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.

How did iron extract from the ground?
Smelting: Mined out of the ground, raw ore is a mixture of materials called ore proper and loose earth called gangue (waste). The ore proper is separated by crushing the raw ore are simply washing away the lighter soil. Breaking down the ore from its impurities is more difficult.
Do you have to pass the sixth grade science TAKS to go to 7th grade?
No, not at the 6th grade level. The TAKS (Texas Assessment of Knowledge and Skills) is designed to measure the extent to which a student has learned and is able to apply the defined knowledge and skills at each tested grade level. You will need to either pass the TAKS or the STAAR tests in order to graduate from high school in Texas.

How much does iron ore cost?

What is the best quality of iron ore?
The best quality of iron ore is typically high-grade iron ore, which contains a high percentage of iron content and few impurities. High-grade iron ore is more valuable and in demand in the steelmaking industry because it requires less processing to extract the iron.
What does low-grade ore mean?
Low-grade ore refers to mineral deposits containing a lower amount of valuable materials compared to high-grade ore. This means that more material needs to be processed to extract the desired minerals, making it less economically viable to mine.
When was the carajas project started?
It is there because in 1967, large deposits of high grade iron-ore were found.
What is the difference between a copper rich ore and a low grade ore?

What is Ore grade?
Ore grade refers to the concentration of valuable minerals or metals in an ore. It is typically expressed as a percentage or in grams per ton. A higher ore grade indicates a higher concentration of valuable materials, which can impact the economics of mining and processing operations.
What happened at Ungava bay?

What is free milling ore?
Free milling ore refers to gold or silver ore that can be easily extracted and processed using standard mining methods without the need for additional processing or chemicals to separate the precious metals from the host rock. This type of ore is usually high in grade and easier to extract, resulting in lower production costs for miners.
What is the problem with using low grade ore as a copper source?
It is very hard and very expensive to remove the copper from that ore.
