Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore 0.2 . Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant

Copper minerals and ore are found throughout the Earths crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to makemercially viable to extract the rock. Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0.5 by mass. Ideally, the figure should
It follows the steps involved from exploration of the raw product, through the mining process involved, to environmental rehabilitation. Four main mining processes are shown: underground mining, strip mining, open pit mining and solution mining.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
The commonest ore used in the extraction of copper is Chalcopyrite CuFeS 2 also known as Copper Pyrites and other such sulfides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

The rock with less copper was called milling ore, or concentrating ore, and required crushing and separation of ore minerals from the waste rock to produce copper concentrate, which was sent to the smelter. Because metallic minerals have higher specific gravities than most gangue waste minerals, concentrating the milling ore was done in various gravity classifiers. The early Michigan copper

The main ore of copper is chalcopyrite CuFeS 2, which is often associated with other base or precious metal ores, notably those containing gold, galena PbS and sphalerite ZnS. In Victoria, copper bearing ores have been discovered in a variety of geological environments. These include deposits of exhalative volcanogenic origin, sulphide
This is an ore from a zone of Copper Porphyry which was located in southeastern New Brunswick. The overall grade of the ore was assayed at .35 copper and 600ppb AU or gold. This deposit is actually a project which myself and another prospector have been looking at over the last year. We found an outcrop while panning for gold in some of the streams along the Caledonia Highlands and stumbled

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. Chalcocite, bornite, idaite, covellite, and

To clean unevenly patinated copper: Sponge bathe copper with a mixture of six parts concentrated phosphoric acid to one part concentrated nitric acid diluted by no less than 50 percent distilled water to a pH between 1 and 1.5. A thickening agent can be added to the acid as a buffer and to contain the acid and make its removal and disposal easier.
Many copper ores also contain significant quantities of gold, silver, nickel and other valuable metals. Most of the copper ores mined in the United States contain only about 1.2 1.6 copper by weight. The average grade of copper ores in the 21st century is below 0.6 Cu, with a proportion of ore minerals being less than 2 of the total volume of the ore rock. Origin Of The Name. Around 3000
