2.1, Karat Gold Manufacturing
There is a general believe that gold jewelries contain 100% gold. Contrary to this believe, there are reasons why pure gold is not used in making jewelries;
One of the major reasons is the fact that pure gold is extremely soft, it bends easily & scratches easily, making it a poor metal for jewelry. Secondly, pure gold is very bright and unlike what the popular gold in jewelry shops looks like, it does not look so attractive for jewelry making. Finally, pure golds are extremely expensive to use in jewelry casting.
In jewelry casting, “karat” is the word used to describe the amount of pure gold contained in an object. “24 karat” signifies that an object is made with 100% gold, which as we stated before is relatively soft.
Generally, jewelries are made to be stronger and durable, therefore, in the karat gold manufacturing process, other metals, silver being one of them is mixed with gold to eliminate the aforementioned reasons why 24k gold cannot be solely used for jewelry casting.
2.2, Making Gold and Silver Grains and Chips
Precious metals such as gold and silver are the most recycled metals, and they are mostly not recycled in their old shapes and sizes. Their uses vary widely and one popular use of gold and silver is the production of precious metal grains and chips.
In the process of recycling and reshaping these precious metals, they need to be melted in order to take new shapes. An induction furnace efficiently carries out this process by melting these gold and silver objects, and poured into mold with tiny shaped holes to help give the metals new tiny-grained shapes.
They can be found being used in making many crafts like; jewelries, in electronics. Most gold and silver grains are produced from scraps melted off from electronics using small gold melting furnace like the 2kg melting furnace and other induction gold melting furnace, and they can be recycled again in form of chips and grains to be used in jewelry, beautification in the world of fashion.
2.3, Gold Bar & Coin Making
Domestically, in the process of making a gold bar also known as bullions, Induction furnaces are vital in the smelting process because “refining & pouring” which is a step in the production of gold bars requires impurities be removed from gold ores in order to extract pure gold which are mostly used in producing 24karat gold bars. These bars are used in finance and investments in the financial sectors.
The round shape of gold coins doesn’t originate right from the mining fields, but they are shaped in the form through the use of induction furnaces. Gold which melts are at a temperature of 1,064°C is put into a crucible and is melted in an induction furnace, and then poured into a coin-shaped mold. This can also be done domestically using a 2kg mini melting furnace.

And in the process of producing these ornaments and objects an induction furnace is important because it acts as a heat provider where heat is the most important agent in the overall process of gold and jewelry casting. Induction furnaces heats up gold ores in the smelting process of gold mining to help separate gold from its ores. And also heats up gold above its melting point in order to dissolve them in order to be reshaped and molded into new objects.
In jewelry and craft casting, gold, silver and other precious metals are mixed to make the end products strong, durable and affordable. We previously discussed why pure gold is not solely used for jewelry and other craft making process.
However, gold plays a major role in the process and there are 3 generally known types of gold used in these processes; white gold, yellow gold & rose gold.
These varieties of gold are used based on the preference of consumers. Melting plays a vital role in achieving these processes through the use of portable gold smelting equipment, 2kg melting furnace, gold induction furnace, and gold and silver melting machine.
Smelting is the term used to define the process of applying heat to ore in order to separate them from base metals, it is the most important part of gold and silver mining process, if not done, they remain embedded in their ores, which directly affects the fineness of the metal being extracted and profit to be made from the metal.
Smelting can be carried out on different sizes of gold and silver with the use of portable gold and silver smelting equipment, mini gold melting machine like the 2kg melting furnace.
The heating phase is done in a furnace which produces heat, and a chemical reducing agent (commonly coke) is used in order to decompose the ore which in turn separates the base metal from its ore.
3.1, How to Smelt Gold and Silver by Propane Kiln
Propane kilns work on the very rule as other forced air furnaces with the exception of that propane is used instead of oil or petroleum gas to consume or power that uses resistance to produce heat. Propane is efficient in firing furnaces and do not need electricity to fire up the kilns.

In terms of sizes; the induction furnaces can be made to be compact and small in size, can be used in small and medium scale metal working industries.
What is the Difference between Smelting and Melting?
Melting is a physical process that results in the change of state of the matter of a substance from a solid to a fluid or liquid. This happens when the internal energy of the solid increases, commonly caused by the use of heat or pressure, which builds the substance’s temperature to the melting point. At the melting point, the ordering of particles or atoms in the solid separates to a less arranged state, and the solid ‘liquefies’ to turn into a fluid. A gold and silver melting machine is an appropriate melting equipment used in melting. Smelting on the other hand is the process of applying heat to ore to extricate a base metal. It is a type of extractive metallurgy. It is used to remove numerous metals from their ores, including silver, iron, copper, and other base metals. Gold smelting machines plays a vital role in this process. The principle difference between melting and smelting is that melting transforms a solid substance into a fluid while smelting changes an ore over to its purest structure.
Can you Melt Gold and Silver off Electronics?
Precious metals like gold and silver are used in electronics like phones, cameras, laptops, televisions and other devices. They are mostly used in the internal connection of components. It is known that a phone contains about 0.2g of gold. Eventually, when these devices damage and are no longer in use, these precious metals need to be extracted in order to be recycled. The extraction is relatively simple and “melting” plays a significant role in the process. Good news is that it can be done domestically with the use of mini gold melting furnaces like a 2kg melting furnace.
What is the Best way to Melt Gold and Silver?

