100t per day capacity copper ore processing plant

In the copper mining process, production techniques and mining equipment are crucial With years of technical expertise and innovation, Henan Zhengkuang Machinery Co., Ltd.'s developed and produced mineral processing equipment has demonstrated outstanding performance in the copper mining sector, solving challenges for numerous companies and becoming highly favored equipment in the industry. 

 1. Crushing Stage (Crushing raw ore to the grindability required for grinding) 

 1.1 Jaw Crusher: As a coarse crushing equipment, it processes raw ore (typically with an input particle size ≤600mm), crushing it down to 100-200mm. 

 1.2. Cone Crusher/Impact Crusher: As a medium crushing equipment, it further crushes the coarsely crushed ore to 20-30mm, meeting the grinding feed requirements (small production lines can also use jaw crushers directly for medium crushing).

2. Grinding stage (grind the ore until mineral single bodies are separated) 

 2.1 Ball Mill: A core grinding equipment, typically selected in specifications of Φ1.83×4.5m or Φ2.2×7.5m, used in conjunction with grading equipment to achieve "closed-circuit grinding," grinding ore to a fineness of -200 mesh with a content of 60%-80% (common fineness for copper ore). 

 2.2. Spiral Classifier/Hydrocyclone: A grading device used to separate coarse and fine particles after grinding. Coarse particles return to the ball mill for further grinding, while fine particles proceed to the separation stage, ensuring efficient grinding performance. 

 3. Sorting Stage (Extracting Copper Minerals, Commonly Using Flotation Method) 

 3.1 Flotation Machine: The core separation equipment, which uses reagents such as yellow pyrite and foaming agents to attach copper minerals to air bubbles, forming foam products (copper concentrate). Commonly used models include XCF/KYF type (aeration agitation type, suitable for small to medium-sized production lines). 

 3.2. Mixing Tank: Includes "Pulp Mixing Tank" (for evenly mixing ground ore pulp with reagents) and "Pre-Flotation Mixing Tank" (to ensure thorough interaction between reagents and minerals), sized to match flotation machines. 

 3.3. Grading Equipment (Auxiliary): If the ore contains a high amount of mud, it's necessary to add a "Dewatering Hopper" or "Hydraulic Cyclone" to prevent fine mud from affecting flotation efficiency.

4. Dehydration Stage (Reduce Copper Ore Concentrate Moisture for Easy Transport/Storage) 

 4.1. Filter: Commonly used "Cabin-type filter press" or "disc vacuum filter press" is used to dehydrate the flotation copper concentrate slurry (with a moisture content of about 30%-40%) to a moisture content ≤15% (industrial qualified concentrate moisture standard).

 4.2 Concentrator: If the slurry moisture content is too high, you can add a "High-Efficiency Concentrator" before filtration to first concentrate the slurry to about 50% moisture content, reducing the load on the filtration machine.

5. Auxiliary Equipment 

 5.1 Feeding Equipment: Such as "Vibratory Feeders" (for uniform feeding of ore to the crusher) and "Belt Scales" (for metering raw ore processing volume). 

 5.2. Conveying Equipment: "Belt Conveyor" (connecting various equipment links to transport ore/ore slurry), "Slurry Pump" (for transporting slurry). 

 5.3 Pharmaceutical Preparation Equipment: "Pharmaceutical Dissolution Tank" and "Pharmaceutical Mixing Tank" (for preparing solid pharmaceuticals into liquid pharmaceuticals of specified concentrations).
