions philosophy. By integrating Machinery Partner's predictive monitoring, AI-assisted chemistry optimization, and automated process controls, Phoenix Tailings aims to improve production yields, increase equipment uptime, and reduce manufacturing costs. This fits the pattern of a company using software and automation to compress the qualification and scale-up timeline for a technically difficult industrial process — rare earth refining — that has historically been dominated by Chinese supply chains. The move also reflects the broader convergence of industrial manufacturing and AI-driven operational technology in sectors tied to strategic national supply chains.

For Phoenix Tailings, the real test will be execution: integrating a software platform built for general industrial sites into the specific, high-temperature, chemically complex environment of rare earth refining. The company must now demonstrate that AI-driven process controls can meaningfully improve separation chemistry yields and environmental compliance at production scale. If successful, this acquisition could give Phoenix Tailings a defensible technology moat in a market where most competitors are still focused on hardware and chemistry alone.
