    An ore sorter is a specialized machine used in the mining industry to separate valuable ore from impurities. Utilizing techniques such as sensors, cameras, and automated sorting algorithms, it efficiently identifies and separates different types of ore based on their physical and chemical properties. This technology significantly improves the efficiency of the mining process by reducing the amount of impurities that need processing and increasing the concentration of valuable ore. Ore sorters can ensure increased productivity and cost-effectiveness in the mining industry.   Types of Ore Sorters   1. Color Ore Sorter Utilizes color recognition technology to distinguish between different minerals based on their color properties. This sorter is effective in quickly identifying and separating ore particles.   2. AI Intelligent Sorting Machine Harnesses the power of artificial intelligence to analyze and categorize ore based on predefined parameters. This cutting-edge technology enhances the sorting accuracy and efficiency.   3. X-ray Intelligent Sorter  Employs X-ray technology to penetrate and analyze ore particles. This sorter is particularly useful in identifying and separating minerals with distinct X-ray absorption characteristics.   4. Mineral Sand Sorter Specialized for sorting mineral sands, this machine efficiently separates valuable minerals from the surrounding waste based on their unique physical properties.   5. Ultraviolet-ray Sorter Utilizes ultraviolet rays to detect and classify ore particles. This sorter is effective in identifying minerals that exhibit specific UV light interactions.   6. Infrared Sorter Operates by analyzing the infrared spectrum of ore particles, allowing for the separation of valuable minerals from waste based on their unique infrared signatures.   Working Principle of Optical Ore Sorter   Material Illumination Ore particles are illuminated using various light sources such as visible light, X-ray, ultraviolet-ray, or infrared light.   Optical Sensors Specialized sensors capture the reflected or transmitted light from the illuminated particles.   Spectral Analysis The optical system analyzes the spectrum of light interacting with each particle, identifying distinctive spectral patterns associated with different minerals.   Algorithmic Processing Advanced algorithms process the gathered optical data, making rapid decisions about the nature of each particle, distinguishing between valuable and waste materials.   Sorting Mechanism  Based on the analysis, a sorting mechanism is activated to separate valuable ore from waste material, ensuring efficient processing.   Real-time Operation The entire process occurs in real time, allowing for quick and precise separation of valuable minerals from non-valuable ones.   Advantages of Ore Sorting Technology   1. Increased Efficiency By separating valuable rocks from waste before entering the mill, ore sorters improve overall milling efficiency, reducing the need for energy-intensive grinding.   2. Environmental Benefits Reduced waste generation, including tailings, minimizes the environmental impact of mining operations. Lower water consumption contributes to sustainable mining practices.   3. Improved Product Quality  Ore sorting removes low-grade or contaminated rocks, resulting in higher average ore quality and increased yields of valuable metals in the final product.   4. Cost Savings Reduced milling costs are achieved by processing a higher average ore grade and less waste material, leading to significant savings for mining companies.   5. Increased Resource Utilization Ore sorting allows for the extraction of valuable metals from previously uneconomic ore deposits, enhancing resource utilization and overall production.
  • Photoelectric sorting - help to enrich gold grade, enhance economic mining value! Oct 29, 2022
    Gold ore from the major classification is mainly for the vein gold deposits and alluvial gold deposits two types, which vein gold ore is the main case of internal geological action, mainly by volcanic, magmatic, geological action to form; alluvial gold deposits mainly by the mountain gold ore exposed in the ground, after long-term weathering, exfoliation, broken into gold sand, gold particles, gold flakes, gold froth, in the wind and water transport action gathered, deposited in the river, lake, coast, the formation of flood type, alluvial type or Coastal type alluvial gold deposits; There is another part after weathering and denudation, forming residual type alluvial gold deposits or slope accumulation type alluvial gold deposits, this kind of ore formation is generally more long time. According to the associated situation of China's gold ore types can also be divided into gold quartz veins, gold pyrite quartz veins, gold pyrite alteration granite, gold polymetallic sulphide ore vein type, gold oxide ore vein type and gold tungsten arsenic ore vein type.   Vein gold ore industrial mining grade generally in 3 ~ 5 g / ton, border grade 1 ~ 2 g / ton, alluvial gold in 0.2 ~ 0.3 g / cubic meter, border grade 0.05 ~ 0.1 g / cubic meter, but the current stage of mining gold ore in China mainly to vein gold deposits, accounting for about 75% ~ 85%.   At this stage, gold ore is widely used in jewelry, industrial, high-tech industries, etc. Because of its scarcity and non-renewable, the overall value is high. At this stage, gold ore beneficiation methods are mainly divided into four kinds: heavy separation method, flotation method , chemical separation method, and photoelectric separation method.   The re-election method is suitable for coarse-grained gold recovery, and generally belongs to the auxiliary process in gold ore beneficiation, placed in flotation or chemical sorting before as pre-selection process.   Flotation method is mainly widely used in rock deposits, the process has suction type or inflatable agitation type flotation machine for flotation.   Chemical separation method mainly has amalgamation and chlorination method, amalgamation method is mainly applicable to coarse grain monomer gold applicable, but because of its pollution, gradually be replaced, chlorination method mainly has two kinds of stirring chlorination and percolation chlorination.   The above three sorting are conventional gold ore sorting, with economic mining grade or higher than the industrial grade of gold ore, sorting cost is lower than the economic cost, but the general situation of China's gold ore rich ore less poor ore more; mining difficulty, easy to mine less difficult to mine more, most of the gold ore grade is less than 2 g / ton, belong to or lower than the critical mining grade, using the above way directly sorting, more gold ore sorting will appear below the economic mining Value.   Photoelectric sorting method grasps the pain and difficulty of domestic gold ore sorting, and uses artificial intelligence + photoelectric sorting means to enrich gold ore by pre-throwing waste to achieve higher economic mining grade, which solves the problem of low grade and high sorting cost of domestic gold ore. The working principle is mainly to crush and dissociate the original gold ore, after the artificial intelligence sorting machine to establish a multi-dimensional model of the ore, the use of AI photoelectric sorting machine technology to identify the texture, color, luster, shape, reflectivity and other comprehensive characteristics of the gold ore surface differences, after the industrial computer with artificial intelligence technology to sort out the gold ore concentrate and waste rock, so as to achieve the purpose of gold enrichment.     After the artificial intelligence ore sorting machine of the original ore, the ore particle size requirements, only the normal crushing and dissociation, particle size in 0.5cm-10cm, size with the selected particle size in 3-4 times, can be directly sorted enrichment, which throw waste tailings can be used as various types of construction, mine backfill and other materials. After the enrichment of gold ore after flotation or chemical separation method, sorting out the gold ore, pre-throwing waste reduces the processing level of the original ore, saving the processing cost of the subsequent processes.   For some gold ore below the economic mining grade, through the artificial intelligence ore sorter, can be enriched to reach the economic mining grade, enhance the use value of a large number of low-grade gold ore mine, artificial intelligence sorter is not only able to sort gold ore, for gold ore associated ore, as long as it can be broken and dissociated, can use artificial intelligence machine for sorting, enhance the comprehensive utilization rate of the mine, at the same time artificial intelligence sorter equipment The cost itself     Mingde photoelectric artificial intelligence ore sorting machine, for gold ore sorting has mature technology accumulation, can enrich gold ore under the premise of pre-throw waste tailings, and throw waste tailings gold grade is much lower than the economic mining grade.
