Jun , geology students are trained to identify the commonest rock and oreforming minerals its a vital skill for professional geologist sulphides, silicates, oxides, phosphates we slog through dozens of them in our petrology labs, learning to identify the important ones using properties like colour, hardness, lustre the way it shines or doesnt, cleavage how they split, density and such
The first steps in the production of a metal object are to extract the ore from the mine, process the ore for smelting, and then eventually smelt the ore into metal of minerals was based on

Mineralogy wikipedia mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical including optical properties of minerals and mineralized studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization
Optical mineralogy is the study of minerals and rocks by measuring their optical properties most commonly, rock and mineral samples are prepared as thin sections or grain mounts for study in the laboratory with a petrographic microscopeOptical mineralogy is used to identify the mineralogical composition of geological materials in order to help reveal their origin and evolution
Optical properties of minerals such properties of a mineral which are related to the behaviour of light while being transmitted through or reflected from it are grouped under optical properties they are of great significance in the determinative mineralogy and highly useful in identifying individual minerals occurring in very small
The optical property of a mineral depends on how it interacts with light several important optical properties are applicable to minerals and gemstones from a scientific standpoint these properties are extremely useful for identifying a mineral the most important of these properties are listed below
Many different mineral commodities are important to modern society however, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties eG, asbestos, micas, potash, and gems of all sortsThat is what we will focus on in most of the rest of this chapter
Optical properties of minerals such properties of a mineral which are related to the behaviour of light while being transmitted through or reflected from it are grouped under optical properties they are of great significance in the determinative mineralogy and highly useful in identifying individual minerals occurring in very small
Series of minerals that can carry gold as a physical constituent such as pyrite and arsenopyrite the mineralogy determines the recovery process of gold two types of gold ores can be distinguished non refractory ores and refractory ores non refractory gold ores permit a straightforward recovery by a relatively simple conventional technology
Sio and al o are two important minerals that can affect the mechanical and metallurgical properties of sinter this investigation systematically studied the influences of these minerals and revealed their functional mechanisms on sinter quality results showed that with an increasing al o content in sinter, the sintering indexes presented an improvement before the content exceeded
Advertisements after reading this article you will learn about the physical properties of minerals physical properties of minerals depending on light a form minerals assume different shapes, which depend upon the internal structure of the minerals different terms have been used to describe the forms of different minerals advertisements the important terms that are commonly
