Products Description

In Gold CIL (carbon in leach) Processing Plant, activated carbon acts like a sponge to aurocyanide and other complex ions in solution. Hard carbon particles (much larger than the ore particle sizes) can be mixed with the ore and cyanide solution mixture. The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in solution. Because the carbon particles are much larger than the ore particles, the coarse carbon can then be separated from the slurry by screening using a wire mesh.

Working Principle of Gold CIL Plant

CIL is cyanide gold extraction process. Firstly, raw material is crushed into less than 10mm by different types of crushers; secondly, crushed material will be ground and classified into 90% of 200mesh, then fine powder will get into thickner, after concentration, add chemical and leach in the leaching tank. After leaching, we can use activated carbon to adsorb gold, then get gold loaded carbon. Finally we can use electrolysis equipment or fire to get gold bar.Raw material from powder silo will be sent to first ball mill by feeder and belt conveyor, ball mill discharges to spiral classifier, bigger size will be returned back for re-grinding. Overflow will be pumped to hydro cyclone by slurry pump for second classifier: bigger size will go to second ball mill, and the discharges are returned to the second classifier. It is named two steps two closed circle grinding flow chart. Overflow from hydro cyclone will be sent to trash screen and thickener.

Flow Chart of CIL Gold Processing Plant

A. Raw materials preparation:Raw ores are sent to primary crusher by vibrating feeder, then sent to the secondary crusher by belt conveyor; the crushed ores will be sent to vibrating screen for separating. Under screen ores will be sent to powder silo. Upper screen ores will be sent to tertiary crusher by belt conveyor for re-crushing, and the crusher ores will be sent to the screen again to be separated. It is named three step one closed circle crushing flow chart.

B. Leaching and adsorption:The slurry will enter into 8 sets of double impeller leaching tank; well-mixed sodium cyanide agents are added to the first tank; active carbon is added to the tanks from the second to the eighth; active carbon from the second agitator is lifted to carbon screen to get gold-loaded carbon, and after cleaning, the gold-loaded carbon enters into the desorption&electrolysis system; while the slurry left goes back to the second tank; active carbon is lifted by air lifter from the tank next to the tank before against the current; the tailing goes through safety screen to recycle fine-size gold-loaded carbon, and then goes to tail water treatment stage.

C. Tail water treatment:The tailings are lifted to the filter press, and the filter cake is so called tailings, which are transported by belt conveyor and truck to the yard, while filter liquor goes to circulating water tank for recycling, which helps save the lime and sodium cyanide.

D. Gold-loaded carbon treatment:The gold-loaded carbon is processed by Desorption&Electrolysis equipment in batches to get gold-dust. The gold-dust goes to gold melting furnace and turns to gold bar. The gold-loaded carbon after Electrolysis process could return to last stage in the flow chart for reprocessing.

1. What is the Gold Mill Gold Processing Plant?

The Gold Mill Gold Processing Plant is a facility designed for the extraction of gold from ore using the Carbon in Leach (CIL) process, where activated carbon is used to adsorb gold and other complex ions from a cyanide solution.

2. How does the CIL process work?

The CIL process involves crushing raw materials into smaller sizes, grinding them, and then leaching them with cyanide in a series of leaching tanks. Activated carbon is added to adsorb the gold, which is then recovered through electrolysis or fire.

3. What type of raw materials can be processed?

The Gold Mill Gold Processing Plant is designed to process various types of gold ores that can be crushed and ground into fine particles for effective leaching and gold recovery.

4. What are the main components of the plant?

The main components of the Gold Mill Gold Processing Plant include crushers, ball mills, spiral classifiers, hydrocyclones, leaching tanks, activated carbon systems, and electrolysis equipment.

5. Is the process environmentally friendly?

The plant incorporates tail water treatment and recycling systems to minimize environmental impact, allowing for the recycling of water and reducing the need for chemicals like lime and sodium cyanide.

6. How long does the gold recovery process take?

The duration of the gold recovery process can vary based on the ore type and processing conditions but typically includes several hours to days for leaching and adsorption, followed by gold recovery.

7. What safety measures are in place for handling cyanide?

The plant is equipped with safety systems, including proper containment, monitoring of cyanide levels, and training for staff on safe handling procedures to minimize risks associated with cyanide use.

8. Can the plant be customized for specific processing needs?

Yes, the Gold Mill Gold Processing Plant can be customized to meet specific processing requirements, including modifications to equipment and flow chart design based on the characteristics of the ore.

9. What is the capacity of the Gold Mill Gold Processing Plant?

The capacity of the Gold Mill Gold Processing Plant varies based on its configuration, but it is designed to handle a substantial amount of ore efficiently, often measured in tons per hour.

10. What type of maintenance is required for the plant?

Regular maintenance is required for all equipment, including inspections, cleaning, and parts replacement to ensure optimal performance and longevity of the Gold Processing Plant.

11. What are the benefits of using activated carbon in the process?

Activated carbon efficiently adsorbs gold from the cyanide solution, allowing for higher recovery rates and the ability to reuse the carbon in multiple cycles, leading to cost savings.

12. Is training provided for operating the Gold Mill Gold Processing Plant?

Yes, comprehensive training is typically provided for operators and staff to ensure safe and efficient operation of the Gold Processing Plant.

13. How is the gold extracted once it is adsorbed onto the carbon?

Once gold is adsorbed onto the activated carbon, it is processed through a desorption and electrolysis system to separate the gold from the carbon, resulting in gold dust that can be melted into bars.

14. What happens to the tailings after processing?

The tailings are transported to the yard as filter cake, while the filter liquor is recycled for further use in the plant, reducing waste and environmental impact.

15. What kind of support is available after purchasing the plant?

After purchasing the Gold Mill Gold Processing Plant, customers typically receive ongoing technical support, maintenance assistance, and access to spare parts as needed.
