6.1.3 Arc furnace

An electrical furnace is also a good equipment for melting gold and other precious metals. There are two different types of arc furnaces: Direct arc furnace, and indirect arc furnace.

In direct arc furnace, its chamber is lined with materials that are refractive in nature. The arc is positioned between the electrode and charge. There are three electrodes that are made of graphite or carbon. These electrodes are projected from the top of the furnace. A three-phase supply is provided, and the current goes through them via the charge (material to be melted). This reveals that the arc is in direct contact with the charge; this makes it possible for this kind of furnace to produce the highest temperature for melting.

On the other hand, an indirect arc furnace is formed between the two electrodes and the heat that is produced gets to the charge through radiation. Because there is no direct contact with the charge, the heat produced by indirect electrical charge is lower when compared with the heat generated by direct electrical arc furnace.

6.1, Equipment for melting precious metals

The three types of furnaces outlined above are useful for different purposes. If you are targeting a very small-scale precious metal melting (mostly at home or in a small foundry), it is advisable that you should use the propane burner. It is the cheapest and less dangerous.

However, for a medium-sized foundry or metalworking workshop, the electric arc furnace may be used. Its production capacity is larger than that of the propane burner, but it is less than that of the induction melting furnace.

The induction melting furnace for the precious metals are the latest technology in town. Its capability is huge, and the amount of materials it can handle increases based on the design of the furnace. It is also the safest and more efficient method for melting precious metals.

6.3, Equipment for melting precious metals

Unlike other kinds of metals, the precious metals are more delicate and destructible. So, it is important that they are handled with utmost care. To obtain a good result while melting precious metals, the following safety measures are necessary:

• Corrosive nature: Precious metals such as gold, silver, platinum, and others can corrode if they are not handled carefully. It means they can lose their shining surface when scratched. So, make sure your precious metals are not stored or placed near other metals or hard materials that can scratch them.
• Oxidation: When exposed to excess oxygen during melting, most precious metals can be oxidized. When oxidation takes place, a precious metal may lose its physical or even chemical properties. To obtain precious metals in their natural and good states, it is advisable that an anti-oxidation environment should be used. All induction melting furnaces have anti-oxidation systems. Otherwise, the precious metals can be covered with inert gases to prevent oxidation during the melting processes.
• Impurities: Sometimes, some alloys of certain precious metals may contaminate the final precious metal if the melting procedure is not done well. In this case, it is important to note the different melting points of the constituent elements in order to guarantee that they are perfectly melted and the precious metals are purified.

7. Cost: If you are starting out as a metalmaking company owner, you may want to consider the cost or price of getting a melting furnace before settling down on one.
8. Compatibility: Sometimes you may need to combine one or two technologies together to achieve better metal melting performance. In that case, choose a melting furnace that can work well with other technologies.
9. Environmentally friendly: Nowadays, every country makes laws that will make sure your melting operations will not affect the environment or the people living in it. So, buy a furnace that is less polluting and has no harmful effects on people working in your company. More information about environmental friendliness is provided below.
10. Warranty: Do not buy a melting furnace that has no warranty on it. This means that the manufacturer is not quite sure of the quality of their products. You should ask for, at least, one or two years warranty on whatever furnace you are buying.

7.2, Environmental and legal considerations while using a metal melting furnace

The reason why some countries make it necessary for operators of metalmaking companies to obtain licenses before operating is to make sure that their operations are legal and environmentally friendly.

Here are some important legal and environmental considerations you should take before or in the course of operating a metal melting company:

1. Location: Make sure you choose a place that is not in the middle of a residential area to avoid being disrupted by the other residents may claim that your plant or factory is making too much noise.
2. Government papers and licenses: Obtain all the required documents before starting your metalmaking factory or company. Some delegations from local health or business affairs ministries may visit your factory to be sure it is designed or built to the standards.
3. Less pollution: Only use equipment or machines that will produce minimal or no noise, water, air, and land pollution. It is mostly unacceptable in many nations to run a metal melting operation that is dangerous to human health and safety. So, make sure you are using a technology that can guarantee some safety for people.
4. Renewable technology: One of the best ways to reduce or eradicate pollution is to use the latest technology in metal melting. Take for instance, the induction melting furnaces are known for their clean and pollution-free operations. It is very important that you use a melting furnace that has renewable wastes.
