Mining and Mineral Processing Industry Solutions
0101
Heavy-duty tungsten carbide components engineered for drilling, crushing, conveying, slurry handling, and centrifugal separation applications, designed to minimize downtime and reduce wear-related costs.
The mining and mineral processing industry requires equipment that can withstand extreme abrasion, high cyclic loads, corrosive slurries, and continuous operation. Under these conditions, conventional steel and cast iron components wear out quickly. Tungsten carbide (WC) wear parts provide the necessary hardness, wear resistance, and structural stability to ensure reliable operation in mines and processing plants.
Langsun Carbide provides tungsten carbide solutions engineered to extend equipment life, reduce maintenance frequency, and enhance operating reliability, with OEM components customized for different ore types and slurry conditions to effectively extend replacement intervals.
We support the entire process: material selection → prototyping → performance testing → production.

Key Challenges in Mining and Mineral Processing
Typical operating conditions in open-pit and underground mines, concentrators, and tailings facilities include:
● Extreme abrasion from ore, sand, rock, and mineral slurries
● High impact forces in grinding and crushing applications
● Corrosive processing environments (acid leaching, chemical slurries)
● Requirements for continuous, round-the-clock operation, making predictable component life essential
● High cost of downtime during maintenance and component replacement
Because any shutdown can halt the entire production line, predictable service life and long wear cycles of critical components are essential for maintaining throughput and controlling costs.
Key Failure Modes and Mitigation Strategies
|
Failure Mode |
Cause |
Components |
Mitigation Measures |
|
Abrasive wear |
Hard mineral particles (ore, sand, tailings) sliding or impacting on metal surfaces |
- Chute and hopper liners - Wear plates at transfer points - Centrifuge tiles and wear rings - Hydrocyclone liners and nozzle areas |
- Use high-hardness tungsten carbide–cobalt grades (e.g., YG8 / YG11 / YG15) - Reinforce the most severe wear zones with solid tungsten carbide components, tiles, or thick overlay layers |
|
Impact fracture |
High-energy impacts in crushers, drilling tools, and breaker hammer systems |
- Drill bits and drill collars - Crusher teeth and hammer crusher blades - Hammer heads and hammer tips |
- Use coarser-grain grades with higher binder content - Optimize geometry and edge radii to reduce stress concentrations and the risk of chipping |
|
Corrosion during leaching |
Attack from acidic leach solutions, chemically active slurries, or tailings liquor |
- Centrifuge wear parts exposed to leach solutions - Slurry nozzles and hydrocyclone components handling corrosive slurries |
- Use nickel-bonded tungsten carbide grades (e.g., YN6 / YN8 / YN10 / YN12) with superior corrosion resistance - Where necessary, combine with appropriate coatings or stainless/duplex steel backing structures |
Tungsten carbide offers exceptional wear resistance, hardness, and structural stability, making it the material of choice for high-wear environments in mining operations.

Material Grade Selection Guide
The following professional guidelines are based on proven tungsten carbide engineering principles. Selecting the proper grade is critical to achieving maximum service life and the highest level of reliability.
|
Application Environment |
Recommended Grade |
Binder Content |
Key Properties |
|
Severe abrasion (ore, sand, slurry) |
WC-Co grades: YG8 / YG11 / YG15 |
8–15% Co |
Very high hardness, excellent wear resistance, moderate toughness |
|
High-impact drilling and crushing |
WC-Co grades: YG20 / YG25 |
20–25% Co |
Increased toughness to prevent cracking under severe impact |
|
Corrosive chemical slurries |
Nickel-bonded carbide grades: YN6 / YN10 / YN12 |
6–12% Ni |
Excellent corrosion resistance with balanced wear performance |
|
Centrifuge wear parts |
Fine-grain carbide grades |
6–12% Co |
High erosion resistance in high-velocity slurry flow |
General guidelines:
● In sliding wear zones where abrasion is the primary wear mechanism and impact is moderate, use harder grades with lower binder content.
● Where impact, shock loading, or edge chipping is a concern, select tougher grades with higher binder content.
● In corrosive media where cobalt-based carbides are significantly affected, use nickel-bonded grades.
● For centrifuges and high-speed wear components, prioritize fine-grain carbides to maximize erosion resistance and surface integrity.
