Supply Chain

Silver Supply Chain: From Mine to Market

Silver supply comes from primary silver mines (~28%), byproduct of copper/lead/zinc/gold mining (~55%), and recycling (~17%). Mexico is the largest miner (~23%), followed by China, Peru, Chile, and Poland. Unlike gold, silver supply has been essentially flat for a decade as declining ore grades and limited new mine development offset production from existing operations. The demand side is being transformed by solar photovoltaics: silver paste for solar cell metallization now consumes 6,000+ tonnes/year and growing rapidly, making it the largest and fastest-growing industrial application. Each solar panel requires approximately 10-20mg of silver. Industrial demand (solar, electronics, brazing, ethylene oxide catalysts) now exceeds 55% of total demand, with investment and jewelry making up the remainder.

Production Geography

Global Silver production is led by Mexico, which accounts for approximately 23% of world output, followed by China. The full list of major producing nations includes Mexico, China, Peru, Chile, Poland. This geographic concentration means that disruptions in key producing regions can have outsized impacts on global supply and pricing.

Extraction Methods

Silver is extracted using the following primary methods:

• Byproduct of copper, lead, zinc, and gold mining
• Primary silver mining

Processing and Intermediate Products

Silver is primarily sourced from Argentite (Ag2S), Native silver, Silver-bearing galena and chalcopyrite. After extraction, the raw material undergoes multiple processing steps including beneficiation, chemical treatment, and refining to reach the purity levels required by downstream industries. Typical ore grades range from 100-500 g/t (primary); byproduct varies.

Supply Chain Vulnerabilities

Key vulnerabilities in the Silver supply chain include concentration of 23% of production in Mexico, limited processing capacity diversification, and long lead times for new mining projects. Monitoring these vulnerabilities remains important for supply chain resilience planning.
