The Journey from Raw Metal to Shiny Gold & Silver Bullion: How Minting is Different from Casting

From Unprocessed Ore to Fine Metal.

There are various phases involved in the transformation of bare metal into brilliant gold and silver bullion. Begins with mining and extraction from the ground. To lessen its size and get it ready for processing, there will be crushing and grinding. The next step in the process is the chemical separation of the gold and silver from extraneous contaminants. At this point, purified gold and silver can be cast into bullion bars or coined into coins. Bullions are normally packaged in protective materials after they have been created and approved.

Minting vs Casting: Two Methods for Making Bullion


Casting has existed for at least six thousand years, and although ancient and modern techniques are very different from one another, the fundamentals remain the same. 

The casting method is the most economical. To ensure that every cast bar is produced with a consistent weight, size, and shape, a mold needs to be first made. Extreme temperatures are used to liquefy a pure, refined form of gold or silver itself. That is 1,948°F (1,064°C) for gold.  

Because the company can do this operation quickly and inexpensively, these bars are frequently offered at near-spot pricing.

Cast bars have a more natural appearance. But there may be some sharp edges on these bars.


Traditionally, cast bars were the precursors to minted bars.

They were then punched with a die after being put through a machine that compacts them into a long, thin sheet. Each piece, which is frequently spherical or rectangular, is polished after being rinsed with acid. Each piece is imprinted with a unique number using a big press, ensuring that they are of the same length.

The created bullion is examined once again, polished, and wrapped after the designs are finished. Each piece of bullion that is struck, whether it be a gold coin or a silver bar, also has a stunning shine.

The price will be higher compared to cast bullion because minted bars have a premium.
