Chemical Ramat System

Chemical ramat system is a method used to recover precious metals (especially gold and silver) from industrial waste, scrap materials or old electronics. Ramat usually refers to mixed scrap or processed materials containing various metals. This system refers to the process of separating and purifying precious metals with chemicals used during metal refining.

Chemical ramat process is a highly effective method for ensuring maximum metal recovery from waste containing precious metals. A wide range of materials, from electronic devices to jewelry production waste, are processed with chemical processes to recover precious metals.

1. The Importance of the Chemical Waste System
Chemical waste is a very important system in terms of sustainability and economic gain. Especially with the increase in electronic waste, the recovery of precious metals found in these wastes provides great environmental and economic benefits. The recycling of high-cost metals such as gold and silver both protects natural resources and reduces industrial costs.

In addition, the chemical recovery of precious metals found in various sources such as electronic devices, jewelry-making waste materials and dental materials allows the waste to be evaluated and reused.

2. Chemical Ration System Processes
Chemical Ration systems generally include the stages of separating and recovering precious metals from impurities with the help of chemical solutions. The most commonly used methods of this system are:

a. Aqua Regia Method
One of the most commonly used methods in the chemical wastewater system is the Aqua Regia (King's Water) method. Aqua Regia is a strong acid consisting of a mixture of nitric acid and hydrochloric acid. This mixture allows the dissolution of precious metals such as gold and silver. Precious metals in electronic waste are dissolved in the Aqua Regia solution and metal compounds are obtained in liquid form. Then, the precious metals in this solution are precipitated in solid form by reduction and purified.

b. Cyanidation Method
Cyanidation is another chemical method used in the recovery of metals such as gold and silver. In this process, waste materials are treated with cyanide solution to dissolve gold or silver. These metals are then obtained by chemically separating them from the solution. The cyanidation method is an effective method in the recovery of precious metals, especially from low-quality ores or waste. However, the use of this method should be managed carefully due to its environmental risks.

c. Leaching Method from Ore
Leaching is a technique used in chemical leaching systems to dissolve materials containing precious metals. In this method, metals are dissolved with chemical solutions (e.g. cyanide, thiourea or thiosulfate). After this dissolution, metals are precipitated by chemical processes and brought to pure metal form. The leaching method is generally used in the recycling of low-metal scrap.

d. Electrolytic Leaching
Electrolytic leaching is a method used in the purification of precious metals dissolved by chemical processes. In this method, an electric current is passed through the solution containing the metal and the metal ions are deposited on the cathode. The metal purified in this way is recovered in high purity. The electrolytic process is generally used in the recovery of metals such as gold and silver from industrial waste.

3. Chemical Ration System Process Steps
Chemical Ration systems generally include the following process steps:

Raw Material Collection: The first step of the chemical ration process is the collection of scrap, waste materials or electronic devices containing precious metals. These wastes can come from different sources such as electronic circuit boards, dental materials, jewelry waste or industrial waste.

Crushing and Grinding: The collected material is mechanically crushed and ground before the chemical treatment. This step maximizes the effect of the chemical solutions by increasing the metal surface area.

Chemical Dissolution: The ground material is treated with suitable chemical solutions. Precious metals are dissolved using solvents such as Aqua Regia, cyanide, or the leaching method.

Precipitation of Metals: Precious metals are precipitated by adding reducing agents to the solution. In this step, metal ions are separated from the solution and converted to pure metal form.

Purification: The recovered metal is purified by electrolytic methods or other chemical processes if necessary. The purification stage is especially important for industrial applications that require high purity.

Casting and Preparation for Use: The purified metal is converted into a final product in the form of ingots, powder or other forms and offered for commercial or industrial use.

4. Advantages and Challenges of Chemical Ration System
Advantages:
High Recovery Efficiency: Chemical ration methods provide high efficiency in recovering valuable metals. High purity metal can be obtained even from low-quality waste.
Economic Gain: Valuable metal recovery from electronic waste and scrap materials provides significant economic gains. It is less costly compared to the cost of directly extracting metal from natural resources.
Environmental Benefit: Recycling waste contributes to the conservation of natural resources and also has a positive impact on the environment by reducing the amount of waste.
Difficulties:
Environmental Risks: Some chemical methods, such as cyanidation, can produce environmentally hazardous waste. Therefore, such processes should be managed carefully.
High Chemical Consumption: Chemical ration systems may require the use of large amounts of chemicals, which can increase costs and increase environmental impacts.
Special Equipment Requirement: Chemical ration processes usually require special laboratory equipment and safety precautions, which can be difficult for small-scale operations.
5. Conclusion
The chemical waste recycling system is an effective and widely used method for the recovery of precious metals. It allows the economic recovery of precious metals such as gold and silver, especially from electronic waste and industrial scrap. While providing significant benefits in terms of environmental sustainability, it should not be forgotten that the chemicals and processes used must be managed correctly. Chemical waste recycling systems will continue to develop with more environmentally friendly and efficient methods in the future.
