Gold smelting process is the most important in the final stages of processing the gold. In the gold mining industry the smelting process used to make a Dor Bar and purification process that utilizes heat with a temperature high pressure. In general, the most basic definition of a gold smelting is the final stage of the process of refining gold from gold processing.
Before stage gold smelting process, The mining industry carry out a gold mineral mining activities from the earth, where the mining process through several stages of processing. The process of extracting and gold mineral search is an initial stage of mining. Then proceed to the processing of minerals from the mining area to the into mineral processing systems. Some ways of processing the gold minerals in the mining industry before the final stage gold smelting process, such as the processing of gold by Heap leaching methods, flotation process which produces mineral ore concentrate, tank leaching process is the processing of gold by washing or the process of dissulotion gold from mineral rock in the tank which would later produce a mineral concentrate gold ore.
After processing the gold mineral and forming the concentrate, the final stages to make dore bars and make 99.99% pure gold is through gold smelting process. In the process of smelting gold concentrate material will be put into a furnace, and the heat reaches a temperature of approximately 1,064 degrees Celsius, and some additional chemicals in the smelting process.
In the early stages of the process of smelting gold from the concentrate, through the fusion stage which is the stage of placing mineral ore concentrate that has drained from the extract into the container or a bowl made of carbon materials. At this stage, mineral concentrate given the additional some chemicals such as borax, soda ash, or ammonium chloride (NH4Cl) or some other chemical.
After the mixture of chemicals ores and mineral concentrates has completed the mixing stage, then pour stage of concentrate into gold smelting furnace with a very high temperature heat, to stabilize and maintain the mineral ore into the metal melt. In the process of smelting metal mineral ore in the smelting furnace of fire burns with a temperature of around 1062 ° C, which causes oxidation of minerals and forming a solid into a liquid system. At the core temperature condition gold metal will be raised above the melting point and cause the results of gold concentration. Gold smelting process will remove impurities from high-value metals.
Usually, the melting process is done again, to produce gold metal with a higher level of 99.99%. The smelting process created a gold ingot into the mold. Then from this gold ingot to be used for a variety of purposes in industry, such as in the electronics industry, the purposes for gold jewelry, for the necessity of gold coins or a variety of other equipment in the industry.
This is video a gold smelting process in the gold mining industry.
