Mineral Testing Laboratory

Mineral Testing

Minerals are naturally occuring chemical compounds with a definitive atomic structure. This definitive structure has a clear chemical makeup that defines the mineral type. Physical characteristics of minerals include measurements like streak, hardness, lustre and cleavage.

Some minerals are composed of one element, like gold, silver and copper, but most minerals form from a combination of natural materials. For example, limestone is composed of calcite and aragonite — two crystal forms of calcium carbonate.

These materials often organically occur in caves, lakes, oceans, volcanoes and other natural areas. Given the time and natural processes required to create these materials, there is always potential to discover new ones. Thousands of minerals have been discovered since the beginning of humanity, and we have found numerous applications for these crystalline materials today.

Construction operations use minerals as raw building materials and road aggregates. Industrial manufacturers create chemicals, plastic, paper and other materials with mineral processing. We also use minerals for energy, such as burning coal to generate electricity. These raw materials are foundational supplies for industries fueling our economy.

With the essential role minerals have in our world, synthetic minerals have become increasingly common as cost-effective alternatives. Humans have created completely new minerals that cannot be found in nature. Whether you source natural or synthetic minerals, you want confirmation that the chemical composition reflects the type advertised. McCreath Laboratories specializes in mineral testing for various types, such as:

  • Bauxite
  • Dolomite
  • Feldspar
  • Fluorspar
  • Ilmenite
  • Limestone
  • Magnetite
  • Olivine
  • Pyrite

Mineral Testing Services

Mineral testing is essential, given the presence of these materials across industries and the potential for low-grade synthetics. McCreath serves operations with various mineral testing services:

  • Laboratory services: McCreath mineral testing laboratories apply innovative testing methods, such as emission, ion column and combustion analysis, to define a mineral’s physical and chemical characteristics. Our chemists and technicians use modern instrumental and analytical techniques for precise assessments. We perform all mineral tests under our roof for quality control and align with your tight deadlines without sacrificing precision. 
  • Sampling: For sample assessments to be accurate, they must be systematically collected to represent the mineral stockpile. Our experienced professionals use industry-accepted practices to collect samples representing bulk supplies. We use mobile vehicles for on-site sampling to maintain precision. Our involvement in this stage is crucial to mineral testing quality control. Improper sampling may skew results and fail to encompass the quality of a bulk supply.
  • Inspections: You may source minerals from anywhere in the world — inspection services verify the handling, quantity and condition of these raw materials. A McCreath field representative can survey your stockpile to determine its weight. Our representatives use standard measuring equipment to measure pile dimensions and determine bulk density. Our office staff will use these values to calculate volume and tonnage. Inspection services can also include supervision for loading, discharging, transporting and sampling from outside parties.
  • Consulting: Our experienced staff can provide solutions for efficiency, troubleshooting and problem-solving in material handling. We assess your current processes and apply our industry experience to optimize your approach. We have curated a team of highly trained professionals with the utmost technical confidence to guide material handling within your operation.
