The high-grade copper concentrate can be obtained by the coarse grinding, roughing, scavenging of copper ore, then grinding and concentrating of coarse concentrate. Classification of copper ore Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The specific process ...
An Investigation into Pre-concentration of Low-Grade ...
Pre-concentration stages are generally employed to process base and precious metals where the feed grades are inferior. The pre-concentration could remove major gangue minerals and enrich the desired metal content. Further, it improves the efficiency of subsequent concentration stages. In the present investigation, pre-concentration studies were carried out on the mixed copper ore from ...

Copper Ore Processing Methods
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 ...

Copper mining in the United States - Wikipedia
The rock with higher copper content was smelter ore, also called direct shipping ore, and required no treatment before going to the smelter. 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.

Chapter 6 Copper Production Technology
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 of cop-per production have remained unchanged for 65 years.

Ore deposits formed by oxidation and supergene enrichment
Ore Deposits Formed by Oxidation and Supergene Enrichment · When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. · The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. · An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to ...

Learning Goals: -What is an ore deposit?
which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.

ON-SITE PROCESSING VS. SALE OF COPPER CONCENTRATES
market, i.e.supply of concentrate vs smelting capacity. When copper prices are low, naturally supply of concentrate dries up fairly quickly, whereas smelters keep going, thus there is a rough relationship as one might expect between copper prices and treatment charges. Figure 3 presents the historical copper prices and TC/RCs from 1986 to present.
