Can the classification of a mineral as an ore change if so how?

Some chemical compounds can have more than one crystal form. Calcite and Aragonite would be such an example.
In addition, there can be substitution of one element by another of similar charge and mass. In a specimen of heulandite I have, some of the original calcium has been replaced by barium, and eventually by strontium, to the extent of about 10%.
The mica group would be a good example of various forms of very similar minerals.
To some extent it depends upon how strictly one conforms to the definition of a mineral with 'a fixed chemical composition'.
Additionally, the effect of including trace contaminants is well illustrated in the various silicate crystal gems.

Are people made out of metal?
Metal in its natural state is a mineral occurring in the form of ore. It then needs to be mined, extracted from the ore and processed to make whatever. So a metal object is man made from a naturally occurring material. Unless of course it was made by a woman.
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.
What are some examples of binary classification?
I don;t know so some one who does take this out and put the real answer
How mineral water does differ from distilled water?
mineral water contains salts. Distilled water does not contain any salts, it's just water. And bottled water comes in a bottle. As a "food" item I expect it has to pass food safety standards, but otherwise it could be anything. Mineral water is water that has had minerals dissolved into it as a result of being stored underground. Spring water is mineral water for example. Depending on where the mineral water has come from effects the mineral content of the water. Distilled water on the other hand has been distilled. That mean it has been turned into steam, then the steam is allowed to cool turning it back into water in a clean container. What happens as a result is that only the water turns into steam leaving the mineral content behind giving you pure water with no mineral content.
What does the word physical change mean?
A physical change means that only the appearance of the substance has changed. So if your tear up a piece of paper, its still paper so a physical change has taken place. If you heat or freeze water its only a change of state so its still a physical change. So long as the molecular or chemical structure of the atom/substance does not change it will always be a chemical change. H20 will always be H20.
How can the classification of a mineral as an ore change?
A mineral deposit can become an ore when it becomes profitably extractable. Nevertheless, factors affecting prices include supply versus demand, production costs, stocks on hand, government (price controls), possibility of supply disruption, technology (substitution, recycling), geopolitics, and exchange rate.
What is a mineral that occurs in a quantity that is economically worthwhile to mine is called?
The mineral is found as part of the natural rock and is an ore, as in copper ore, iron ore, and so on.
Is a mineral an ore?
Not necessarily. An ore is a mineral deposit that contains some resource that can be extracted profitably. So while ores are minerals, most minerals are not ores.
Is oar like gold?
You might mean ore, and an ore is just any unrefined mineral that usually contains metal. So gold can be a part of ore, but ore does not necessarily have to contain gold.
What is a rock that contains a useful mineral?
A mineral containing a useful substance is an ore. Example: Bauxite is an ore, from which is extracted the commercially valuable metal aluminum.
Is ore and ingot a mineral?
It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.
Is diamond a mineral gem ore or other?
Diamond is an allotrope of the element carbon, so may be classified as a mineral (it can be colored by elemental impurities). About 20% of all diamonds mined are gem-quality stones, leaving the remainder to be classified as industrial diamonds. Diamond is not an ore.
What is concentration of ores called?
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal. Ores are mined from deep within the earth's crust in the form of rocks. The minerals are embedded in these rocks. The rocks are first crushed into smaller pieces by crushers. Then they are ground to powder by ball mill and other processes so that powdered ore is obtained. Depending on the type of ore, hydraulic washing, froth floatation process, magnetic separation and chemical separation techniques are applied for concentrating an ore.
Titanium ores can occur as?
Titanium ore can occur as vein mineral deposits, magma formed rocks, and beach sands.
How are minerals helpful?
Minerals are helpful for people because a iron ore is a mineral that is mined so we can use it like a iron . Thanks guys hopefully you can solve your question!

What is a gangue?
Gangue minerals are the worthless material that surrounds, or is closely mixed with a wanted mineral. - So when you extract Nickel from Nickel Ore you end up with the concentrated Nickel and also the gangue minerals which surrounded it.
