The Relationship between Mineral Type and Density (g/ml) Purpose/Introduction: The purpose of this lab was to understand the relationship between minerals and density, the ratio of mass to volume, particularly, how density can be used to identify mineral type. In the lab, two samples of the mineral, feldspar, were measured for mass and volume in order to calculate their density. Many of the mineral tests yielded qualitative data, such as color, streak, luster, and crystal shape, which can be subjective. Other tests produced quantitative data, whose outcome of density is measured the same by anyone. Mineral density is determined by the specific chemical compound, because the mass and volume are dependent on the weight of the atoms. In this…

Australia is one of the richest countries in the world. They are rich with amazing people who are very talented yet stays humble. They are rich with a lot of trees that help the environment. They are also rich with minerals that are very helpful for their economy. Australia is very rich with different kinds of minerals and petroleum such as the coal, diamond, gold, iron and a whole lot more. These mines are accessible to people with the use of heavy equipments and with the help of mining…

Particle size plays an important role in evaluating the quality and performance of a mineral processing plant (Horiba 2014, 1). It also influences many of the properties of a particulate such as its reaction rate with some reagents. Particle size analysis is significant in determining the quality of ore grind and in establishing the degree of liberation of the valuable materials from the gangue (Haldar 2013, 227). This is done by mineral processing plants to ensure that the desired particle size…

Earth is composed of many different components such as minerals, and rocks. These components have several different properties and characteristics which are unique to each. In this paper, I will discuss some of the different properties, characteristics, and uses of three different factors, those being gypsum, coal, and nickel. Gypsum Gypsum is derived from the Greek word gypsos which means plaster (Gypsum Meanings, Powers, and History). Gypsum is composed of oxygen, calcium, sulfur, and water…

easily distinguished from gold by running some simple tests and doing some simple observations. Pyrite can form in many areas and shapes, the larger crystals can be perfectly formed into intriguing cubes, penetrating twins, and many other fascinating forms, while the smaller crystals can give of a shimmering or glistening effect in light. Especially adored by collectors, the perfect cubes of pyrite that are embedded in a matrix are most often found in the famous spanish mines.…

Park Field Trip was a really great experience where you get to see many different types of rocks and many diverse examples of minerals. This trip happened on Saturday November 1, 2014. Several geology classes went to the field trip for the expedition, with the purpose of learning the different types of each rock and its minerals and also to identify the stones from oldest to youngest. The group leaders of this trip were several professors of geology. Professor Croxen, Garrett, Dr. B, did…

Chalcopyrite is a copper iron sulfide mineral. Its coloring is metallic brassy to a brown-orange, and on the Mohs scale, it has a hardness of 3.5 to 4. The chemical formula of chalcopyrite is CuFeS2. It is the most commonly occurring copper containing mineral in New Zealand, but it is only created near volcanic areas. On the metaphysical level, chalcopyrite is used for meditation, specifically for opening the third eye chakra (crown chakra), and physical healing. The stone clears any energy…

Mintek develops and transfers new technology to industry for processing, extraction, refining and utilizing minerals and mineral products. This company offers research and development expertise, service test work, and technologies for the Gold, Platinum group…

Gissella Fajardo Treasure of the Earth: Gems Nova The title of the documentary that we watched today was “Treasure of the Earth: Gems Nova”. The intended audience is anyone that is interested on learning about gems like rubies, diamonds and sapphires.The purpose of the documentary is to inform the audience about gemstones. I didn’t know specific information about gemstones. During the documentary I learned that near the Earth's surface many gemstones are formed when…

Onyx: The Practical and Metaphysical Story Onyx is a specific variety of the mineral known as chalcedony. It is a banded mineral, which means that the layering of the rock that formed it has caused “bands” of different colors to appear. Many people mistake onyx for a type of agate, which is another type of chalcedony, but where agate has curved bands onyx has parallel bands instead. Onyx is found in nearly every color, though bands of black and white are the most common. When onyx is banded…
