Northern Rare Earth’s Zhongxin Antai unit has broken ground on an expansion project (opens in a new tab) in Baotou’s Rare Earth High-Tech Industrial Development Zone that will add 8,000 tons per year of rare earth metals and alloys production capacity. Once completed, the facility’s annual output capacity will reach 15,000 tons, significantly scaling the company’s ability to meet demand for advanced materials in permanent magnets, alloys, and other strategic applications.

The project is being framed as a model line for efficient, energy-saving rare earth metals production. On the process side, it will feature upgraded electrolysis systems and refined workflows aimed at improving current efficiency and lowering per-unit energy consumption. On the digital front, real-time data capture systems will log key parameters such as electrolysis temperature and feed volume, enabling precision process control. Each electrolyzer will be fitted with an automated feeding machine integrated with PLC controls, eliminating the accuracy shortfalls and safety hazards of manual feeding—an innovation with economic, social, and safety benefits that could set a new benchmark for China’s rare earth sector.

To ensure timely delivery, Zhongxin Antai has established a dedicated project team, mapped detailed schedules with critical milestones, and implemented full-chain oversight of progress, quality, and cost. The company says it is applying “whole-process strict management and all-round quality improvement” principles to deliver a safe, efficient, low-energy, and compliant flagship facility.

Strategic Context

This buildout supports Baogang Group’s mandate to be the “main force” in constructing China’s “two rare earth bases”—a policy initiative designed to anchor the country’s dominance from upstream mining to high-value downstream products. By raising capacity in metals and alloys, Zhongxin Antai strengthens its position in the rare earth value chain and improves China’s ability to control pricing, supply stability, and technology direction in global markets.

Implications for the West/USA

Capacity leverage

Expanded Chinese output in refined metals and alloys could tighten Beijing’s grip on critical intermediate materials for EV motors, wind turbines, defense electronics, and hydrogen storage systems.

Process innovation

The integration of fully automated feeding and PLC-based precision control in electrolysis could reduce production costs and improve quality, challenging Western producers on both price and performance.

Policy alignment

As a state-aligned project in a national-level rare earth zone, the expansion reflects Beijing’s continued investment in industrial self-reliance and its readiness to scale high-purity, value-added REE products.

REEx Reflection

Northern Rare Earth’s latest expansion is more than a capacity boost—it’s a technology and process upgrade aimed at consolidating China’s leadership across the rare earth metals and alloys segment, with direct implications for global supply chains. This becomes essential as the West, led by America, seeks to rebuild rare earth and critical mineral supply chains.  China seeks to extend its lead.
