Chapter 1:

Application Field of Smelting Machine

Have you ever tried to obtain a pure base metal before? Be it gold, silver, iron, or the likes? If you have, then the fact that it isn’t an easy process wouldn’t need much explaining. Stick with this buying guide to get all the info you would need to pilot a sustainable gold smelting process.

Mining of Gold

To get started, it’s important to note that the Gold mining process does not leave room for miners to extract pure gold from the surface of the earth. Gold is discovered in nature as Gold ores. While this ore can be referred to as gold, they contain impurities that are quite detrimental to the market value attributed to the metal. Gold ores can be mined via three different methods.

Placer mining: Are you planning to embark on your first gold hunting quest? This method is regarded as the most explored gold mining method for amateur gold miners. It usually requires the usage of gravity and water to separate the Gold ores from other materials. The processes involved in placer mining include metal detecting, panning, cradling, sluicing, and dredging. Placer mining is the most suitable means of extracting gold dust from non-metal impurities.

By-Product Mining: unlike most other mining methods on our list, the By-product mining doesn’t place gold as its first find. This mining process involves the usage of underground tunnel and pits dogged to extract coppers, gravel, sand, and other products to extract gold.

Hard Rock Mining; most of the gold circulating the world today are results of the Hard rock mining process. For this mining process to be practical, open pits and underground mining tunnels are dogged, paving easy access for miners to access the gold ores directly from the rock.

1.1, Smelting the Gold Ores

Gold is listed amongst the most valuable precious metal available in the market. Its ability to retain an ever-growing market value have made it rank as one of the most sought out precious metal of all times. To ensure that your freshly mined gold is appreciated for the value it portrays, smelting gold ore is necessary.

How to Smelt Gold Ores

  • Chose a preferred smelting machine
  • Crush gold and place in furnace.
  • Allow to heat to over 1064 degree Celsius
  • Add cyanide solution to remove impurities while smelting
  • Pour in a mold and allow to cool.

1.2, For Recycling old gold

With gold usage dating as far back as ancient Egypt, it wouldn’t come as a surprise that over 35% of the gold materials circulating in the world today are made out of recycled gold. While gold can be recycled from electronics, dental filings and lots of other materials, we would be focussing on the process attached to recycling gold from jewelry.

Jewellery and coins are amongst the most common materials containing gold. Be it a family ornament that has withstood the test of time or gold coins passed down from generation to generation; you can acquire a handful of pure gold from them through the gold recycling process.

1.3, For Jewelry Casting

Gold and silver smelting are processes that requires as much care and precaution as possible. Smelting gold wrongly would not only affect the surface finish of the casted jewellery, it would also depreciate its market value; having the necessary smelting tools and smelting machine is a must.

It’s no news that you wouldn’t be able to cast a piece of fine jewellery with a gold material containing an impure substance. While a lot of jewellers are familiar with the traditional and homemade smelting styles that have prevailed over the years, its reliability in the 21st-century global market is continuously placed on a questionable spot when talking about how to melt down gold jewellery. The smelting reduction process involved doesn’t seem to be providing the desired output when smelting gold jewellery.

How to Use Gold Smelting Machine to Remove Impurities from Gold

  • Apply flux {oxidation compounds like Borax, Sodium Nitrate and Silica} to the gold material.
  • Place in the furnace and allow to heat at over 900-degree Celsius.
  • Pour out flux and any other impurities floating at the top of the liquified material
  • Place in a mold and allow to dry.

1.4, For Industrial Applications

Dentistry: the use of gold in the dental industry dates as far back as 700 BC. Generally known as a durable replacement for worn-out teeth and for making fillings. Gold has been able to retain its influence in the dentistry industry over the decades due to the biocompatible nature it possesses. The gold mostly used in the dentistry industry is white gold or gold alloy. To ensure that individuals are not provided with gold teeth containing impurities, the gold smelting technology has gained extensive usage around the industry.

Gold in Medicine: Gold is not just vital in the dentistry industry but even in the treatment of arthritis, cancer, and Lagophthalmos. A lot of medical equipment and diagnostic tools used in the medical sector are also by-products of the precious metal. While the need for pure gold can be compromised in the production of diagnostic tools and medical equipment—when it comes to the gold dust or gold salt required the treatment of arthritis or cancer, such compromise can cost a life. Gold smelting machines have had and still have a vital role to play in the medical industry.

FAQ Guide

Does gold lose value when melted?

No, pure gold doesn’t lose its value. Instead, it acquires more value. Since gold is mined in an impure nature, the process of melting is required to help purify the gold. All the gold materials and pieces in circulation today underwent the melting process. Although, you might want to note that the melting process involved in gold purification is a bit tedious and can lead to spillage if care is not taken. Issue of spillage creates room for loss of a substantial amount of pure gold. To avoid such problems, it’s advisable you adopt advanced melting methods when looking to smelt your recycled gold or gold ores.

How do you smelt gold with borax?

