Recycling precious metals and turning them into ingots is a complex
and specialized process that includes various steps. This process
begins with the collection and separation of waste containing
precious metals and finally ends with the production of pure metal
ingots. In the following, we explain each step of this process in detail:

Recycling precious metals and turning them into ingots is a complex and specialized process that includes various steps. This process begins with the collection and separation of waste containing precious metals and finally ends with the production of pure metal ingots. In the following, we explain each step of this process in detail:

۱.COLLECTION AND SEPARATION OF RAW MATERIALS

Collection: The raw materials include electronic waste (such as old mobile phones, computers, and electronic components), industrial scrap, old jewelry, automotive catalysts, and even batteries. These materials are collected and transported to recycling facilities.

Separation: The raw materials are separated manually or using specific machinery. The goal is to isolate the materials containing precious metals from other materials such as plastics, glass, and base metals.

۲.CRUSHING AND MILLING

After separation, the materials containing precious metals are crushed into smaller pieces. This is done using crushing machines. These pieces are then milled into finer particles in specialized mills. Crushing and milling the materials help separate the metals from other substances, improving the efficiency of subsequent chemical and thermal processes.

۳.MELTING AND METAL RECOVERY

Melting: At this stage, the crushed materials are melted in special furnaces. The furnace temperatures are usually very high to ensure the precious metals separate from other substances. Recovery: Due to their higher weight and density, the precious metals settle at the bottom of the furnace, separating from other materials. Non-metallic substances and impurities rise to the surface as slag and are separated from the metals. In some cases, chemical processes are also used to separate the precious metals from othermaterials. For example, dissolving metals in acids and then precipitating them can aid in the separation and recovery of metals.

۴.REFINING AND PURIFICATION

The recovered metals may still contain impurities. To achieve the desired purity, the melted metals may need to be refined several times. Chemical Refining: In this stage, methods such as electrolysis or dissolution in specific acids are used. Electrolysis is particularly effective for purifying metals like gold and silver. Thermal Refining: Some metals are purified using distillation and evaporation processes. In this method, metals are vaporized and then condensed at lower temperatures to return to a solid state, achieving purification.

۵. CONVERSION TO INGOTS

After purification, the precious metals are poured into specific molds to form ingots. The ingots are typically produced in various sizes and weights, depending on market demand and industry standards. At this stage, special attention is paid to controlling the temperature and cooling time of the metals to prevent cracks and bubbles in the ingots, ensuring the highest possible quality.

۶. QUALITY CONTROL AND PACKAGING

After the ingots are produced, each one is inspected for purity and quality. This may involve chemical and physical tests to ensure the ingots meet the required standards. The ingots are then marked with their weight and purity and packaged for sale or use in other industries.

Advantages of Converting Precious Metals into Ingots:

*Easier Transportation and Storage: Ingots are easier to transport and store due to their standardized shape.

*Marketability: Precious metal ingots are recognized as standard trading units in global markets, making them easier to buy and sell.

*Value Storage: Ingots are considered an effective method for storing value and investing in precious metals

Refining and purification of precious metals, including gold, silver, platinum, rhodium, and other similar metals, is a complex process aimed at separating these metals from impurities to obtain pure metal. These processes have been in use since ancient times, and with technological advancements, they have gradually improved over time.

۱.Gold Refining

Gold is one of the most important precious metals, and due to its high value, its refining processes require great precision. There are various methods for refining gold, including:

Cyanidation Process: One of the most common methods for extracting and
refining gold is the use of a cyanide solution. In this process, gold ore is combined
with a cyanide solution, dissolving the gold into the solution, which is then
recovered using zinc or activated carbon.

Cupellation Method: In this method, gold and other precious metals are separated
from impurities through heating and the use of oxidizing agents. This method is
particularly used for gold that contains a lot of impurities.

۲.Silver Refining:

Silver, like gold, has been used since ancient times for making jewelry and coins. The silver refining process involves the following steps: Electrolysis Method: In this method, silver is placed in an electrolytic cell, and pure silver is deposited on the cathode by passing an electric current. Due to its high precision, this method is used to produce silver with very high purity. Cupellation Method: Similar to gold refining, this method involves melting silver along with oxidizing agents to separate the impurities.

۳.Platinum Refining:

Platinum is another precious metal widely used in industry and jewelry making. Platinum
refining usually involves the following steps:
Aqua Regia Method: This method involves dissolving platinum in a mixture of nitric acid
and hydrochloric acid. Platinum is dissolved as chloroplatinate, which is then recovered
as pure platinum using other chemical methods.
Chlorination Process: In this method, platinum is converted into platinum chloride, which
is then reduced to pure platinum using heat and appropriate chemicals.

۴.Rhodium Refining

Rhodium is a rare and extremely valuable metal that, due to its unique physical and chemical properties, is used in the automotive industry and jewelry making. The rhodium refining process includes: Dissolution in Specific Acids: Rhodium is typically obtained by dissolving it in sulfuric or nitric acid and then undergoing chemical purification steps. Electrolysis Method: Similar to silver refining, electrolysis is also used in this method to separate pure rhodium from impurities.

۵.Refining Other Precious Metals:

Other precious metals, such as palladium, iridium, and osmium, also have similar refining methods, which are chosen based on the chemical and physical properties of these metals.

۱.Gold Ore Extraction

Mining: Gold-bearing rocks are extracted from mines. This stage involves drilling, crushing, and transporting the rocks to the processing plant.

Choosing the Extraction Method: Depending on the type of rock and mining conditions, various methods such as open-pit or underground mining are selected.

۲. Crushing and Grinding

Crushing the Rocks: The extracted rocks are crushed and ground in industrial mills to be converted into smaller particles.

Ball Mill: In this stage, a ball mill is used for further grinding and preparation for gold separation.

۳. Gold Separation

Flotation: The crushed materials are mixed with specific chemicals that cause gold particles to attach to the surface of the water.

Cyanidation: This is a common method of gold extraction in which gold is separated from the rocks using a cyanide solution.

Carbon in Pulp (CIP) or Carbon in Leach (CIL): In these methods, gold is absorbed from the cyanide solution by activated carbon and then separated from it.

۴. Concentration and Melting Gold Concentration: The separated gold is concentrated using physical and chemical methods, and impurities are removed from it. Melting: Gold is melted in industrial furnaces and formed into bars or pellets, with impurities being removed.

5. Gold Refining Chlorination: In this method, gold is converted to gold chloride and separated from impurities. Electrowinning: In this stage, gold is extracted from chemical solutions using electric current, resulting in purer gold.

6. Casting and Bar Production Casting: The pure melted gold is poured into special molds to form bars. Weighing and Stamping: The produced bars are weighed and stamped before being offered to the market. Laboratories: The quality and purity of the produced gold are examined in specialized laboratories. Packaging: The gold bars are packaged and offered for sale and distribution in the market.
