Silver Ore Beneficiation Production Line and Process Solution

I. Overview of Silver Ore Beneficiation Process

The silver ore beneficiation process mainly adopts flotation method to efficiently recover silver ores of different nature (independent silver ore or associated silver ore). Our silver ore beneficiation production line and process solutions can significantly improve the silver recovery and concentrate grade by optimizing the grinding fineness, adjusting the slurry pH and improving the pharmaceutical system.

Second, silver ore beneficiation process

1. Crushing and screening system

• Raw ore silo: storage of raw ore, to ensure a continuous supply of material

• Metal detector: removing metal impurities in the ore.

• Jaw and Cone Crusher: Crushes the ore to 15-25mm.

• Drive Screen: Screens the qualified size ore into the powder silo.

2. Grinding and Classifying System

• Ball mill: grinds the ore to the appropriate fineness.

• Spiral classifier: to realize coarse and fine particle classification, coarse particles return to regrind.

• Stirring tank: adjusts the concentration of slurry

3. flotation system (core process)

Flotation process configuration:

1. Roughing: rapid recovery of silver minerals with good floatability.

2. Concentration Ⅰ: improve the grade of the rough concentrate

3. Concentrate Ⅱ: further purify the concentrate

4. Sweeping: recovery of residual silver minerals in the tailings

Key technology optimization:

• Stage grinding: rough grinding and mixing roughing → rough concentrate regrinding → concentrating

• Pharmaceutical system: adjusting agent, trapping agent, foaming agent

  •  

   

• Foam control: utilize secondary enrichment to reduce foaming impurities

4. Concentrate processing system

• Concentrator: increase concentrate concentration

• Filter: reduce concentrate moisture

• Smelting: the concentrate is sent to the smelter to extract silver ingots.

5. Tailings treatment system

• Tailings storage: safe storage

• Return water utilization: to realize the recycling of water resources

Third, the silver production line key equipment selection

Advantages of silver ore dressing process and production line program

1. High recovery rate: through the stage grinding and flotation process, the silver recovery rate is improved.

2. Energy saving and consumption reduction: regrinding process saves energy consumption.

3. Flexible and adaptable: it can process all kinds of silver ores (independent silver ore and associated silver ore).

4. Environmental protection: closed design of the whole process, recycling of wastewater.

V. Production Examples

A silver mine transformation case:

• Problems of the original process: low silver recovery rate, low concentrate grade

• Remodeling measures:

  • Adopt new process of stage grinding and floating

  • Optimize the pharmaceutical system

  • Upgrade flotation equipment

• Modification effect:

  • Increased silver recovery

  • Increased concentrate grade

  • Reduced energy consumption
