IS GOLD rare or valuable?
Gold is valuable BECAUSE it is rare and it is useful. it doesn't corrode like iron (via rust), it conducts both heat and electricity well and is ductile (soft and workable.)
If you rub a mineral against a piece of porcelain tile what does this procedure tests the of the mineral?
Rubbing the mineral against an unglazed ceramic tile, called a streak plate, leaves a streak of the powdered mineral. This powder reflects the true color of the mineral. It's called a streak test, and the resultant line of color is called the streak. A link can be found below to check facts and learn more.
Which article should be used before the word useful?
Article before the word useful
What property of ceramics makes them useful as oven walls or as insulating materials?
a discovery made thousands of years ago increased the usefulness of dried clay objects. Heating clay to about 1,000 celcius makes it harder and stronger. ceramics are hard, crystalline solids made by heating clay and other mineral materials to high ctemperturs
Why is an earthquakes risk map useful?
They're not.
A mineral is classified as an ore as long as?
It is considered an ore as long as the locallized concentration of the mineral exceeds its crustal abondance.
Is a mineral an ore or a gem if it contains something useful and can be sold for a profit?
Actually, a mineral is an ore if it contains another mineral. It can also be sold for a profit, once the USEFUL mineral is either melted out, or drilled out. Then the left over of the ore is useless, but the mineral itself can be sold for profit purposes.
What is a mineral that contain enough of a useful substance that it can be mined at a profit?
An example of such a mineral is bauxite, which is a source of aluminum. Bauxite is mined at a profit because the aluminum extracted from it is highly valuable in industries such as aerospace, construction, and transportation. This makes bauxite a commercially viable mineral to mine.
What mineral became valuable and useful to man most recently?
Rhodium
What is always a property of an ore?
A property of an ore is that it contains a valuable or useful material that can be mined and extracted profitably.
A rock that contains a metal or other useful mineral that can be mined and sold at a profit is called?
The rock is called an ore. Ores are rocks that contain minerals with high concentrations of valuable elements or metals that can be extracted and processed for commercial use.
When is the term ore used with reference to mineral?
The term "ore" is used to refer to a mineral or rock from which a valuable or useful substance, typically metal, can be extracted profitably. Ores are important sources of metals and serve as the primary sources for many industrial processes.
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.
What are the steps for ore to be a useful product?
Mining: Ore is extracted from the earth. Processing: The ore is processed to extract the valuable minerals. Refining: The extracted minerals are further purified to remove impurities. Manufacturing: The refined minerals are used to create useful products.
What are facts about fool's gold?
It is Iron Sulfide and actually quite a useful mineral - just not as valuable as gold.
What is the relationship between mineral ore and gangue?
Mineral ore is the valuable material that can be extracted and processed for its useful properties, while gangue is the unwanted material that is typically separated from the ore during the extraction process. Gangue does not have any economic value and is usually discarded as waste material. The relationship between mineral ore and gangue is that they are often found together in the same rock or ore deposit, with the goal of separating the valuable ore from the gangue to extract the desired minerals.
What is the process of extracting a useful substance from an ore?
The process of extracting a useful substance from an ore typically involves crushing the ore to release the desired mineral, then separating the mineral from the gangue (unwanted material) using physical or chemical methods such as gravity separation, flotation, or leaching. Finally, the extracted mineral is further refined to obtain the desired substance in its pure form.
