9 Essential steps to guarantee quality in mining lab analysis

Laboratories that support the mining sector are central to mineral extraction, refining and processing, providing data-driven insights that boost productivity and support environmental responsibility. In this complex field, Labotec delivers advanced, quality laboratory equipment designed to meet the industry’s evolving demands, combined with technical after sales expertise and support, ensuring the accuracy, efficiency and durability required in mining labs.

1.        Size reduction

A primary function in mining laboratories is the size reduction of ores to reveal valuable mineral components. Labotec supplies equipment for milling and sizing that includes jaw crushers, disk mills, and pulverisette mills. These machines are vital for breaking down samples to prepare them for precise analysis. Complementing this are vibratory sieve shakers and rotating sample dividers for homogenization, ensuring representative samples across varying particle sizes.

2.        Sample preparation

 Sample preparation is critical for consistent and reproducible test results. Labotec offers industrial drying ovens, laboratory furnaces, and water purification systems that cater to specific requirements, such as removing moisture or achieving high purity. With offerings like glassware washers and water purification systems, Labotec supports cleanliness and precision, enhancing preparation processes across mineral, metallurgical and environmental labs.

3.        Measurement/ Electrochemistry

Environmental data and chemical composition analysis are crucial for mining and processing. Labotec’s electrochemistry meters, moisture analysers, and spectrophotometers enable accurate measurements for quality control, detecting moisture content, pH levels amongst other factors. These tools are essential in assessing ore characteristics, water quality, and even air contaminants, contributing to a safer and more compliant mining environment.

4.        Quality control and testing

Labotec provides nitrogen determination devices, stability testing equipment, as well as tools for water and effluent testing. This equipment ensures that mining companies meet environmental and safety standards, with instruments that test for contaminants and assess product stability under different conditions. Specialised flotation testing equipment also supports optimal recovery rates, refining the separation of valuable minerals from ore.

5.        High-pressure/ Temperature reactors

Labotec’s high-pressure reactors and calorimeters address the high-demand reactions in mining. These reactors allow for controlled high-pressure and high-temperature conditions, critical for testing reactions in mineral extraction. Pressure vessels and custom reactors support the unique needs of advanced metallurgical processes, while kinetic and reaction studies provide insights into reaction speeds and energy requirements, helping to optimise resource use.

6.        Liquid, chemical and gas transfer

Reliable fluid and gas transfer systems are vital in mining labs where precise dosing, chemical mixing and sample handling are required. Labotec’s KNF diaphragm pumps, peristaltic pumps, and slurry handling pumps ensure accurate liquid transfer, essential in chemical dosing and managing abrasive slurries. For air and gas monitoring, gas sampling pumps assist in environmental safety and regulatory compliance, enabling precise analysis in instruments like gas chromatographs.

7.        Weighing

Accuracy in measurement is key in mining labs. Labotec’s scales and balances allow for exact measurements, a crucial element in sample preparation and result reproducibility. Reliable weighing equipment is fundamental for handling and evaluating mineral samples, providing consistency across testing protocols.

8.        Sample and image analysis

Detailed sample analysis provides insights into mineral composition and structure. Labotec’s polarising and stereo microscopes enable labs to examine and document sample characteristics. Additionally, laser particle size analyzers offer precise particle measurement, helping labs optimise processing steps based on particle properties, essential in mineral extraction.

9.        Fume handling

Laboratories handling chemicals and toxic samples need effective fume extraction systems. Labotec’s Captair Smart ductless fume hoods protect users from hazardous fumes and ensure a safe working environment. These hoods filter airborne contaminants, which is crucial when handling volatile samples, and meet the safety needs of high-stakes lab environments.