To smelt gold using borax, you would have to create a mixture of disodium tetraborate {borax} and sodium carbonate. This mixture is generally regarded as a flux. After such mixture is obtained, application of the flux on the gold before heating would enable the impure substance attached to the gold rise to the top of the cubicle when heated. Borax which is also known as sodium tetraborate or disodium tetraborate is one of the most used oxidizing agents for smelting gold. Its usage in the smelting gold process requires a mixture with sodium carbonate. Note that: when applying the borax mixture to the gold, special attention should be placed on gold materials with rough surfaces to avoid engaging in a smelting process that doesn’t guarantee the attainment of gold piece or bars of high purity.

How do you separate gold from other metals by melting?

To separate gold from other metals by melting, you would have to remove or pour out the impure substance that rises to the top of the material after a liquified form {molten} of the precious metal has been attained. It’s essential to keep in mind that for the impure substance contained in the gold material to rise to the top, the application of flux on the content must be done effectively, and the melting point for the gold materials must be observed.

How do you smelt gold jewellery?

Gold jewellery is commonly smelted by gold recyclers. Just like the process involved in smelting gold ores, jewellery requires proper application of flux on the materials before being placed in a heating furnace. To remove impurities, you must allow the jewellery melt to the required melting point. It's advisable you make use of induction heating furnace so you can accurately calculate the temperature range of the melting furnace at all times. When the required melting point is reached, the impure substance contained in the jewellery will rise to the top. Pour out the impure substance then place gold in a mold to dry.

How many degrees does it take to melt gold?

To melt gold, you would require a furnace that can heat as far as 2000 degrees Fahrenheit although the estimated melting point for gold is 1945 degrees Fahrenheit. Due to the high intensity of heat required to melt gold, utilizing an induction furnace remains the best bet for saving time and money. With smelting technique like propane torch and resistance furnace, it’s impossible to estimate the actual amount of heat reaching the precious metal at a time. Smelting gold without an accurate measure of its melting degree creates room for chaotic outcomes.

What is borax used for in melting gold?

Borax is used for oxidizing the gold piece or material before or during the smelting process. Gold smelting involved the removal of impurities from gold. Note that gold can be melted without being smelted, but it cannot be smelted without being melted. Borax, when mixed with sodium carbonate, serves as an oxidizing agent that enables impurities such as zinc, copper, iron and any other impurity in the gold rise to the top when the gold is melted to a specific degree. This process enables goldsmiths or metal melting companies to obtain gold piece or end products of higher purity.

Can you melt down gold to make jewellery?

Yes, to make jewellery, the gold material must be melted down. Jewellery has, for a long time, served as the most patronized by-product of gold. Note that due to gold's fragile nature, most times to attain a piece of shiny and more durable jewellery, pure gold is mixed with alloys. Most of the jewellery available in the global market are mixed with such materials. White gold and rose gold jewellery are by-products of this mixture. It's essential to bear in mind that jewellery casting is a complicated process. If you haven't engaged in the art before, it's advisable you consult an expert to put you through before you engage in the gold melting process.

Could we melt silver in this induction melting furnace also?

Yes, you can melt silver with our induction melting furnace. The induction melting furnace is designed to melt different types of metals. The mini and integrated melting furnace is suitable for melting a small amount of ferrous and non-ferrous {precious metal} metals. If you are looking to melt a large amount of metals like zinc, copper and other ferrous metals with our induction heating machine, you would have to opt for the motor tilting melting furnace or the hydraulic tilting melting furnace. You can check out the machine specification guide for detailed info on suitable metals.

How much gold is lost when melted?

If you are melting an 18-carat gold to obtain 24-carat gold, you will lose over 25% of the gold after the melting process. In situations where you are melting 9-carat gold and 18-carat gold combined to get 24-carat, you would lose up to 50% of the gold. The amount of gold lost is dependent on impurities and the combustible nature of the alloys contained in the gold material. In a few scenarios, you might also experience gold loss based on the melting process used and the carat of gold being melted. The gold lost during melting is as a result of the other alloys contained in the gold going out as slag or combusting into thin air.

How do you get gold from gold ore?

To get gold from gold ore, you would have to make use of an effective gold smelting technique. The three gold smelting methods available include, induction heating, propane torch and resistance furnace. Induction heating remains prevalent amongst the other two for the rare advantages it offers. While it remains one of the most expensive methods, its usage and durability can be seconded to none. In situations where you can’t obtain an induction heating machine, you can opt for propane torch. Resistance furnace is the least recommended.

How do you get impurities out of gold?

Getting impurities out of gold requires smelting and then refining. The smelting process removes impurities such as copper, iron and zinc while the refining process is necessary to extract precious metals like silver. Note that to remove impurities via smelting, a flux {oxidizing agent} is required. Gold smelting does not provide users with 99% pure gold. Obtaining 99% pure gold would require a refining process. There are a lot of gold refining companies that would enable you to remove any remaining impurities at affordable rates.
