Induction furnaces are among the best furnaces used for the smelting of metals and the melting of scrap materials. These furnaces are an advanced version of the electrical powered furnaces and use induction heating to produce heat, which is a much cleaner way of heating and melting metals. Therefore, if you are looking to produce the purest form of precious metals, using an induction furnace for the smelting process is the best option.
What Precious Metals Can Be Smelted in Induction Furnaces?
Many types of precious metals can be smelted in induction furnaces. Among the most common precious metals are gold and silver which are 
smelted to make gold or silver coins and bullions. Other precious metals which can be smelted in induction furnaces include ruthenium, platinum, iridium, rhodium, and osmium. Most of these precious metals are smelted to make fashion jewelry and others are smelted for different industrial uses.
Why Use Induction Furnaces for the Smelting of Precious Metals?
Induction furnaces are used to produce the purest form of metals. These furnaces also provide numerous benefits over traditional furnaces, such as gas, oil, combustion, electrical, cupola, and arc furnaces. Firstly, induction furnaces use induction heating to produce heat which is a non-contact form of heating. Therefore, the furnace does not emit smoke, dust or any harmful pollutants as it does not require a fuel to be burnt to produce heat.
Furthermore, induction furnaces feature high-frequency magnetic fields which are capable of producing high amounts of heat to stir hot metals and ensure the alloys mix completely while melting. Additionally, heat is produced directly and instantly in induction furnaces, so all mining companies can take advantage of this and maximize their rates of production.
Last, but not the least, induction furnaces optimize a well-controllable localized heating system which produce heat without emitting gas, smoke or other harmful pollutants. The rate of heat loss is also relatively lower than other traditional furnaces and these furnaces are a lot safer and easier to control and promote a better working environment.
So, if you are looking to obtain the purest form of a precious metal, using induction furnaces for the smelting process is the best option.
