Qalkari Zarin Sanat in Shiraz is known as one of the leading complexes in the field of gold smelting, precious metal recycling and electronic waste processing. This complex offers services that are reliable for both gold workshops and large industries by using Qal, rotary and CNC furnaces and using the knowledge of metal processing engineering. The real efficiency of more than 99% in gold and silver mining is the main distinguishing point of Zarin Sanat.
The importance of recycling and melting precious metals in today's industries
Precious metals such as gold, silver and palladium play a vital role not only in the jewelry industry but also in the electronics, telecommunications, medical and precision equipment industries. A large volume of these metals in waste, electronic boards or even concentrated soils go to the waste cycle. Considering the high price of gold and silver, its recycling is not only an economic activity but also an environmental necessity.
Galkari Zarin Sanat Shiraz uses precise temperature control technology to melt wastes and gold-making soils in a way that results in the lowest losses and the highest efficiency.
Melting of workshop and factory gold mining soils
One of the main services of Zarin Sanat is smelting workshop and factory gold-making soils. The soil obtained from brooms, ventilation filters, polishing stones and even the waste of repairing gold shops, contains significant amounts of precious metal.
In the smelting process with the Qal furnace, the soil is first dried and sieved, then it is combined with special melting materials. Further, by controlling the melting temperature and time, precious metals are separated from impurities and returned in the form of ingots or pellets. This method is implemented in Zarin Sanat Shiraz with a real efficiency of 99% and is trusted by many gold workshops in the south of the country.
Melting of minerals and concentrated soil with a rotary furnace
In the next stage, Zarin Sanat's Galkari has the possibility of smelting all kinds of minerals and concentrated soils containing gold and silver. Concentrated stones that are extracted from mines often contain sulfide compounds and require a precise melting and refining method.
Zarin Sanat using rotary furnace and industrial furnace offers a process that increases the percentage of recovery up to 99% with precise control of the atmosphere. In this method, metals are separated from matte and slag and are provided to the customer in the form of ingots or powder ready for further processing.
Melting of electronic components and computer boards
Used computer and mobile boards are a rich source of valuable metals. Gold is extracted from connections, silver from solder, and palladium from capacitors. Smelting of electronic board and computer parts by Zarin Sanat Shiraz, includes the process of separation, washing, pyrolysis and thermal recycling.
The CNC furnaces used in this collection, with multiple temperature and oxygen controls, separate metals from insulating and plastic materials and minimize losses. All actions are carried out with safety and environmental standards, and recycled metals with very high purity are delivered to the customer.
Pelletizing silver from gold mining soil and workshop waste
After extracting silver from soil or waste, it is time to silver shot, which is one of the most precise services of the industry. In this method, the melted silver is divided into uniform drops through the controlled flow and cooled, and it turns into shiny and pure balls.
The advantage of silver shot is that it is very suitable for use in casting and remelting and allows for uniform mixing with alloys. This service is mainly done and sent to gold workshops all over the country.
Melting and recycling of chemical waste
In the process of gold plating, polishing and washing, residues are produced that contain precious metals. These solutions include sulfate, cyanide, and galvanic deposits. Zarin Sanat Shiraz has an important role in restoring the economic value of these resources by fully covering melting of chemical waste and recycling metals from them.
By controlling thermal and chemical reactions, gold and silver are separated from the solution and in the final stage of melting, pure metal is extracted. All operations are carried out in a fully controlled environment under the supervision of metal experts.
CNC technology in melting precious metals
One of the golden success factors of the industry is the use of precise CNC furnaces. These furnaces allow simultaneous control of temperature, time and oxygen content, which is very vital in the process of melting precious metals.
Using digital data and thermal sensors ensures that the melting temperature is always at the optimal point and no part of the metal burns or oxidizes. In addition to increasing efficiency, this technology also greatly reduces the consumption of energy and chemicals.
The main stages of plating and smelting gold
1. Preparation of soil or waste
At this stage, gold-making soil is sieved and impure particles such as fat and alloy dust are separated. Then it is combined with auxiliary materials to prepare for melting.
2. Melting in the Qal furnace
The furnace is heated to a controlled temperature and the melting process is done gradually. At this stage, the metals are separated from the slag in molten form.
3. Casting and cooling
The melted metal is poured into a special mold and after cooling it turns into ingots or pellets.
4. Final refinement
If higher purity is needed, the ingot or ball is refined again in controlled heat to obtain pure silver or gold.

Methods to ensure 99% efficiency
Zarin Sanat uses several quality control steps to achieve high extraction efficiency:
- Preliminary analysis of soil or ore with XRF device.
- Adjustment of smelting aid compounds based on soil type.
- Instant heat control during the smelting process.
- Precise separation of metal from slag at optimal temperature.
- Comparison of weight before and after smelting to ensure accuracy.
All these steps cause the loss of precious metals to be almost zero.
Environmental responsibility and compliance with standards
Qalkari Zarin Sanat Shiraz carries out its processes considering environmental principles. Controlling vapors, reusing chemicals and recycling metal waste are among the measures that place this complex in the category of green industrial units.
Decreasing energy consumption in each melt and using a smoke filtration system causes the least possible pollution.
Expert advice and cooperation with gold workshops
Zarin Sanat does not limit its services only to smelting; Rather, for workshops and factories that have dirt and waste, the experts of the collection are ready to provide specialized advice. From how to collect and pack the soil to the analysis of grade percentage, all steps are carefully taught so that the customer receives the most return from his waste.
Summary
