Geochemistry is a fundamental part of mineral exploration and mining, providing data essential for decision-making. Behind every data point is a detailed laboratory process. To clarify this process and highlight the work done in geochemical laboratories, LKI Consulting si launching a new blog series.
This series will follow a sample’s path—from preparation to final analysis—and provide insights for geoscientists at every stage. Whether you’re a geochemist, a geologist, or simply curious about laboratory workflows, this series is for you.
Here’s what to expect:
- Sample Preparation: An overview of the initial steps, including cataloging, drying, and preparing samples for analysis. This stage is critical for producing reliable results.
- Crushing and Grinding: A look at the methods and tools used to reduce samples to fine particles for consistent and representative analysis.
- Digest Methods: A comparison of common methods such as aqua regia, 4-acid, weak leaches, and sequential leaches, along with their uses and limitations.
- Analytical Finishes: An explanation of techniques like Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and fire assay that convert digested samples into geochemical data.
- Quality Assurance and Quality Control (QA/QC): Guidance on setting up a QA/QC program to ensure data integrity and reliability.
We will cover common challenges, share tips for improving workflows, and provide practical advice to maximize the value of geochemical analyses.
By the end of this series, you will have a clear understanding of the processes that make geochemical laboratories essential to mineral exploration and mining. Join us as we explore the science behind the data.
Stay tuned for the first installment on sample preparation—a crucial step that sets the stage for everything that follows.
