Minerals - Properties of Minerals What Is a Mineral? A mineral is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition.

Minerals - Properties of Minerals Calculating Density To calculate the density of a mineral, divide the mass of the mineral sample by its volume. Density = Mass/Volume For example, if a sample of olivine has a mass of 237 g and a volume of 72 cm 3, then the density is 237 g/72 cm 3 = 3. 3 g/cm 3 Practice Problem A sample of calcite has a mass of 324 g and a volume of 120 cm 3. What is its density? 324 g ÷ 120 cm 3 = 2. 7 g/cm 3

Minerals - Properties of Minerals Mineral Density Use the line graph of the mass and volume of pyrite samples to answer the questions.

Minerals - Properties of Minerals Mineral Density Reading Graphs: What is the mass of Sample B? What is the volume of Sample B? 50 g; 10 cm 3

Minerals - Properties of Minerals Mineral Density Calculating: What is the density of Sample B? 5 g/cm 3

Minerals - Properties of Minerals Mineral Density Reading Graphs: What is the mass of Sample C? What is the volume of Sample C? 100 g; 20 cm 3

Minerals - Properties of Minerals Mineral Density Calculating: What is the density of Sample C? 5 g/cm 3

Minerals - Properties of Minerals Mineral Density Comparing and Contrasting: Compare the density of Sample B to that of Sample C. The density of samples B and C is the same.

Minerals - Properties of Minerals Mineral Density Predicting: A piece of pyrite has a volume of 40 cm 3. What is its mass? 8 g

Minerals - Properties of Minerals Mineral Density Drawing Conclusions: Does the density of a mineral depend on the size of the mineral sample? Explain. No; density does not depend on size. Larger samples have more mass, but the ratio between mass and volume is constant.

Minerals - Properties of Minerals Identifying Minerals The crystals of each mineral grow atom by atom to form that mineral’s particular crystal structure. Geologists classify these structures into six groups based on the number and angle of the crystal faces.

Minerals - How Minerals Form Where Minerals Form Minerals can form on the surface through evaporation of solutions containing dissolved minerals. Minerals can form beneath the surface when dissolved elements and compounds leave a hot water solution or when magma cools and hardens.

Minerals - How Minerals Form Asking Questions Before you read, preview the red headings. In a graphic organizer like the one below, ask a how or what question for each heading. As you read, write answers to your questions. Questions How do minerals form from magma? Answers They form when magma cools and crystals grow. How do minerals form from solutions? They form when solutions evaporate or cool.

Minerals - Using Mineral Resources Producing Metals From Minerals In the process of smelting, an ore is mixed with other substances and then melted to separate the useful metal from the other elements the ore contains.

Minerals - Using Mineral Resources Using Prior Knowledge Before you read, look at the section headings and visuals to see what this section is about. Then write what you know about mineral resources in a graphic organizer like the one below. As you read, write what you learn. What You Know 1. 2. The gems used in jewelry are minerals. Metals come from Earth. What You Learned 1. 2. Minerals are also the source of metals and other useful materials, like quartz and gypsum. Most metals come from ores, which are mined and smelted before the metals can be used.
