Gold extraction

Definition

Gold extraction refers to the process of separating gold from its ore or raw materials, allowing it to be collected and refined for use in various applications. This process became increasingly sophisticated with advancements in metallurgy, particularly during the Greek and Roman periods, which significantly improved techniques for mining and processing gold.
