Today we're checking out how gold coins and bars are made - it's an amazing process using high-tech machines. Stick around as we melt down pure gold and mold it into shiny bullion.First, gold miners extract gold-bearing ore from the earth. It's then refined to remove impurities, leaving pure gold bullion. Refineries take delivery of these gold ingots or grains. Using powerful spectrometers, they verify the gold is at least 99.5% pure, meeting quality standards for investment gold.The refinery loads gold ingots into a large furnace capable of melting thousands of ounces at a time. As it heats to over 1,800 degrees Fahrenheit, the gold melts into a liquid near the consistency of honey. Workers use special tools to carefully pour the molten gold into large ladles to transfer it where needed.For coins, molds shaped like the coin's outline are prepped on a special high-speed minting machine. When the liquid gold is poured in, it rapidly spins to distribute the metal evenly across the surface through centrifugal force. This ensures a consistent thickness and finish.
