Fluorite: Separates fluorite concentrates for metallurgical and chemical applications, eliminating gangue and other contaminants. Calcite/Calcium Carbonate: Purifies heavy calcium carbonate powder as well as food‑grade and pharmaceutical‑grade calcium carbonate. Barite/Dolomite/Talc: Classified and decontaminated for use in drilling, coatings, and fillers. Kaolin/Coal Gangue: After crushing large raw ore blocks, it is sorted to replace manual picking.   
● Metal Ore Beneficiation:   
Tungsten/Molybdenum ores: Separate scheelite and wolframite from gangue to increase concentrate grade. Gold/Silver ores: Remove waste rock from hard‑rock and placer gold deposits to enhance gold recovery. Hematite/Magnetite/Copper oxide: Sort high‑grade ore blocks by color and texture. Metallic silicon: Separate industrial‑grade and polycrystalline silicon feedstocks, removing impurity particles.   
Architecture/Recycled Resources:   
● Granite/Marble: Raw blocks and crushed stone are sorted to remove discolored or cracked material. Pebbles and wollastonite: used for landscape stones and concrete aggregates, they undergo grading and impurity removal. Glass cullet: recycled glass is cleaned of contaminants and sorted by color to enhance the purity of the reclaimed material.   
● Dry and wet operating conditions:   
Dry separation: 16 mesh to 50 mm (5 cm), suitable for dry ores and water-scarce mining areas in northern regions. Wet separation: 8 mm to 50 mm, ideal for washed ores, moist materials, and rainy mining areas in southern regions. Mixed-material processing: simultaneous sorting of materials with varying particle sizes and mineral types, reducing equipment investment.

V. Core Technological Advantages

1. AI-powered multispectral recognition with accuracy exceeding 99.9%: 5400-pixel high-speed full-color CCD combined with multispectral imaging captures micron‑level color differences, surface textures, and internal impurities. Powered by AI deep‑learning algorithms, it autonomously learns the characteristic signatures of various mineral types, becoming increasingly accurate with use; it supports multi‑dimensional sorting through color selection, shape analysis, and texture discrimination. Sorting accuracy remains stable at ≥99.9%, with false‑reject and false‑accept rates below 0.1%; the carry‑over rate of rejected material is ≤2%, significantly lower than the industry average of 5%.   
2. Double-layer track free-fall, efficient and low-loss: Dual-layer conveyor belt with uniform material distribution combined with high-speed free-fall sorting ensures that materials do not overlap or stick together, achieving precise separation in a single pass. High throughput: each unit processes 3–10 tons per hour for fine sand, 10–35 tons per hour for medium-sized ore, and 30–100 tons per hour for large‑size ore—more than twice the capacity of conventional equipment. Low energy consumption: the entire system consumes only 6.5–10 kW, with overall power usage more than 45% lower than comparable machines.   
3. Wet-and-dry dual use + wide particle size range, with maximum compatibility: One‑button switching between dry and wet modes—no equipment modification required. Wet ores and washed ores can be sorted directly, eliminating the need for drying. With a full particle-size range from 1 mm to 200 mm, it meets the diverse needs of mining operations. Strong anti‑interference: its multispectral technology is unaffected by lighting, dust, or humidity, ensuring stable performance even under challenging operating conditions.   
4. Stable and durable, with low operational maintenance—20 years of sustained value: Key components—including the CCD, pneumatic valves, and tracks—are sourced from leading international brands, ensuring a machine lifespan of 20 years. The self‑purging high‑speed pneumatic valve offers rapid response, low power consumption, and extended service life; dust removal can be performed without shutting down, enabling continuous operation under zero pressure. A modular design facilitates easy disassembly, assembly, and maintenance, while standardized spare parts reduce operations and maintenance costs by more than 50%.   
5. High returns, product enhancement, efficiency improvement, and cost reduction: Increasing concentrate grade: For example, when the purity of quartz sand increases from 90% to 99.9%, the premium can exceed 50%. Improved recovery rates: for gold, tungsten, and other metallic ores, recovery rates can rise by 5–10 percentage points, reducing resource waste. Labor substitution: one piece of equipment can replace 20–50 manual sorting workers, yielding annual labor cost savings in the millions.
