Project Overview
The MAZONGSHAN Gold Mine, located in Jiuquan City, Gansu Province, China, has successfully established an 800 tons per day (TPD) carbon pulp processing plant. The primary objective of the project was to efficiently process sulfide gold ore extracted from underground mining operations, using the carbon-in-pulp (CIP) technology to maximize gold recovery.
Ore Characteristics
- Mining Method: Underground (cave) mining
- Ore Type: Sulfide ore
- Average Gold Grade: 2.7 grams per ton (g/t)
Processing Technology
The processing plant employs the carbon-in-pulp (CIP) method, which is well-suited for treating gold-bearing ores with relatively fine gold particles. The process involves the leaching of gold from ore with a cyanide solution, followed by adsorption onto activated carbon.
Operational Parameters
- Plant Capacity: 800 tons of raw ore per day
- Leaching Time: 48 hours
- Alkali Value (pH): Maintained between 9 and 10
- Reagent Consumption: 700 grams of reagents per ton of ore
Technical Performance
The plant has demonstrated high operational efficiency and process effectiveness, achieving the following key performance indicators:
| Parameter | Value |
|---|---|
| Gold Leaching Rate | 93% |
| Carbon Adsorption Rate | 98% |
| Overall Gold Recovery Rate | 91.14% |
Project Significance
This project represents a significant advancement in gold extraction technology in the region. The high recovery rate indicates efficient leaching and adsorption, optimizing both yield and cost-effectiveness. The successful implementation of the carbon-in-pulp process at this scale sets a benchmark for similar sulfide gold ore processing facilities.
Conclusion
The 800 TPD carbon pulp plant at the MAZONGSHAN Gold Mine showcases a well-executed application of CIP technology in processing sulfide gold ore. With a solid recovery rate of over 91%, the project has met its production and efficiency goals, contributing positively to the region’s mining industry and economic development.
