Obote Ore Dry Separation Equipment Helps Solid Waste Resource Conversion

Release time: 2025-08-05

The traditional treatment of solid waste such as coal gangue, tailings, and other solid waste often faces core challenges such as low sorting efficiency, high water consumption, and difficulty in recovering valuable components. Although wet beneficiation is commonly used, the high water consumption and sludge disposal costs are particularly prominent in arid mining areas. Conventional dry sorting technology lacks the precision needed to separate useful minerals from fine particles, leading to resource waste.

Obote’s intelligent dry sorting equipment for non-metallic minerals, based on its magnetic separation technology innovation, is key to overcoming these challenges. The core of this technology is the deep coupling of high-intensity magnetic separation with an intelligent pre-sorting system. By using front-end intelligent identification and pre-sorting, large amounts of non-magnetic waste rock are removed in advance, greatly reducing the load on subsequent magnetic separation. The back-end employs optimized high-gradient magnetic separation or rare-earth permanent magnet drum technology, efficiently and accurately capturing weakly magnetic minerals such as coal-series kaolin and iron minerals from coal gangue. The entire process requires no water, significantly reducing energy consumption and environmental pressure.

Intelligent Pre-sorting + Precise Magnetic Separation: Core Technology Drives Efficient Recovery

The core “intelligence” of Obote’s ore sorting equipment lies in its pre-sorting system, which can quickly analyze and sort materials based on their physical properties (such as particle size, density, and initial magnetic induction intensity). For example, for coal gangue, the following methods can be used:

  • Intelligent Prediction: The system rapidly identifies large waste rocks or low-value components and diverts them in advance, ensuring that the core magnetic separation unit processes a material flow rich in target minerals.
  • Magnetic Purification: For the material after pre-sorting, the equipment’s efficient magnetic separation module generates a strong magnetic field to accurately separate coal-series kaolin from coal gangue, while also effectively separating other valuable associated minerals such as pyrite and siderite.
  • Dry Processing Advantage: The entire process operates dry, avoiding the challenges of tailings pond expansion and wastewater treatment, particularly suited to water-scarce regions and the fine reprocessing of existing tailings.

Resource Recycling and Green Mining:

Obote’s dry sorting technology effectively promotes the transition of the mining industry from a linear extraction-waste model to a closed-loop system of resources-products-regenerated resources. This significantly improves resource utilization, reduces solid waste emissions, and aligns with national green mining construction and the development requirements of “waste-free cities.”

Obote’s intelligent dry sorting equipment, with its innovative intelligent pre-sorting and efficient magnetic separation technology, is providing solid support for the high-value, large-scale utilization of coal gangue, tailings, and other solid waste. It not only represents cutting-edge magnetic separation technology but also injects strong technological momentum into the green and low-carbon transformation of industries such as mining, energy, and building materials. It truly practices the sustainable development path of “turning stone into gold, turning waste into treasure.” As global demands for comprehensive resource utilization continue to rise, such green intelligent sorting technologies are set to have a broader application.
