This article will analyze the top 7 gold processing equipment solutions in China, covering the complete process from raw ore pretreatment to concentration and dehydration, helping you find the customized solution best suited to your specific mineral deposit characteristics!
7 types of gold processing equipment solutions in China: washing, crushing, screening, grinding and grading, then to core beneficiation processes (gravity separation, flotation, magnetic separation, and CIP/CIL), and concentration and dewatering. We will select the optimal configuration for each process based on your ore characteristics to maximize beneficiation efficiency and return on investment!
Key processes in gold processing
Common gold mineral processing Flows from raw ore to concentrate:
- Washing: Efficient pretreatment for removing mud and impurities
- Crushing: A key step in reducing ore particle size
- Grinding: Enhancing mineral liberation
- Mineral processing: The core process for efficiently enriching gold
- Concentration and dehydration: Concentrate drying and tailings treatment
7 Major Solutions About China Gold Processing Equipment
1. Gold Ore Washing Equipment
Ore washer is a necessary preliminary step in the beneficiation of high-mud gold ore. It is primarily suitable for alluvial/placer gold ore and oxide gold deposits with a mud content exceeding 15%. Through the agitation and scouring action of washing machines, drum screens, and vibrating screens, the mud clumps encasing the gold particles are dislodged, while waste rock and impurities are separated.
Benefits:
This step prevents clogging of subsequent crushing and screening equipment, reduces wear on durable parts, increases the overall ore recovery rate by 5%-8%, and reduces equipment maintenance costs by approximately 10%.
2. Crushing & Screening Equipment
The crushing process typically employs a three-stage closed-loop design: coarse crushing, medium crushing, and fine crushing. Coarse crushing uses a jaw crusher to break the raw ore to below 150mm. Medium and fine crushing are combined with cone crushers (for hard rock gold ore) or impact crushers (for soft rock gold ore).
Screening equipment is usually connected after the crushing stage, primarily to return materials of unqualified particle sizes to the crushing stage for reprocessing.
Function:
The combined crushing and screening equipment controls the feed particle size to below 15mm, significantly reducing energy consumption in subsequent grinding stages. Suitable for gold processing production lines with daily processing capacities ranging from 10 tons to thousands of tons.
3. Grinding & Classification Equipment
Grinding and classification are the core steps in achieving individual gold particle liberation. A combination of ball mills and spiral classifiers or hydrocyclones is typically used to grind the crushed ore to a suitable particle size, ensuring complete separation of gold particles from gangue. If the grinding particle size is too coarse, gold particles will not be liberated, resulting in low recovery rates; if it is too fine, over-grinding will occur, leading to the loss of fine gold particles.
Function:
In actual gold processing plant, the ore is primarily impacted and ground using steel balls or bars to achieve the fineness required for flotation or leaching processes.
China’s JXSC energy-saving ball mill can optimize the grinding media ratio and control the grinding concentration, achieving a liberation rate consistently above 95%, with energy consumption approximately 12% lower than traditional equipment.
4. Gold Separation Equipment
Gold separation equipment is the core component determining the final gold recovery rate and directly affects the final concentrate grade. It mainly employs processes such as gravity separation (e.g., shaking tables, centrifugal concentrators), flotation, or chemical leaching (CIP/CIL), selecting the most suitable enrichment method based on the ore properties.
Function:
Separation (beneficiation) is the core component determining the final gold recovery rate.
Processes can be flexibly selected based on the characteristics of the ore type:
- Coarse-grained placer gold deposits preferentially use gravity separation equipment such as jigs and shaking tables, achieving recovery rates of over 90%.
- Fine-grained disseminated gold deposits use flotation machines to enrich the gold concentrate.
- High-grade, fine-grained gold deposits preferentially use CIP/CIL carbon leaching processes, achieving gold recovery rates of up to 95%.
- For complex associated gold deposits, a combined process of “gravity pre-enrichment + flotation + carbon leaching” can be used to maximize the overall recovery rate.
5. Thickening & Dewatering Equipment
Thickening and dewatering is a crucial final stage that balances environmental protection requirements with cost control. Gold concentrate after mineral processing typically has a high water content and requires solid-liquid separation using equipment such as thickeners, filters, or centrifuges. Water recovery rates can reach over 92%, significantly reducing water consumption in production.
Advantages:
High-efficiency dewatering equipment (such as ceramic filters and plate and frame filter presses) can recover residual fine gold particles from the slurry, reducing the water content of tailings. It also allows for the recycling of some process water, aligning with the development trend of modern green mines.
6. Auxiliary Equipment
Feeding and conveying equipment is fundamental to ensuring the continuous and stable operation of the production line. Among them, the vibrating feeder can automatically adjust the feed rate according to the downstream grinding load, avoiding idling or blockage problems. The belt conveyor uses high-wear-resistant rubber belts with a service life exceeding 3 years. Multi-stage feeding and conveying directions, distances, and layouts are customizable to adapt to the conveying needs of ores and slurries of different particle sizes, covering gold mine production lines of all capacity scales.
7. Melting Equipment
The core function of gold smelting equipment is to smelt gold mud and gold concentrate produced from mineral processing into crude gold ingots on-site, reducing losses and costs during concentrate transportation. China’s JXSC induction melting furnace features rapid heating, low energy consumption, and a gold smelting recovery rate exceeding 99.5%, producing standard gold ingots with a grade of over 99%.
