About This Chapter
Mineral Types, Properties and Uses - Chapter Summary and Learning Objectives
This chapter can introduce you to criteria for identifying minerals, as well as the properties used to differentiate one type from another. You can also explore mining techniques alongside the roles developed and developing nations play in the consumption of these resources. This chapter is designed to teach you:
- Physical properties of minerals
- Minerals' chemical characteristics
- Environmental impacts of extracting minerals
- Economics of mineral consumption
|What Are Minerals? - Types, Properties & Examples||Lists the four criteria used to identify minerals, as well as their observable physical properties.|
|Mineral Consumption: How Developed and Developing Nations Consume Minerals Differently||Explains the distribution of minerals and the relationship between a nation's consumption of minerals and its wealth.|
|Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use||Discusses the impacts of surface, strip, subsurface, longwall and solution mining techniques, as well as smelting.|
|Mining and Refining: The Environmental Impacts of Mineral Use||Shows how mining and refining processes disrupt the landscape, cause erosion and release toxic chemicals into the air and water.|
|Optical Properties of Minerals: Luster, Light Transmission, Color & Streak||Defines and describes the optical properties of minerals, including luster, opacity, transparency, translucency and streak.|
|Crystal Shape of Minerals: Forms and Types||Explains how crystal shapes or habits form and describes the different types, including bladed, fibrous, tabular, prismatic, platy, blocky and botryoidal.|
|Mineral Strength: Tenacity, Hardness, Cleavage & Fracture||Describes the various ways to measure mineral strength, including tenacity, hardness and shape when broken.|
|Mineral Density & Specific Gravity: Definition and Properties||Defines and differentiates between mineral density and specific gravity before comparing these properties among different minerals.|
|Silicate Minerals: Chemical Classifications & Examples||Identifies the silicon-oxygen tetrahedron as the fundamental building block of silicates and describes the major silicates, including feldspars and quartz.|
|Non-silicate Minerals: Chemical Classifications & Examples||Describes and provides examples of the major non-silicate minerals, including carbonates, sulfates and halides.|
1. What Are Minerals? - Types, Properties & Examples
In this lesson, you will learn about minerals and their properties. You will also understand the importance and everyday use of different types of minerals found on Earth.
2. Mineral Consumption: How Developed and Developing Nations Consume Minerals Differently
In this lesson, you will learn about how minerals are used around the world. You will also gain an understanding of where minerals are found on earth and how developed and developing nations consume them differently.
3. Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use
In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.
4. Optical Properties of Minerals: Luster, Light Transmission, Color & Streak
Minerals are conveniently identified based on their physical properties. These properties include luster, ability to transmit light, color and streak. This lesson will describe each of these properties and examples of each.
5. Crystal Shape of Minerals: Forms and Types
Did you know that the term crystal can have different meanings in addition to something pretty to look at? A crystal can refer to a regular pattern of molecules within a mineral or the shapes at a macroscopic level. This is also known as the crystal habit.
6. Mineral Strength: Tenacity, Hardness, Cleavage & Fracture
What does it mean to say that one mineral is stronger than another? This lesson will explore different minerals to identify and describe mineral strength in terms of tenacity, hardness, cleavage and fracture.
7. Mineral Density & Specific Gravity: Definition and Properties
Mineral density and specific gravity are similar properties used by mineralologists to identify minerals. This lesson describes a common practice used to determine density and specific gravity.
8. Silicate Minerals: Chemical Classifications & Examples
Silicate minerals make up the bulk of the earth's crust. All silicates are made of the same building block, the silicon-oxygen tetrahedron. This lesson describes the major silicate minerals including feldspars and quartz.
9. Non-silicate Minerals: Chemical Classifications & Examples
While most minerals are silicates, many non-silicate minerals are found in the earth's crust and are important as well. This lesson will use examples and describe the three major groups of non-silicate minerals, including carbonates, halides and sulfates.
