Minerals | Definition of Minerals at
Minerals definition, any of a class of substances occurring in nature, usually comprising inorganic substances, as quartz or feldspar, of definite chemical composition and usually of definite crystal structure, but sometimes also including rocks formed by these substances as well as certain natural products of organic origin, as asphalt or coal.

Geological Society Chemical Weathering
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic. These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.

Chemical Weathering an overview | ScienceDirect Topics
Chemical weathering of rocks is a spontaneous (, irreversible) thermodynamic process leading to a more stable state for natural materials under a given set of conditions (, temperature and pressure). It results from the reaction of aqueous, acidic, and oxidizing solutions with the minerals in rocks and soils.

The Mineral vs Chemical Sunscreen Debate | NUVO
Along with the perceived risks of chemical products, interest in mineral sunscreens is on the rise. "UVA rays are causing damage to the skin by generating free radicals, and the best way to stop free radicals from causing skin damage is to use antioxidants," says Kateline Turgeon, director of training for La RochePosay Canada.

Introduction to Mineral Processing Chevron Phillips Chemical
A collector is a chemical that attaches to the mineral surface and produces a hydrophobic (waterfearing) surface. While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used. This waterrepellent film facilitates the attachment of the mineral particle to the air bubble.

Soil Minerals University of Hawaii
Chemical weathering involves the change, or transformation, of primary minerals into secondary minerals. Secondary minerals serve as the basic building blocks of the small particles with the soil. As a result, new materials may be synthesized, residual material may accumulate from materials (such as oxides) which cannot be furthered weathered, or materials can be lost as the result of leaching.

Mineral Properties | Mineralogy4Kids
A mineral is a naturallyoccurring, inorganic solid which possesses a characteristic internal atomic structure and a definite chemical composition. If we take the definition of a mineral term by term, it becomes easier to understand: Minerals must occur naturally. This means manmade substances such as steel aren't minerals.
