Nickel Ore Production Line and Process Solution

I. Overview of nickel ore beneficiation process

Nickel ore beneficiation mainly focuses on two types of copper nickel sulfide ore and nickel oxide ore, through the scientific nickel ore beneficiation process design to achieve efficient recovery of nickel resources. This nickel ore beneficiation program provides a complete nickel ore production line configuration proposal, covering crushing, grinding, flotation, dewatering and other key processes.

Second, the core process

1. Crushing and screening system

• Coarse crushing: Jaw crusher

• Medium Crushing: Cone Crusher

• Fine crushing: cone crusher + vibrating screen (closed loop)

2. Grinding and Classifying System

• One-stage grinding: ball mill + spiral classifier

• Second stage grinding: ball mill + cyclone unit

3. flotation separation system

(1) Mixed flotation process

• Applicable: low copper-nickel ore (Cu/Ni<1)

• Flow: primary rougher -secondary fine -secondary sweeping

(2) Priority flotation process

• Applicable: high copper-nickel ore (Cu/Ni>1)

• Flow: Priority flotation for copper - flotation for nickel - separate separation

4. Concentrate dewatering system

• Concentration: High-efficiency thickener

• Filtration: ceramic filter/plate and frame filter press

• Drying: rotary drying kiln (optional)

III. Selection of key equipment for nickel production line

Fourth, the advantages of the process program

1. Flexible adaptation: according to the nature of the ore to choose mixed flotation or preferential flotation

2. High-efficiency recovery: nickel recovery rate can reach 85%-92%.

3. Energy-saving design: adopt stage grinding to reduce energy consumption.

4. Intelligent control: key processes are equipped with automatic control system

V. Technical Service Support

1. Ore test: provide ore dressing test and process validation

2. Engineering design: customized nickel production line layout plan

3. Equipment supply: provide a full set of nickel ore dressing equipment.

4. Installation and commissioning: professional technical team on-site service

Note: Specific nickel ore production line and process solution parameters need to be determined according to the nature of the ore test, it is recommended that the first beneficiation test study.
