Copper Ore Processing Methods

Copper Ore Processing Methods. Previous Next. View Larger Image ; The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is

How to Locate Copper Deposits Sciencing

Geologists employ many techniques to locate copper deposits, from testing the components of ore to studying land features to determine probable locations for a copper deposit. The process is not as easy as it once was, in part because environmental regulations prevent exploratory digs deep in

How to Test Ore or Rock for Gold Content

If the ground ore be found to contain metallics an amalgamation test should be made on the ore prior to cyanidation for which purpose a kilo of the ground ore may be made into a pulp with water and passed over a small amalgamated copper plate several times. The ore should also be tried by cyanidation under various conditions without previous

Copper Facts: stone and Physical Properties

Copper ore deposits are known in North America, South America, and Africa. Copper is obtained by smelting, leaching, and electrolysis of the copper sulfides, oxides, and carbonates. Copper is commercially available at a purity of 99.999+ %. Element Classification: Transition Metal. Isotopes: There are 28 known isotopes of copper ranging from Cu-53 to Cu-80. There are two stable isotopes: Cu-63

Copper Flotation Mineral Processing & Metallurgy

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel grinding and flotation circuits. For additional

Identifying Ores of Silver, Copper and Lead Nevada Outback

Characterization and evaluation of silver, copper and lead deposits. Identifying Ores of Silver, Copper and Lead. Silver: Silver is generally found in serpentine, trap,sandstone, limestone, shale, or porphyry rocks, the gangue being quartz, calc, fluorite, or barite. All silver ores are heavy, and many of them are sectile, i.e., may be cut with the knife. Western men test for silver by

Chemical tests for the metal content of various ores

Copper: Copper is a very easy mineral to test for. First crush the ore and dissolve it in nitric acid by heating. Then dilute with some water, and add ammonia. The solution should turn dark blue. The carbonate ores of copper do not extend deep in the mine. Their places are taken by copper pyrites. Sulfide ores are usually difficult to treat, and when they are to be tested it is better to roast

How Do You Find Out If Something Is Copper? LEAFtv

Copper is notoriously soft, so it can be difficult to keep a piece perfectly smooth when working with the copper. If the copper piece is thin enough, you may even be able to bend it with your bare hands. You may also knock on the piece and listen to the sound that it makes. Real copper will have a deep and mellow sound, as opposed to brass, which can be high-pitched and tinny.

How to Determine if Copper Is Real Sciencing

Determine if an object contains copper with a magnetism test, a resistivity test, density measurement and hydrochloric acid application. Magnetism Test. Copper is only slightly magnetic. Therefore, if you hold a magnet close to the copper object you wish to test, you shouldn't see any effects. Powerful magnets, however, may have a slight effect on your copper object. When you drop a strong

Copper extraction Wikipedia

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
