Properties of Copper Ores

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.

Bornite

Bornite has a brown to copper-red color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname peacock copper or peacock ore. Mineralogy. Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.

Introduction to Spectroscopy: Analysis of Copper Ore

Earth''s surface. Prospecting for copper then was relatively simple. Recently, increased demand for copper resulted in numerous mines, and the search for copper ore is now very competitive. When a copper deposit is discovered, drilling is undertaken to determine the size and grade (concentration) of copper at the potential mining site.

Innovations: Introduction to Copper: Mining & Extraction

Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Copper: The mineral native Copper information and pictures

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.

Percentage Composition by Mass

Some mineral ores have a high percentage of a particular metal compound in them. However, the percentage of the actual metal itself might be the deciding factor as to whether the ore is worth mining. Copper is found in the mineral ores ''cuprite'' Cu 2 O, ''tenorite'' CuO and ''malachite'' Cu 2 (OH) 2 CO 3. Given the atomic masses: Cu = 64; O = 16.
