Ore Minerals An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often ...
Galena, a lead sulfide, has a much higher specific gravity than bauxite, an aluminum hydroxide. This difference is because of their composition. Lead is much heavier than aluminum. Diamond and graphite both consist of pure carbon. Diamond is the hardest natural mineral, and graphite is one of...

One of the largest deposits of fluorspar in North America is located in the Burin Peninsula, Newfoundland, Canada. The first official recognition of fluorspar in the area was recorded by geologist J.B. Jukes in 1843. He noted an occurrence of “galena” or lead ore and fluoride of lime on...
Chapter 6/ Lesson 3 96K Mineral strength is calculated by measuring tenacity, hardness, cleavage, and fracture. Examine the methods of each of these concepts through examples, and learn about the usage of the Mohs scale to determine the hardness of a mineral, and find examples of brittle, ma...
FAQs on What are Common Ore Examples? 1. How are ores extracted? When an ore is extracted, it contains several materials and is not directly useful. So, first it needs to go through a scientific process. The valuable minerals are segregated from the other non-useful materials. In flotation...
If the lead can be extracted with 92.5% efficiency, what mass of ore is required to make a lead sphere with a 4.50 cm radius? Ore: An ore is defined as a type of rock. This type of rock contains different elements. Some specific ores are...
