Hunan Zhenqiang Antimony Industry invites you to the 2026 SMM (14th) Minor Metal Industry Conference.

In 2026, global competition for critical minerals enters a white-hot phase, geopolitical maneuvering deepens, and global industry and supply chains are restructured at an accelerated pace. A new round of technological revolution centered on AI semiconductors, new energy, high-end manufacturing, and aerospace is propelling the minor metals industry into a historic period of development opportunities and profound transformation. Globally, the EU’s Critical Raw Materials Act and the US Inflation Reduction Act (IRA) continue to be implemented, the Minerals Security Partnership keeps expanding, and the trends of localization and regionalization of critical mineral supply chains intensify. Resource competition, technology barriers, and trade rule restructuring around strategic minor metals—such as antimony, indium, gallium, germanium, bismuth, selenium, tellurium, and rhenium—have become the core focus of global high-end manufacturing competition. As the world’s core supplier of minor metals, China holds a dominant global position in the smelting and supply of multiple minor metal varieties.

Against this backdrop, the 2026 SMM (14th) Minor Metals Industry Conference gathers upstream and downstream enterprises, research institutes, government agencies, financial and investment institutions, and trade service providers across the entire industry chain of antimony, indium, gallium, germanium, bismuth, selenium, tellurium, rhenium, and more. It builds a high-standard, full-chain, and in-depth exchange and cooperation platform. The conference will deeply interpret the changing global policy landscape, diagnose supply-demand patterns and price trends, analyze growth opportunities in end-use applications, and connect government-enterprise resources with cross-border cooperation opportunities. It will help enterprises accurately grasp industry trends, break through development bottlenecks, optimize supply chain layouts, and seize market opportunities, jointly promoting the high-quality and sustainable development of China’s minor metals industry.

Hunan Zhenqiang Antimony Co., Ltd. will attend the conference with great honor. We will keep pace with the times, aim at our goals, forge ahead with determination, and march forward courageously! Click to register now. We look forward to meeting you at the conference.

Hunan Zhenqiang Antimony Co., Ltd. is located in Xikuangshan, the World Capital of Antimony. It is a large private antimony smelting enterprise and the third producer, after Shining Star Antimony and Chenzhou Mining, to meet the national antimony industry access conditions for refined antimony and gold production.

Founded in 2008, the company covers an area of over 50 mu, with a registered capital of RMB 50 million. Its business scope includes: antimony smelting; antimony ore mining and beneficiation.

Since producing refined antimony and gold, the company’s annual sales revenue has grown from RMB 400 million to RMB 800 million, doubling its annual output value.

Main products: (1) Refined antimony, annual output 6,000 mt; antimony oxide, 3,000 mt. (2) 99% gold, annual output 1,000 kg. Main equipment: (1) 2 m² blast furnace, equipped with an 8 m² forehearth; (2) 8 refining reverberatory furnaces: including three 17 m² refined antimony furnaces, two 12 m² precious antimony smelting furnaces, two 8 m² low-gold ore processing furnaces, and one 4.5 m² precious-antimony converting furnace; (3) newly built 1,000 kg/year gold purification line; (4) newly built 6,000 mt/year antimony-gold ore leaching and electrolysis production line.

Main products:
Refined antimony, annual output 6,000 mt; antimony oxide, 3,000 mt
99% Gold, Annual Output 1000kg
Main Equipment:
2m² Blast Furnace with 8m² Forehearth
8 Refining Reverberatory Furnaces: including 3 units of 17m² Antimony Refining Furnace, 2 units of 12m² Precious Antimony Smelting Furnace, 2 units of 8m² Low-Gold Ore Treatment Furnace, and 1 unit of 4.5m² High-Antimony Blowing Furnace
Newly built gold purification production line with an annual capacity of 1000kg gold
Newly built leaching and electrolysis production line with an annual capacity of 6,000 mt of antimony-gold ore

Environmental Protection Status:

1. The company commenced construction in June 2008 and obtained EIA approval for trial production in October 2011, primarily processing single antimony ore to produce refined antimony. In December 2020, it obtained a second EIA approval for trial production, mainly processing antimony-gold symbiotic ore to produce refined antimony and 99% gold.

2. Flue Gas Treatment System

(1) One set of blast furnace flue gas cooling and dust removal equipment and eight sets of reverberatory furnace flue gas cooling and dust removal equipment were built.

(2) One set of SO₂ flue gas treatment system was built, featuring three-stage spray, adopting the "lime-gypsum" process, with fully automatic control, and a flue gas treatment capacity of 65,000 m³/h. One demister and one 30m high stack were also constructed.

(3) Organized waste gas emissions were achieved: after the flue gas passed through facilities including "water cooling + surface cooling + bag dust collection", and after treatment by multi-stage spray towers, SO₂ concentration was ≤200 mg/Nm³ (meeting national standards), and was then discharged through the demister and stack.

3. Wastewater Treatment and Reuse System

Including plant clean-dirty water separation and rainwater-sewage separation systems; a rainwater collection system; and a wastewater treatment system. A rainwater collection pond of 200 m³ and a wastewater treatment capacity of 2,000 m³ were built. After treatment, rainwater and wastewater were reused, with no external discharge.

For the newly built 1000kg gold per year purification line, wastewater was pumped to the desulfurization workshop, neutralized, and then sent to the absorption tower to treat SO₂ flue gas, with no external discharge.

The newly built 6,000 mt per year antimony-gold ore leaching and electrolysis line achieved closed-circuit leaching and electrolysis production, with no wastewater discharge.
