The Importance of Test Work in Mineral Processing: Why It Matters More Than Ever

In the mining and mineral processing industry, decisions around plant design, equipment selection, and process optimisation carry significant financial and operational consequences. Yet despite this, many projects still move forward based on assumptions, historical data, or “what worked before.”

At IMS Engineering, we believe that effective test work is one of the most important steps in reducing risk, improving efficiency, and ensuring long-term operational success.

What Is Test Work?

Test work is the process of evaluating ore characteristics and process performance under controlled conditions before full-scale implementation. Depending on the project scope, this can include crushing trials, sensor sorting trials, material characterisation, wear testing, process simulations, and pilot-scale production runs. The objective is simple: understand the material before making major capital or operational decisions.

No two ore bodies are the same. Variations in hardness, moisture content, abrasiveness, feed grading, clay content, and liberation characteristics can dramatically influence how material behaves in a processing circuit. Test work allows these variables to be understood and managed before they become costly operational problems.

Why IMS Invests Heavily in Test Work

At IMS Engineering, test work is not a “nice to have” — it is a critical part of how we partner with our customers.

Our philosophy has always been to provide engineered solutions, not simply sell equipment. To do that effectively, we need to understand the customer’s process, challenges, and material characteristics in detail.

IMS has invested significantly in its full-scale test facilities and technical capabilities because we believe that customers deserve data-driven recommendations backed by real-world performance testing.

Through test work, we can:

Validate equipment suitability
Optimise plant performance
Reduce operational risk
Improve product quality and consistency
Predict wear characteristics and maintenance requirements
Evaluate alternative process flowsheets
Support debottlenecking and plant expansion projects
Demonstrate performance before capital investment
Most importantly, test work gives customers confidence.

The Customer Benefits of Test Work

Reduced Risk

One of the greatest advantages of test work is risk mitigation. Installing the wrong equipment or implementing an unproven process can result in poor throughput, excessive downtime, high wear rates, poor recovery, or product specification failures. Test work helps identify these risks early before they impact production.

Improved Equipment Selection

Different applications require different solutions. A crusher or process that performs exceptionally well in one operation may be entirely unsuitable in another.

Through practical testing, IMS can accurately determine the best technology, configuration, and operating parameters for a specific application, ensuring customers invest in solutions that are truly fit for purpose.

Increased Operational Efficiency

Well-executed test work often identifies opportunities to improve throughput, reduce recirculating loads, minimise energy consumption, and optimise downstream processes.

Small process improvements can deliver substantial long-term savings across the life of a plant.

Better Understanding of Material Behaviour

Material variability remains one of the biggest challenges in mineral processing. Test work provides valuable insight into how ore behaves under different operating conditions, helping operations prepare for variability and improve process stability.

Lower Total Cost of Ownership

The cheapest solution upfront is rarely the cheapest solution over the life of an operation.

By validating performance, predicting wear, and optimising process efficiency, test work helps reduce maintenance costs, improve equipment life, and maximise return on investment.

Full-Scale Testing: Bridging Theory and Reality

One of the unique advantages IMS Engineering offers is the ability to conduct full-scale testing under realistic operating conditions.

Laboratory testing provides valuable insight, but full-scale trials offer a far more accurate representation of how equipment and material will behave in an operational environment. This allows customers to move forward with greater certainty and confidence.

Our test facilities enable customers to:

See equipment perform in real-world conditions
Compare alternative technologies
Validate throughput and product sizing
Assess wear performance
Evaluate process efficiency
Train operational teams before commissioning
For many customers, the ability to physically witness the process and results becomes a critical part of the decision-making process.

More Than Equipment — A Technical Partnership

At IMS Engineering, we see test work as the foundation of a long-term technical partnership.

Our role is not simply to supply machinery. It is to help customers make informed decisions that improve productivity, reliability, and profitability over the long term.

By combining technical expertise, practical operational understanding, and world-class technology partners, IMS works alongside customers to develop solutions that are tailored to their unique operational requirements.

Conclusion

In an increasingly competitive mining environment, operational efficiency and process reliability are more important than ever. Test work provides the technical understanding needed to make smarter decisions, reduce risk, and maximise plant performance.

For IMS Engineering, test work is about far more than testing equipment — it is about delivering confidence, certainty, and measurable value to our customers.

Because when the right decisions are made upfront, the results are seen throughout the life of the operation.
