What is the difference between Copper- rich ores and Low - grade ores?

∙ 9y ago
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper

An important copper ore mineral?
what are the ores of copper
What is the problem using low grade ore as a copper source?
The metal (copper) extracted may be generally brittle and break easily.
What is the difference between ore and ores?
In English ores is the plural of ore. Ore is a mined substance which may be used directly or from which other minerals and elements can extracted.
What are four minerals that are commonly taken from ores?
Copper, diamond, magnetite, gold.
Is extracting metals from ores cost effective?
Minerals are solid elements or compounds found naturally in the Earth's crust. Those minerals that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2 The resulting copper, however, is pure enough to be used for many industrial applications, but it has to be further refined for electrical uses. That copper is cast into thick sheets known as anodes and are placed in large electrolytic cells filled with a copper sulfate solution. A DC electric current is passed through the cells causing the copper anodes to dissolve and deposits pure copper on the opposite pole called the cathode. The final product is between 99.94 and 99.96% Cu.

What is the cost of extracting copper from low grade ores?
1000 dollars
What is the problem with using low-grade ores as a copper source?

What are ores of copper?
the ores of copper are chalcopyrite .malachite .azurite. and native copper.
What are the problems associated with using low grade ores?
It's poor quality and not all the copper can be extraxted from it
What is the ores of copper?
Ores of copper(Cu) are: -Chalcopyrite -Malachite -Azurite Native copper can also be found.
What is a high grade ore?
It's an ore that doesn't contain a very high proportion of valuable minerals. The term could also be applied to richer ores containing large amounts of undesirable impurities, arsenic for example. Low-grade ores are less valuable than higher-grade ones. Also, recovery rates for low grade ores tend to be lower than for high grade ores - that is, a lower percentage of the total amount of metal in the ore is extracted successfully. The definition of low-grade depends on the resource in question. For copper, low grade ores have less than 1% copper. For gold, an ore having 1% gold by mass would be considered (very) high-grade, as gold is more valuable than copper.
