Telluride minerals such as calaverite, are also important silver ores in some mining districts. This sample of rich gold and silver ore comes from the Cripple Creek district in Colorado. The mossy metallic colored mineral on this specimen is calaverite, a mineral rich in both gold and silver.
How to Locate Copper Deposits | Sciencing
Remove samples of the rocks and take them back to the lab for testing. If the rocks have a high part per million count of copper, then you may have found a copper deposit. How much copper needs to be in the ore before you mine the deposit depends on the method you wish to use to extract the copper.
Sampling of run-of-mine mill feed— A practical approach
sample must be completely representative of the whole as regards all aspects save bulk1. A fundamental aspect of nearly all mineral deposits is the inherent variability of the mineral assemblage and composition. The major problem with sampling broken ores lies in ensuring that the sample being analysed is representative of the bulk (or its parent
Extracting copper. Extracting copper. - SchoolScience.co.uk
Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

Did you know?... At least 160 copper-bearing minerals have been identified in nature; some of the more familiar minerals are chalcopyrite, malachite, azurite, and turquoise. Copper consumption changes from 1980 through 2008 for India, the United States, China, and the rest of the world. The qualities of copper that have made it the material
Copper & Kids - Where Does Copper Come From?
Ore is first mined, then put through a series of processes to refine and purify the copper. The USA is the second largest producer of copper in the world. The largest copper mine is found in Utah (Bingham Canyon). Other major mines are found in Arizona, Michigan, New Mexico and Montana.
How to Test Ore or Rock for Gold Content
It is advisable first of all to examine the ore for visible gold and silver, the presence of which might influence the choice of a method of treatment. If no gold or native silver can be seen in the rock, take a representative sample of about 300 grams and grind it up to pass a No. 30 sieve.
How copper is made - material, used, processing, steps ...
Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
SAMPLING, SAMPLE PREPARATION AND DATA ANALYSIS
Random sampling is often preferred because it avoids human bias in selecting samples and because it facilitates the application of statistics. In s ystematic sampling the samples are drawn systematically with location or time, e.g., every 10th box in a truck may be analyzed, or a sample may be chosen from a conveyor belt every 1 minute.

copper processing | Definition, History, & Facts ...
Ores. Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Ore - Wikipedia
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore ...

Heap leaching - Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

The sample is sieved on-site using a 80 mesh sieve, 178 micrometres, using a stack of sieves with progressively finer mesh sizes. This ensures that the finer clay and silt size particles are concentrated as this is the particle size range which contains the highest concentration of common indicator elements such as copper, lead, zinc and arsenic.
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 extraction and purification
Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
