Precious Metals Smelting

What is precious metal smelting?

Precious metal smelting is the process of converting metals such as gold, silver, or platinum into a liquid state at high temperatures. This allows them to be purified, removing impurities, and molded into specific shapes (e.g., ingots) for later use or analysis.

Smelting is a crucial step both in the extraction of virgin metals from ores and, very significantly, in the recycling cycle, allowing these valuable resources to be recovered and given new life from scrap metal, unused jewelry, industrial waste, and other materials.

Applications in jewelry, electronics, dentistry and investment

  • Jewelry: Casting is essential for creating jewelry pieces, allowing gold, silver, or platinum (often alloyed) to be melted and poured into molds to create specific designs, from rings to pendants. It's also used in jewelry repair and recycling.
  • Electronics: In the electronics industry, smelting is crucial for component recycling, allowing the recovery of precious metals (gold, silver, palladium) from circuit boards and other waste. It is also used to make special contacts or solders.
  • Dentistry: Foundry is used to manufacture dental prostheses such as crowns, bridges, and inlays using alloys of gold or other precious metals, which are melted and molded with high precision. It also allows for the recycling of metal from old teeth.
  • Investment: For investment purposes, smelting is a key step in the production of gold, silver, or platinum ingots and coins. It ensures purity and allows the metal to be given a standardized and recognizable form, essential for its trading and storage as an asset.

Metals we melt in Repialjo

Golden undoing

Gold is highly valued for its beauty, malleability, and corrosion resistance. Through recycling and smelting, we recover gold from diverse sources such as disused jewelry, coins, dental waste, and electronic components. The smelting process purifies the gold, removing impurities and allowing it to be transformed into high-purity ingots or granules, ready for reuse in the jewelry industry, investment, or new technological applications.

Silver Foundry

Silver, known for its luster and conductivity, is found in a wide range of objects, from jewelry and flatware to industrial contacts and photographic waste. Our recycling and smelting process allows us to efficiently recover silver from these materials. Smelting is crucial for separating silver from other metals and obtaining a refined product, which can be cast into ingots or granules for re-entry into the market.

Platinum Foundry

Platinum is a dense, ductile, and extremely corrosion- and heat-resistant metal, prized in high-end jewelry, automotive catalytic converters, and laboratory equipment. Platinum recycling is complex but vital due to its scarcity. Smelting plays an essential role in purifying and consolidating recovered platinum, transforming it into manageable forms for reintroduction into industrial or investment applications.

Palladium Smelting

Palladium, a member of the platinum group, is key in the automotive (catalysts), electronics, and dental industries. Its growing demand makes recycling essential. Through specialized recycling processes, including smelting, we extract and purify palladium from its secondary sources. Smelting produces refined palladium, ready for reuse and contributes to a more sustainable supply chain.

Casting technologies we employ

Induction casting

At Repialjo, we use induction melting, an advanced technology that allows us to fuse precious metals with unmatched precision and efficiency. This process, which relies on the generation of heat through electromagnetic fields, offers significant advantages.

High Precision - Speed and Efficiency - Homogeneity - Less Pollution

High-precision furnaces

We use high-precision furnaces specifically designed for precious metal smelting. These furnaces guarantee absolute control over the process, allowing for:

  • Precise Temperature Control.
  • Controlled Atmosphere.
  • Superior Homogenization.

Our high-precision furnaces are essential to achieving the purity and quality our customers demand in the smelting and recycling of precious metals.

Temperature Control and Inert Atmospheres: Keys to Purity in Foundry

At Repialjo, precision is essential. Therefore, rigorous temperature control and the use of inert atmospheres are cornerstones of our precious metal casting process.

Temperature Control: Ensures optimal melting, avoiding overheating that can degrade the metal and preserving its valuable properties.

Inert Atmospheres: The use of gases such as argon or nitrogen protects precious metals from oxidation and contamination, ensuring exceptional purity in every casting.

This combination of precise control and atmospheric protection allows us to offer the highest quality precious metals, meeting the most demanding industry standards.
