I. Why Sichuan Merits Separate Analysis

In China's non-ferrous metals landscape, Sichuan's significance lies not in aggregate output but in the concentration of strategically critical minerals. Fifty-seven percent of China's confirmed hard-rock lithium resources lie within the Ganzi and Aba prefectures. The Maoniuping deposit in Mianning County, Liangshan Yi Autonomous Prefecture, has been confirmed as the world's second-largest producing light rare earth mine, with a resource volume of 9.6656 million tonnes of rare earth oxides. Panzhihua hosts the world's single largest known vanadium-titanium magnetite resource zone. These three mineral types — lithium, rare earths, and vanadium-titanium — are respectively the core inputs for EV batteries, advanced functional materials, and aerospace structural alloys, positioning Sichuan's non-ferrous industry at a strategic weight far exceeding its output ranking.

II. Geographic Distribution of Industrial Clusters

Sichuan's non-ferrous metal industry shows a pronounced geographic banding pattern closely aligned with the province's ore deposit geology.

The Panxi Region (Panzhihua City and Liangshan Yi Autonomous Prefecture) anchors the vanadium-titanium and rare earth clusters. Panzhihua's industrial corridor runs along the Anning River valley, hosting an integrated mining-smelting-processing chain for vanadium-titanium products. The Mianning-Dechang corridor in Liangshan is the primary light rare earth metallogenic belt, where the Maoniuping and Dachang deposits together constitute two super-large ore fields.

The Western Sichuan Plateau (Ganzi and Aba prefectures) is defined by spodumene-type lithium deposits. The Jiajika deposit in Kangding, Ganzi, holds confirmed resources of 1.8877 million tonnes of lithium oxide — Asia's largest spodumene deposit. The Dangba deposit in Ma'erkang, Aba, has similarly confirmed resources exceeding one million tonnes. The high ore grades and consistent deposit thickness make these fields a benchmark for domestic spodumene quality.

The Chengdu Plain and basin fringe concentrates downstream processing. Leshan City, leveraging abundant hydropower and mature industrial infrastructure, has become the base for Tongwei Yongxiang's high-purity polysilicon operations, deeply integrated with the photovoltaic supply chain. Yibin and Chengdu host cathode materials, electrolytic copper foil, and mid-stream lithium battery component manufacturers.

III. Leading Enterprise Structure

Pangang Group (Panzhihua Iron and Steel Group) is the dominant player in the Panxi vanadium-titanium sector. Its product portfolio spans vanadium pentoxide, ferrovanadium, vanadium nitride alloy, and vanadium electrolyte for flow batteries. In 2023, Panzhihua's vanadium-titanium industry generated total output value of RMB 52.1 billion — for the first time surpassing the city's steel sector. This structural inversion marks a milestone in the city's transition away from steel dependency.

Tongwei Group (Tongwei Co., Ltd.) operates the world's first single-site polysilicon production base exceeding 100,000 tonnes of annual capacity in Leshan. Polysilicon falls within the high-purity silicon smelting segment of the non-ferrous metals classification. The dramatic decline in polysilicon prices through 2023-2024 pushed Tongwei's revenue down to approximately RMB 92 billion in 2024, with a full-year net loss — signaling a sector-wide consolidation cycle underway.

Zhongxi (Liangshan) Rare Earth Co., Ltd. is the principal deep-processing vehicle for Mianning rare earths, operating under the China Rare Earth Group's central-local cooperation framework. In 2023, Sichuan's five economic departments jointly issued a rare earth industry development roadmap targeting total sector output exceeding RMB 100 billion by 2027, with Liangshan carrying the majority of planned capacity expansion.

On the lithium mining side, Rongda Lithium (Ganzi), Chuanneng Power's Lijia Gully project (Aba), and Jinxin Mining are the principal operators. All three have active capacity expansion programs in 2024, collectively adding substantial annual ore-processing throughput.

IV. Upstream-Downstream Supply Chain Structure

The supply chain depth of Sichuan's non-ferrous industry varies significantly by metal category.

The vanadium-titanium chain is largely vertically integrated within Panzhihua: from vanadium-titanium magnetite mining and beneficiation through titanium sponge smelting to titanium plate rolling and titanium alloy fabrication, extending downstream to titanium dioxide and high-performance titanium components. The vanadium branch has expanded into vanadium electrolyte and vanadium redox flow batteries, which Panzhihua has designated as a priority new-energy investment direction.

The lithium chain achieves reasonable completeness but remains concentrated in mid-upstream stages. Sichuan covers the arc from mining and spodumene concentration through lithium salt extraction (lithium carbonate and lithium hydroxide) to cathode materials (LFP and NCM) and battery cell assembly. In 2023, Sichuan ranked first nationally in basic lithium salt output and cathode material production, second in anode materials, and accounted for approximately one-sixth of national power battery output. Battery management systems and vehicle-level integration remain areas of relative weakness.

The rare earth chain has a visible gap in deep-processing conversion. While Mianning generates substantial rare earth concentrate and oxide output, the local conversion rate into high-value products — sintered NdFeB magnets, rare earth luminescent materials, and catalytic applications — remains low. A portion of concentrates continues to flow to processing hubs in Jiangsu and Shandong, with value capture occurring outside Sichuan. This "resource-rich, processing-lean" structural imbalance is the defining constraint of Sichuan's rare earth sector.

V. Transformation Challenges and Structural Tensions

Sichuan's non-ferrous industrial transition faces several structural headwinds. The tension between power-intensive smelting operations and hydropower variability remains unresolved: while wet-season electricity costs on the western plateau are extremely competitive, dry-season power rationing has intermittently constrained polysilicon and aluminum output since 2022.

Upstream mine development in ecologically sensitive Ganzi and Aba also navigates stricter environmental permitting requirements. Several capacity expansion projects in 2024 experienced permitting delays that pushed actual commissioning timelines beyond initial schedules.

New-energy metal price cycles have exposed concentration risk sharply. Lithium carbonate prices fell from over RMB 500,000 per tonne in 2022 to below RMB 100,000 by 2024; polysilicon prices declined more than 70% over the same period. Sichuan enterprises concentrated in single product lines faced significant asset impairment pressures during this downturn.

From a national policy perspective, the Panxi rare earth and vanadium-titanium resource zones remain subject to annual extraction quota controls. This total quantity management system, while preserving strategic reserves, also imposes institutional constraints on market-driven capacity expansion.

VI. Relevance for Upstream Suppliers

The rapid structural evolution of Sichuan's non-ferrous metals cluster has driven parallel expansion in demand for industrial equipment, process chemicals, environmental engineering, and specialized services. National-substitution equipment for vanadium-titanium smelters, flotation reagents and filtration media for lithium beneficiation plants, solvent extraction consumables for rare earth separation circuits, and tailings management and mine safety engineering are among the most closely matched upstream supply categories for this provincial industry base.

Sales teams supplying these upstream products and services to manufacturers in this sector can use Tianxia Gongchang to filter factory directories and decision-maker contacts by province and industry segment.
