As mineral resources become increasingly depleted, environmental protection requirements become increasingly stringent, and labor costs continue to rise, the efficiency and accuracy of mineral processing directly determine the core competitiveness of mining companies. Traditional mineral processing methods are often inadequate in terms of energy consumption, efficiency, and sorting accuracy. With its cutting-edge optoelectronic intelligent sorting technology, MINGDER Optoelectronics is providing efficient, intelligent, and green solutions to this industry pain point. Choosing MINGDER Optoelectronics means choosing mineral processing competitiveness for the future.

1. Core technology: the “Fiery Eyes”of intelligent sorting

The core advantage of MINGDER Optoelectronics lies in its profound accumulation of optoelectronic recognition and intelligent decision-making technology:

1. High-precision multispectral/hyperspectral sensing: The equipment is equipped with advanced optical sensors that can accurately capture subtle spectral feature differences on the surface and inside of the ore (such as color, texture, mineral composition, impurity distribution, etc.), with a resolution far exceeding traditional manual or mechanical sorting methods.

2. AI-driven intelligent recognition algorithm: Based on the core algorithm of deep learning, it can process massive spectral data in real time and accurately establish a mapping model between ore characteristics and target minerals/impurities. The system has strong self-learning and adaptive capabilities and can cope with natural fluctuations in ore properties.

3. High-speed real-time processing and precise blowing: The powerful data processing platform ensures that when the ore passes through at high speed (the processing capacity can reach tens to hundreds of tons/hour), identification and decision-making are completed instantly, and the high-pressure gas valve array is directed to spray and separate the target particles with millisecond-level precision.

4. Modular and customized design: The equipment adopts modular design. The core optical module, sorting execution module, control module, etc. can be flexibly configured according to different ore characteristics (particle size, density, sorting requirements) to meet the diverse needs from coarse-grained pre-disposal to fine-grained selection.

2. Wide range of application scenarios: full coverage from "extensive" to "fine"

MINGDER Optoelectronics' mineral processing equipment has a wide range of applications and effectively solves the separation problems of various ores:

1. Metal Minerals:

Pre-discarding/pre-enrichment: After crushing and before grinding, low-grade waste rock can be removed efficiently (up to 90% waste rock removal rate), greatly reducing the amount of input and subsequent processing costs (energy consumption, reagents, tailings). Applicable to iron ore, manganese ore, lead-zinc ore, copper ore, tungsten ore, tin ore , gold ore , etc.

Tailings re-selection: Recover valuable minerals from tailings discarded by traditional processes, turning waste into treasure and improving resource utilization.

2. Purification of non-metallic minerals:

Phosphate ore purification and efficiency enhancement: Efficiently pre-enrich the crushed block/granular phosphate ore or remove low-grade intercalated stone and carbonate gangue (such as dolomite, calcite and siliceous minerals) to improve the grade of the selected phosphate ore, reduce the amount of ore in the subsequent flotation process, and reduce the cost of mineral processing and reagent consumption.

High-purification of talc: Accurately capture the subtle spectral differences in color, texture, and mineralogical characteristics of talc and its associated impurities (especially silicate minerals such as tremolite and chlorite). Efficiently remove iron-containing minerals, carbonates, and major silicate impurities to improve the whiteness and purity of talc concentrate.

Dolomite impurity removal optimization: Based on spectral characteristics, the reflective characteristics of dolomite, quartz, flint (siliceous) and iron-containing minerals are clearly distinguished. The crushed dolomite is efficiently sorted to remove siliceous inclusions, flint nodules and iron-containing spots, effectively increasing the MgO/CaO content in the product and reducing the SiO2 and Fe2O3 content.

Deep purification of pegmatite quartz ore: After coarse/medium crushing, a large amount of low-value gangue such as feldspar and mica in the pegmatite can be efficiently removed, reducing the subsequent high-cost ultra-fine crushing and deep purification processing volume.

As well as calcium carbonate removal and whitening, fluorite ore extraction and calcium reduction, potassium and sodium feldspar separation, limestone polishing and refinement, wollastonite refinement, etc.

3. Coal sorting:

Lump coal/granular coal gangue removal: Efficiently remove gangue (gangue recognition rate can reach over 95%), increase calorific value, and reduce ash and sulfur content.

4. Renewable resources sorting:

Scrap metal materials: achieve accurate separation of various types of metal products.

Solid waste resource utilization: sorting specific valuable components.

3. Solve the core pain points of the industry: turn "difficult" into "easy"

MINGDER Optoelectronics Equipment directly addresses many pain points of traditional mineral processing technology and provides revolutionary solutions:

1. Reduce grinding energy consumption and cost:

Pain point: Grinding is the most energy-intensive part of the mineral processing process (accounting for 50-70%), and processing large amounts of waste rock is a huge waste.

Solution: Efficient pre-throwing can significantly reduce the amount of material fed into the mill (up to 30%-70%), directly and significantly reducing grinding power consumption, steel consumption and subsequent processing costs.

2. Improve resource recovery rate and concentrate grade:

Pain points: The recovery rate of complex and difficult-to-select ores (such as fine-grained ores, complex symbiotic relationships, and oxidized ores) is low using traditional methods, and the concentrate grade is difficult to meet the standard.

Solution: Intelligent sorting based on the physical characteristics (non-chemical properties) of ore has unique advantages for fine particles (up to 3mm or even finer) and complex ores, and can significantly improve recovery rate and concentrate quality.

3. Significantly save water resources and achieve green production:

Pain points: Traditional wet mineral processing (gravity separation, flotation, magnetic separation) consumes huge amounts of water (several tons of water per ton of ore), produces a large amount of wastewater containing pharmaceuticals, and puts great pressure on the environmental protection.

Solution: Photoelectric sorting can be physically dry sorted, which consumes almost no water resources and produces no wastewater. It is especially suitable for arid and water-scarce areas or areas with strict environmental protection requirements.

4. Reduce the use of chemical agents and reduce the risk of environmental pollution:

Pain point: Processes such as flotation rely on large amounts of chemical reagents, which pose environmental risks and processing costs.

Solution: Photoelectric separation avoids the use of flotation agents and is more environmentally friendly and safer.

5. Reduce manual dependence and operating costs:

Pain points: Traditional manual selection has low efficiency, high cost, unstable accuracy, high labor intensity, and difficulty in recruiting workers.

Solution: Fully automated operation, 24-hour continuous work, greatly reducing labor requirements and improving sorting efficiency and stability.

6. Shorten the process and improve efficiency:

Pain points: Traditional processes are long, require large investments, and are complex to manage.

Solution: Photoelectric sorting can simplify the process at the front end (such as replacing part of the crushing/screening/re-selection/hand sorting), reduce the overall investment and operational complexity, and quickly achieve results.
