Chapter 6 Copper Production Technology

Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods ...

Properties of Copper Ores - University of Arizona

Branicoda Mining Operations is considering opening up a new mining site. The geologists feel that there are copper-rich ore bodies present at this new site. There is an abundance of water and sulfuric acid that could be used to dissolve (leach) the copper compounds found in the ore if this is possible.

COPPER Copper production - Repository

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.

LUMWANA COPPER PROJECT ENVIRONMENTAL IMPACT ASSESSMENT

The Project has a planned life of mine of 18 years and will involve the mining of two distinct areas. Area 1 is the Malundwe deposit which will be mined from year 1 to 5. Area 2 is the Chimiwungo deposit and will be mined from year 6 to 18. On average 20 million tonnes of copper ore will be mined each year, producing an average of

The Role of Arsenic in the Mining Industry

Since valuable metals such as copper and gold can also be found in sulfide mineral deposits, mining exploration companies will often look for soil and water with a naturally high arsenic content as a means of locating an ore body. [9] It is, therefore, very important to establish baseline or existing arsenic concentrations in the

Copper Ore Processing Methods

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 concentrated. The milling of copper ores as practiced in the larger ...

5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic production. Copper was also recovered at mines in three other States.
