What Size Wash Plant Do You Need?

The Most Important Mining Decision

Choosing the wrong size wash plant is the #1 mistake we see in gold mining. Too small, and you can't process enough material to be profitable. Too big, and you're overpaying for capacity you'll never use. After helping hundreds of miners choose the right equipment, here's your complete guide to wash plant sizing.

Our Complete Model Lineup

We offer five wash plant sizes to match any operation scale:

Model	Capacity	Best For	Shipping	Power
M30	30 cy/hr	Small operations, testing	1 x 20' container	50 HP
M50	50 cy/hr	Most popular, great ROI	1 x 20' container	75 HP
M100	100 cy/hr	Mid-size operations	1 x 40' container	100 HP
M200	200 cy/hr	Large-scale mining	4 x 40' containers	150 HP
M300	300 cy/hr	Maximum capacity	6 x 40' containers	220 HP

M30: Small Operations and Testing

The M30 wash plant is perfect for:

• Deposit testing: Prove your ground before investing in larger equipment
• Small-scale operations: Part-time mining or hobby operations
• Remote locations: Easy transport to difficult access sites
• Limited budgets: Get started with minimal investment
• Educational purposes: Learn wash plant operation before scaling up

Realistic daily throughput: 240-300 cubic yards (8-10 hour operation)

M50: The Most Popular Choice

The M50 wash plant is our bestseller for good reasons:

• Optimal economics: Best cost per cubic yard processed
• Single container shipping: Lowest shipping costs worldwide
• Manageable power: 75 HP works with most generators
• Proven capacity: 50 cy/hr handles most small-to-medium deposits
• Quick ROI: Typical payback in 6-12 months with good ground

Realistic daily throughput: 400-500 cubic yards (8-10 hour operation)

M100: The Sweet Spot for Growing Operations

The M100 wash plant offers excellent value scaling:

• Double the M50 capacity: 100 cy/hr for larger deposits
• Still single container: Ships in one 40' container
• Moderate power: 100 HP is generator-friendly
• Room to grow: Handles expansion without equipment change
• Professional operation: Supports full-time mining operations

Realistic daily throughput: 800-1,000 cubic yards (8-10 hour operation)

M200: Large-Scale Mining

The M200 wash plant is for serious mining operations:

• High capacity: 200 cy/hr for large deposits
• Proven design: Most popular large-scale model
• 24/7 operation: Built for continuous industrial use
• Multiple crew shifts: Supports around-the-clock operation
• Established operations: For proven, large-scale deposits

Realistic daily throughput: 1,600-2,000 cubic yards (8-10 hour operation)

M300: Maximum Capacity

The M300 wash plant is our highest-capacity unit:

• Maximum throughput: 300 cy/hr for huge deposits
• Industrial scale: Designed for major mining operations
• Continuous operation: Built for 24/7/365 operation
• Large infrastructure: Requires substantial site preparation
• Massive deposits only: Only justified for very large operations

Realistic daily throughput: 2,400-3,000 cubic yards (8-10 hour operation)

Key Decision Factors

1. Deposit Size and Grade

The size and richness of your deposit should drive your equipment choice:

• Small deposits (under 50,000 cy): M30 or M50
• Medium deposits (50,000-200,000 cy): M50 or M100
• Large deposits (200,000-500,000 cy): M100 or M200
• Massive deposits (500,000+ cy): M200 or M300

2. Material Type and Conditions

Different soil types affect throughput significantly:

• Sandy/gravelly material: Achieves rated capacity
• Clay-heavy material: Reduce capacity by 20-30%
• Rocky material: Pre-screening may be required
• Sticky clay: May require clay breaking equipment

3. Site Access and Infrastructure

Your site conditions limit equipment choices:

• Remote sites: M30/M50 easier to transport
• Poor road access: Smaller containers preferred
• Limited power: Smaller units need less generator capacity
• Water availability: Larger units need more water flow

4. Budget Considerations

Consider total cost, not just equipment price:

• Equipment cost: Larger units cost more upfront
• Shipping costs: Multiple containers add significant cost
• Site preparation: Larger units need more infrastructure
• Operating costs: Fuel, maintenance, labor scale with size

5. Operating Strategy

How you plan to operate affects size choice:

• Part-time operation: Smaller units make sense
• Single shift: Size for 8-10 hours daily operation
• Multiple shifts: Larger units justify 16-24 hour operation
• Seasonal operation: Consider weather limitations

Regional Preferences

Different regions favor different models:

Africa: M50 most popular due to shipping costs and site access

South America: M100-M200 popular for larger alluvial deposits

North America: Full range used, M200+ common for commercial operations

Australia/PNG: M50-M100 popular for remote mining

Common Sizing Mistakes

Undersizing (Most Common):

• Choosing M50 when you have material for M100
• Underestimating deposit size
• Not planning for growth
• Focusing only on initial cost

Oversizing:

• Buying M200 when you only have material for M100
• Overestimating deposit size
• Not considering site limitations
• Ignoring operating costs

Our Sizing Recommendation Process

When you call us, we'll ask about:

1. Deposit information: Size, grade, material type
2. Site conditions: Access, power, water availability
3. Operating plan: Hours per day, seasonal operation
4. Budget parameters: Equipment, shipping, total investment
5. Timeline: When you need equipment operational
6. Experience level: First wash plant or expansion

Start Smaller and Scale Up

When in doubt, our advice is usually to start smaller:

• Prove your deposit: Confirm gold recovery and material characteristics
• Learn the operation: Master wash plant operation before scaling
• Generate cash flow: Start earning while planning expansion
• Trade up later: We offer trade-in credit toward larger units

Many of our most successful customers started with an M50, proved their operation, then upgraded to M100 or M200 within 1-2 years.
