Crystal Habit, and Cleavage. Pyrite. • Properties depend upon – Chemical composition. – Crystal structure. CONTENT OF CHAPTER 1. ? Goal: learn how to describe and classify minerals. ? 3 elements of classification: chemistry, structure and environment. ? Outline: ? Occurrences of minerals. ? Classification of minerals. ? Physical properties of minerals For example, a water molecule is composed of H2O - two hydrogen atoms and one oxygen atom. When water molecules are grouped together, they form a body of water. Trace amounts of foreign molecules not inherent to a mineral's makeup are known as impurities. Impurities can slightly alter physical properties such as Chapter 7 Physical properties of minerals. Study the direct result from chemical and structural characteristics of minerals. 1. Crystal habits and aggregates: appearance of single-aggregate in terms of feature aids that can be recognised. (A) Isolated or distinct crystal. - Acicular: slender, needlelike crystals. - Capillary and Welcome to lecture 2. From the previous lecture you have covered, it is now clear that a relationship exists between the crystal structure and physical properties of minerals. Lecture 2 has the aim to show you that close onnections do exist between the physical properties of a mineral, its crystal structure and its chemical MINERALS. The physical and chemical characteristics of minerals and rocks are considered in mineral processing to achieve the separation. Based on the fact that both the valuable and waste minerals exhibit different behavioural patterns, appropriate separation techniques are employed. Some of the important properties Color, luster, streak, hardness, cleavage, fracture, and crystal form are the most useful physical properties for identifying most minerals. Part A. Physical Properties Associated with Light Metallic minerals commonly develop a tarnished outer surface that masks the true luster, until scratched. Luster is the appearance of the mineral's fresh surface in reflected . especially the soluble minerals, the same way one does not ingest reagent chemicals from your. 19 Jul 2013 Teacher has tried to illustrate the following points in this Lecture : Chemical Properties Of Minerals, Igneous Textures, Composition, Major Elements, Incompatible, Trace, Weight, Incompatible, Magma, Minerals, Study n$
