They use high temperatures from a large furnace, pressure, and chemicals to remove impurities. In this process, workers purify gold, silver, platinum, or the targeted precious metal. Nobody wants to mess with the environment right? Refining And PouringĪfter the extraction, it’s time for refining the metals. Another reason for avoiding this method is that this method deals much greater damage to the environment. This method is avoided by many miners as it is expensive and the yield is comparatively very low. Ore Processing – In the Ore Processing method, miners use cyanide to crush the rocks containing small amounts of gold or silver. Though the miners get a decent amount of precious metals like silver and gold, the main purpose of the By-Product method is to mine gravel, copper, or sand. The main difference is that in this method precious metals are not the target. In this method, miners use underground tunnels or open wells to retrieve silver, gold, and other precious metals like platinum and palladium from rocks.īy-Product- The By-Product method is very similar to the Hard Rock method. Hard Rock- Hard Rock is the most used method for the extraction of precious metals. In this method, people use metal detection, panning, dredging, sluicing, and cradling and utilizes gravity and water to isolate the precious metal from other materials. Placer- This method is mostly used by amateur miners. The most common ways to mine precious metals like gold and silver are Placer, Hard Rock, By-Product, and Processing Ore. But time has changed and people are using different methods which are more convenient and effective. Before, hydraulic mining machines were used to find and separate precious metals like gold, silver, or platinum. Whether it’s gold or silver, it has to be located and extracted properly. The first step is the extraction of the mineral. Here are the steps that are followed to create bullion. But from extracting the mineral to striking the brand mark, the making process of bullion is way more elongated and complicated than that. Just pour liquid gold or silver in a frame and it’s done. When you look at bullion, you might think that it is fairly simple to create one. So, you can say bullion plays a pretty important role in the economy. They help the government to control the market and currency inflation. So, the companies try to make them as pure as possible.īullions are often used by governments and central banks as a reserve asset. The purer the bullion is, the higher its value. The purity of bullions has to be at least from 99.5% to 99.9%. The main condition of bullion is that it has to be of high purity. What is bullion? Bullion is silver and gold with very high purity that has been kept in the form of coins, bars, or ingots.
