Are you a gold mining company owner or a C-level executive, looking for the most efficient and cost-effective way to melt your company’s gold ore? Hands down, induction furnaces are your best bet.
Induction furnaces have become the go-to solution for many gold mining companies due to their higher efficiency, melting speed, and environmentally friendly feature.
In this article we will discuss how induction furnaces can help make your gold mining operations more successful, saving you hours of melting your ore by using a run-of-the-mill furnace instead of doing it in a few minutes.
The main benefits of using an induction furnace over traditional ones are:
| Feature | Induction Furnace | Traditional Furnace |
| Fuel | Electricity | Gas or diesel |
| Emissions | None | Harmful pollutants |
| Efficiency | More efficient | Less efficient |
| Speed | Faster | Slower |
| Safety | Safer | Less safe |
When it comes to coreless inductionnaces, which are the most suitable for melting gold, it is common to mention that higher frequencies are needed for load capacities of a few kilograms
As a rule of thumb, the smaller the volume of the melts, the higher the frequency of the furnace used.
Well, previously we have already clarified what this frequency consists of, but: why do we need high frequencies to effectively melt loads of gold of kilograms or a few tens of kilograms?
The answer lies in the penetration or depth of the eddy currents that circulate through the mass to be melted, and in the behavior of alternating current at high frequencies.
For there to be induction of voltages and currents in the load deposited in the crucible, it is necessary to feed the inductor coil that surrounds the crucible with an AC voltage.
If we fed this coil with DC voltage, no matter how high that voltage was, there would be no induction in the charge of the crucible and it would remain at room temperature.
Alternating current has the property of not being distributed uniformly through the conductive material through which it flows unless the frequency is very low.
At high frequencies, it circulates only on the surface of the conductor, so the eddy currents are concentrated closer to the surface of the load, which is more efficient for heating small melts.
We are advisors and consultants to a wide range of industries—including Foundries, Steel Plants, Mining operations, Metal Mills, Universities, Military
institutions, Aerospace, and metal processing industry.
Our mission is to help clients reduce energy consumption and identify the most efficient induction furnace solutions ailored to their specific perational needs
