TYPICAL Mineral Processing Cases You Want to Know

Here we will give a breif introduction to typical mineral processing solutions we have carried out before. Each case will be explained with ore property, customized process, main machines and final results.
Hope you can find the typical mineral processing plant you want to know.

01 - China 4400TPD Copper Processing Plant

• Ore Properties

  The raw ore was high-sulfur Cu-S ore in the form of dense lump. Cu, S and Fe were closely associated. With Cu minerals being fine, the ore was of hard beneficiation.

• Customized Solution

  Flotation process of one-stage roughing, two-stage scavenging and three-stage concentration

• Main Equipment

  XCF Air Inflation Flotation Cell, KYF Air Inflation Flotation Cell, Overflow Type Ball Mill, Jaw Crusher, Magnetic Separator

• Project Results

  The final products were sulfur concentrates and copper concentrates. Comprehensive analysis showed that the project was relatively lucrative. The project fully tapped into the mineral resources and ensured environmental protection through solid waste recycling.

02 - China 3000TPD Lead-Zinc Tailings Dry Stacking Plant

• Ore Properties

  Lead and zinc are the main minerals.

• Customized Solution

  Flotation tailings adopted dewatering cyclone-dewatering screen-thickener-filter press.

• Main Equipment

  Hydrocyclone Unit, Press Filter, High Frequency Dewatering Screen, Efficient Thickener, Energy Saving Ball Mill

• Project Results

  The final water content of tailings dry stacking was lower than 15%. The service life of whole production line was twice as long as the common production line, which greatly reduced the artificial maintenance, and the operating costs were saved more than 2 yuan/ton at least.

03 - Pakistan 1500TPD Copper Processing Plant

• Ore Properties

  The raw ore was characterized by simple composition. It consisted of metallic minerals (copper pyrite and pyrite) and non-metallic minerals (quartz and chlorite). The Cu grade of the raw ore was 0.80%.

• Customized Solution

  Two- and half-stage closed-circuit crushing-one-stage closed-circuit grinding-flotation process of one-stage roughing, two-stage scavenging and two-stage concentration-two-stage mechanical dewatering

• Main Equipment

  Hydrocyclone, Press Filter, SF Flotation Cell, Overflow Type Ball Mill, Spring Cone Crusher

• Project Results

  The grade of copper concentrate was 20.78%, and the recovery rate of copper was up to 90.05%.

04 - Nigeria 1000TPD Gold-Copper Processing Plant

• Ore Properties

  Copper and gold are the main minerals.

• Customized Solution

  Two-stage semi-closed circuit crushing-continuous two-stage closed-circuit grinding-flotation process of one-stage roughing, three-stage scavenging and four-stage concentration-two-stage mechanical dewatering

• Main Equipment

  Efficient Improved Thickener, KYF Air Inflation Flotation Cell, Grid Type Ball Mill, Jaw Crusher

• Project Results

  After the raw ore was ground to -0.074mm (90%), copper concentrates were produced through the flotation process of one-stage roughing, three-stage scavenging and four-stage concentration. The concentrates had a Cu grade of 20.23%, a Cu recovery of 74.35%, an Au grade of 4.41g/t, an Au recovery of 75.66%, an Ag grade of 3,526.63g/t and an Ag recovery of 81.81%.

05 - Iran 500TPD Lead-Zinc Flotation Plant

• Ore Properties

  The raw ore of this project contained 3.68% of lead, 2.85% of lead in lead oxide, and 77.45% of lead oxidation; 16.06% of zinc, 15.93% of zinc in zinc oxide, and 99.20% of zinc oxidation.

• Customized Solution

  Two stage and one closed circuit crushing and screening - two stage closed circuit grinding - lead flotation (two roughing, one sweeping and four refining) - zinc flotation (two roughing, two sweeping and four refining) - dewatering process of lead and zinc concentrate.

• Main Equipment

  Hydrocyclone Unit, Efficient Thickener, Leaching Agitation Tank, KYF Air Inflation Flotation Cell, Overflow Type Ball Mill, Jaw Crusher

• Project Results

  The final products were lead concentrate and zinc concentrate. The grade of lead concentrate and zinc concentrate was 41.03% and 42.85% respectively.