How do you Smelt Gold with Borax?
Using borax in smelting which is a process in gold mining is a technique which uses borax as a flux to help purify the gold concentrate. Borax assists with reducing the smelting point temperature of the ore. This implies that smelting will happen rapidly and permit the precious metal to settle out. With some borax, heat, and a little skill, it’s feasible to remove pure gold from a sample of ore. This process can be easily done at home. A gold miner can granulate and wash a piece of ore, at that point blend it in with borax in a plastic sack. The sack is then positioned in a bowl or crucible and heated. The heating activity is the thing that triggers the borax to go to work. When the borax liquefies, it brings down the melting temperatures of everything in the ore. As the entirety of the ore melts down, they separate from each other. As the process proceeds, the borax makes the different minerals contained in the ore oxidize and breakdown significantly further. Gold is unaffected by this reaction and sinks to the lowest part of the mixture, and settles.
How do you Separate Gold from other metals by Melting?
Gold parting is the isolating of gold from other metals. Gold is mixed with other metals and is mostly used in jewelry making. Separation of gold from other metals is no rocket science because it can be carried out by individuals at homes. However, excluding the following steps involved in the process, one major tool needed is to do this is a gold melting furnace such as an induction melting furnace, because to cheaply carry out this process you need access to a temperature furnace.

Extreme heat is needed to melt gold, and electric induction furnaces provides the needed heat. And with the ability for the temperature to be regulated and controlled makes gold jewelry melting easier for individuals. You can simply pour in your gold jewelry into a crucible. Place it into an induction furnace and heat it up to a temperature little above 1,064°C. Then, pour out your melted gold into a mold.
How do you Get Gold from Gold Ore?
Gold is typically found alone or alloyed with mercury or silver, yet can likewise be found in ores like; calaverite, sylvanite, nagyagite, petzite and krennerite. There are several ways known to get gold from gold ore. But the commonly known technique is the use of Cupellation Method. Cupellation includes treating ores under high temperatures in order to separate precious metals, like gold and silver, from base metals. Base metals, like copper, zinc and lead, will oxidize though precious metals don’t. Cupellation includes liquefying metallic ores in induction furnaces at temperatures more than 960 degrees Celsius; at this temperature the base metals oxidize while gold stay on top of the mixture.
How do you get Impurities Out of Gold?
One of the methods used in purification of gold is the use of gold smelting machines; Heating crude gold with gold melting furnaces makes the ore dissolve while the impurities are made to float to the surface using borax, where they can be taken out. There is yet another method used to purify gold which includes the Cupellation process. Cupellation includes treating ores under high temperatures in order to separate precious metals, like gold and silver, from base metals. Base metals, like copper, zinc and lead, will oxidize though precious metals don’t. Cupellation includes liquefying metallic ores in induction furnaces at temperatures more than 960 degrees Celsius; at this temperature the base metals oxidize while gold stay on top of the mixture.
What flux do you use to Smelt Gold and Silver?
An important chemical used to hasten and improve the quality of the end product of the smelting process is a Flux. A smelting flux is basically a chemical added at intervals in the smelting mixtures to remove the impurities sticking firmly to the extracted pure metals. There are various flux available to use in gold and silver melting, but the highly recommended and effective one in major use is the Borax.
How much Borax is required to melt Gold?
The amount borax of borax needed to melt gold directly depends on the amount of gold to be melted in a gold melting machine. With increase in amount of gold to be melted also increases the amount of borax to be used ̶ at least, half the quantity of gold to be melted.
How do you melt Gold Dust?
Gold melting is the first and major step taken to recycle gold. And there are different methods used in melting gold dust and they include; gas torch, gas furnace, electric furnace, induction furnace, coal furnace. Gold melting machines like the Induction furnace is the option to melt gold dust because it is safer, environment-friendly, and well-controllable.
What are the Advantages of Electric heating Over other Types of Heating?
Heating is essential and required for different purposes domestically, industrially for metal melting, hardening, tempering, welding. Although there are different methods of heating, not all are environment-friendly. With a lot of changes occurring in our environment like the ozone layer depletion, flooding and altered weather seasons, industries have been obliged to find and eliminate potential causes of these conditions. Therefore, electric heating is increasingly becoming a viable means of heating amongst others, and it is as a result of the advantage it has over the rest. Advantages of electric heating over alternatives include;
- Precise heating Operations
