CIP,CIL Gold processing plant
In the processing of hard rock gold deposits in Sudan—primarily vein-type or quartz-vein gold ores—the "coarse crushing + fine grinding + gravity separation" workflow stands as the most stable and highest-ROI process available. Baichy Heavy Industry recommends a specific equipment combination tailored for Sudanese gold mine operators: the PE Jaw Crusher, the Model 1500 Wet Pan Mill (Gold Grinding Machine), and the 6-S Shaking Table. This integrated system effectively processes hard quartz rock and facilitates the rapid enrichment of gold concentrates.
I. Analysis of the Core Process Flow
1. Jaw Crusher: The "Vanguard" of Hard Rock Processing
Primary Jaw Crusher
Gold ores in Sudan typically consist of high-hardness quartz veins. Feeding these ores directly into the grinding stage would result in low efficiency and severe equipment wear.
• Function: Rapidly crushes large blocks of gold ore (up to 500mm) into finer particles (down to 10mm).
• Advantages: Baichy’s PE series Jaw Crushers feature high-manganese steel liners specifically designed for hard rock applications. This design significantly reduces the feed load on the subsequent Wet Pan Mill, boosting the overall production capacity of the processing line by over 30%.
2. Model 1500 Wet Pan Mill: The "Miracle Machine" for Gold Extraction in Sudan
In Sudan, the Model 1500 Wet Pan Mill has earned the nickname "Miracle Machine" due to its simple structure and high recovery rates.
Model 1500 Wet Pan Mill
• Technical Specifications: Features a wheel diameter of 1500mm and is equipped with a high-power electric motor.
• Core Function: Achieves the liberation (dissociation) of inpidual gold particles from the ore matrix through a combined process of crushing and kneading.
Sudan-Specific Design: Baichy’s Model 1500 Wet Pan Mill features a reinforced base plate and grinding wheels, enabling it to withstand the high-intensity operations required in Sudan’s high-temperature environment. It serves not merely as a grinding device; during the milling process, mercury can be added to facilitate preliminary gold recovery (amalgamation), making it an ideal solution for artisanal and small-scale miners.
3. 6-S Shaking Table: Precisely Capturing Every Gram of Gold
Following processing in the Wet Pan Mill, the resulting ore slurry is fed onto the Shaking Table to separate the gold concentrate from the waste rock (gangue).
6-S Shaking Table
• Working Principle: Utilizes the specific gravity difference between gold and the gangue minerals to achieve stratification (separation into layers) through the reciprocating motion of the table deck.
• Performance: Baichy Shaking Tables boast an exceptionally high enrichment ratio, enabling the one-step recovery of high-grade gold concentrates. Furthermore, they are simple to operate, require no chemical reagents, and are environmentally friendly.
II. Why Do Sudanese Mine Owners Prefer the Model 1500 Wet Pan Mill?
In Sudan's gold mining regions (such as Abu Hamad and surrounding areas), the Model 1500 is the most sought-after unit:
• Moderate Capacity: The hourly processing throughput of a single unit effectively meets the needs of most small to medium-sized mine owners.
• Easy Maintenance: Featuring a simple structure, the machine can be easily repaired by local Sudanese technicians without the need for complex spare parts.
• Versatility: It integrates crushing, mixing, and purification processes into a single unit.
III. Frequently Asked Questions (FAQ)
Q: How many tons of ore can this equipment process per hour?
A: The processing capacity depends on the specific equipment configuration. Typically, a single Model 1500 Wet Pan Mill paired with a PE Jaw Crusher can achieve a daily processing capacity of approximately 10–15 tons. If higher output is required, multiple wet pan mills can be operated in parallel.
Q: Do the liners in the Jaw Crusher wear out quickly when processing hard quartz vein ores?
A: Baichy Heavy Industry utilizes a specialized high-manganese alloy material that has undergone heat treatment specifically designed to withstand Sudan's hard rock conditions. This extends the service life of the liners by 20%–40% compared to those from standard manufacturers.
Q: Does Baichy Heavy Industry provide service support in Sudan?
A: We possess extensive experience serving the African market. We offer remote video guidance for installation and maintain a year-round stock of wear parts (such as wet pan mill liners, grinding rollers, and jaw crusher liners) to ensure uninterrupted equipment operation.
