What is Gold?

Gold is a chemical element with the symbol Au and atomic number 79, valued for its unique properties. It is cherished for its beautiful luster and malleability, making it ideal for jewelry and decorative arts. Additionally, gold's excellent conductivity and resistance to tarnish make it indispensable in electronic and precision engineering applications.

Recovery of Gold from Diverse Sources

Auris Noble specializes in the recovery of gold from diverse sources including outdated electronic devices, industrial waste, and jewelry scraps. These items are collected systematically to extract gold content using eco-friendly and efficient methodologies. Examples include gold from the circuit boards of mobile phones, the plating from connectors, and broken pieces of jewelry which are processed to extract valuable gold.

Refining Process of Gold

Once recovered, the gold undergoes a comprehensive refining process to remove impurities and other metals. This includes melting the gold in a furnace, treating it with chloride which removes silver, followed by electrorefining to improve purity. The result is 99.99% pure gold, which is then molded into bars, coins, or granules depending on the intended use.

Applications of Refined Gold

The high-purity gold produced by Auris Noble is used across several industries. In technology, it is employed in the manufacturing of corrosion-resistant electrical connectors in computers and mobile phones. In the jewelry industry, it serves as a primary material for fine jewelry; in the financial sector, it is used to create investment-grade gold bars and coins prized by investors worldwide.
