Lab Design for Accurate Sample Preparation
When it comes to ensuring the accuracy of assay data , laboratory layout for sample preparation plays a critical role. A well-designed lab prevents cross-contamination, streamlines workflows, and ensures that each sample is processed under optimal conditions. Without a structured layout, contamination risks increase, compromising grade control, plant performance, and mine sales decisions.
Preventing Cross-Contamination Through Smart Design
The primary objective of laboratory layout design is to prevent cross-contamination between different sample types. This is achieved by maintaining clear separation between sample flows.
Key Separation Strategies:
- Geology and grade control samples must be kept separate from plant samples, as plant samples often contain high-grade concentrates.
- Even within plant samples, additional segregation is necessary—concentrate samples should not be processed alongside feed and tails samples.
- Dedicated preparation areas for different sample types reduce the risk of contamination and improve the reliability of assay results.
The Ideal Laboratory Layout for Sample Preparation
The best approach is to designate separate spaces for different sample types. The diagram below illustrates an optimal laboratory layout where geology sample preparation is clearly separated from plant sample preparation, minimising the risk of cross-contamination.
Practical Laboratory Layout Examples
Laboratories worldwide have implemented different strategies to ensure efficient and contamination-free sample preparation. Below are examples of pulveriser and crusher setups that support accuracy and workflow efficiency.
Example 1: Twin Pulveriser Setup
This layout allows for a compact but efficient use of space, enabling streamlined sample processing while preventing mix-ups.
Example 2: Single-Operator Workbench
This configuration is ideal for smaller-scale operations where one technician manages multiple pulverisers efficiently.
Pulverisers and Crushers Combined
This design enhances efficiency by keeping crushing and pulverising stations in close proximity while maintaining clear separation.
Example 4: Dedicated Pulveriser Workbenches
In high-throughput commercial labs, separate pulveriser stations improve efficiency and reduce contamination risks by ensuring dedicated workspaces for sample processing.
The Bottom Line: Design for Accuracy and Efficiency
An optimised laboratory layout for sample preparation is essential for producing reliable assay data. By strategically separating sample types, ensuring efficient equipment placement, and minimising contamination risks, laboratories can uphold the highest standards of accuracy.
Whether designing a new facility or improving an existing one, focusing on practical layout solutions will enhance workflow efficiency, protect sample integrity, and provide confidence in assay results.
