Ag

1. Silver ore:
Silver-bearing ores in nature often exist as native silver, argentite (Ag₂S), or argentite (AgCl), and are frequently found alongside non-ferrous metal ores such as lead, zinc, and copper. It is the initial raw material for the silver industry, where silver concentrate or crude silver is extracted through flotation, cyanidation, and other beneficiation processes, providing the foundation for subsequent silver refining.

2.Silver Concentrate:
Silver ore, or silver-bearing polymetallic ore, is a product obtained after crushing, grinding, and beneficiation (mainly flotation) processes. The silver is often found as an independent mineral such as argentite or within carrier minerals such as galena and sphalerite, resulting in a significantly higher silver grade and rich content of various valuable metals such as lead, zinc, copper, and gold. It is a key intermediate raw material in silver smelting, primarily extracted through pyrometallurgical processes (such as co-recovery in lead smelting) or hydrometallurgical processes (such as cyanidation). Its economic value is highly dependent on its comprehensive recovery capabilities.

3. Coarse silver bars/coarse silver ingots:
Silver is a metallic form initially extracted from silver ore, anode mud, or recycled materials through pyrometallurgical processes. Its purity is typically between 90% and 99%, and it contains impurities such as gold, copper, and lead. It is a key intermediate product in silver refining and requires further purification through electrolysis or chemical methods. It is often used as a raw material for refineries or as a primary trading product.

4. 24K Silver:
High-purity silver products with a purity of 99.9% (pure silver) or 99.99% (sterile silver) are usually available in the form of silver bars, ingots, or jewelry. They are pure white in color, have excellent ductility, and are chemically stable. They are one of the final forms of refined silver and are mainly used in jewelry making, silverware production, investment reserves, and high-end electronics industries.
