Why representative sampling is essential in mineral processing, mining and extractive metallurgy
In mining, the starting point of the measurement and analysis chain is sampling.
Far from being a simple mass reduction exercise, correct sampling is about ensuring that the composition of the lot is preserved at every stage. It is an essential prerequisite for any accurate characterization of a material.
From exploration drilling to metallurgical accounting, the accuracy of your grade measurements, balances, and process evaluations depends on the representativeness of the samples you collect. ECHANT sampling software helps you to get reliable data from the start!
Why sampling errors matters
A sample that is not representative introduces bias, no matter how good your lab assays are.
The consequences are costly:
❌ Wrong mineral deposit estimate
❌ Questioned metal accounting
❌ Poor process design and plant optimization
❌ Financial and technical risks from inaccurate data
Even with rigorous sampling procedures, sampling errors remain. These errors are inherent to the heterogeneity of ores, concentrates, and tailings. Among them, the Fundamental Sampling Error (FSE) is irreducible, but it can be quantified and minimized through proper design. That is where ECHANT sampling software comes in.
How to minimize sampling errors with ECHANT
ECHANT helps you to calculate the degree of confidence in your measurements, a critical factor in quality management. It calculates the Fundamental Sampling Error (FSE) for a proposed sampling plan and guides you in designing step-by-step sampling plans that minimize a predetermine precision objective.
The software covers the full scope of mining-related materials. ECHANT can be used for:
- Ores for particle size, grade, and moisture
- Industrial residues such as slags and tailings for pollutant quantification
- WEEE as a secondary source of metals for composition and recovery analysis
- Soils for particle size, moisture, and contamination levels
Built on Pierre Gy’s Theory of Sampling, ECHANT gives you the clarity and control to minimize error, ensuring QA/QC compliance, and make data-driven mining decisions. It transforms complex math into practical sampling decisions.

Frequently Asked Questions (FAQs): using ECHANT and the free trial
What is ECHANT sampling software?
ECHANT is a sampling software based on Pierre Gy’s Theory of Sampling. It helps mining professionals to design representative sampling plans, calculate the Fundamental Sampling Error (FSE), and determine the minimum sample mass required for accurate results. ECHANT is both a sampling errors and sampling mass calculator and a sampling plan designer. It turns sampling error into measurable, manageable data you can trust.
What types of materials can ECHANT be used for?
With ECHANT, you can design sampling plans and calculate errors for:
- Ores – determine particle size distribution, mineral or chemical content (gold, silver, copper, carbonatesetc.), and moisture levels for grade control, feed blending control and process optimization.
- Industrial residues (slags, tailings, process waste) – quantify pollutant grades such as arsenic, sulphides or mercury to support safe disposal or potential reprocessing.
- Waste Electrical and Electronic Equipment (WEEE), end of life batteries – analyze composition and metal phases in secondary resources to improve recovery of precious and critical metals.
- Soils – characterize particle size and moisture content for mining site management.
- Polluted soils – assess contamination levels (hydrocarbons, metals, and other pollutants) for environmental monitoring and rehabilitation.
Originally developed for ores and concentrates, it can be used to solve sampling problems of solids and mixtures of solids (particles, aggregates, two-phase) in various industries, including municipal solid waste, food and biomass, pharmaceutical, cosmetics, amongst others.
