Minerals, Ore and Mining Testing
Minerals have four classifications based on their economic use:
Energy Minerals are those which are mined to produce electricity and fuel. Energy minerals include coal, oil, and natural gas.
Metals are mined for an abundance of uses; commonly: Iron for steel production for vehicles and building materials, Copper for electrical, and aluminum for packaging and aircraft.
Construction minerals include sand and gravel, brick clay and crushed rock aggregates. They are used in the manufacture of concrete, asphalt, bricks, etc.
Industrial minerals are non–metallic minerals used applications including the manufacture of chemicals, glass, fertilizers, pharmaceuticals, plastics and paper.
Clark Testing has a long history of providing testing services to producers, distributors, and end users of various Minerals. Clark provides on-site sampling services at mine sites or barge and rail terminals.
We perform the preparations necessary for testing which may include machining of the materials, notably crushing. Clark’s Analytical Chemistry lab
and Particle Characterizing lab
offer both the chemical composition and physical property testing. Following ISO/IEC 17025 quality guidelines, we give the reassurance that mineral products meet our customer’s criteria for their application and industry specifications.
Testing services most commonly include:
- Crystalline Phase Identification
- Elemental composition
- Particle Sizing
- Surface Area
- Cement (Portland)
- Silica Sand
- EAF Slag
- Slag Conditioners
