What else can I help you with?
If a mineral can be scratched by a fingernail but not by a pocket knife what does that tell us about the mineral?
It would have a Mohs hardness somewhere between 2.5 and 5.5.
Mineral based fluxes welding?
Mineral-based fluxes are commonly used in welding to facilitate the joining of metals by removing oxides and impurities from the surfaces, promoting wetting, and preventing oxidation during the welding process. These fluxes are composed of mineral compounds such as borax, fluoride, and chloride, which lower the melting point of the oxide layers and help to create a clean and strong weld. Different types of mineral-based fluxes are used based on the specific requirements of the welding application, such as soldering, brazing, or welding different metals.
How Which property might you test by rubbing one minerals directly against another and?
You can test the hardness of minerals by rubbing one mineral against another. This method helps determine which mineral is harder based on whether it scratches the other. The Mohs scale of mineral hardness is often used to classify minerals based on their ability to scratch one another. For example, if a mineral can scratch a known mineral like talc (hardness 1), it is likely harder than talc.
What is the main source of mineral salts?
Mineral salts are mainly sourced from natural elements in the soil and water. Plants absorb these minerals from the soil, and animals obtain them from the plants they consume. Additionally, mineral salts can also be found in natural sources like rocks and sea water.
Is mineral spirits conductive?
No, mineral spirits are not conductive. They are non-conductive solvents commonly used for cleaning and thinning oil-based products like paint, stain, and varnish.
What are advantages of mineral based industry?
Iron and steel, cement, aluminum, machine tools, petrochemicals producing industries are called mineral based industries.Mineral based industries are primary industries that use mineral ores as their raw materials. The products of these industries feed other industries. Iron made from iron ore is the product of mineral based industry. This is used as raw material for the manufacture of a number of other products, such as heavy machinery, building materials and railway coaches.
What is the difference between Agro-based and Mineral-based industry?
Agro-based industry derive their raw material mainly from agriculture,using animals.Products can be considered as raw material directly.Mineral-based industry derive their raw materials from mining,using human labours.Products can be considered as raw material only after purification
When was National School of Mineral Industry created?
National School of Mineral Industry was created in 1972.
What is Ohio's oldest mineral industry?

What are the other inputs in the process of manufacturing in agro based and mineral based industries that involve transportation cost?
Agro based industry include all terms.One input is Raw material-In raw material all includes .Industries may be agrobased,mineral based,mariene based and forest based depending on the type of raw materials they use.

State two uses of mineral acids in industry?
Mineral acids are used in industry for metal cleaning and pickling processes to remove rust and scale from surfaces. They are also used in the production of fertilizers, where sulfuric acid is a key component for manufacturing phosphate and nitrogen-based fertilizers.
What are the uses of mineral oils in industry?
Minerals have many uses in different industries. Mineral oils are used in the mechanical industry as a lubricant. Minerals oils are used in the cosmetics industry as an ingredient in such things as baby oils and lotions.
What industry is based on the natural resource of trees?
The industry that is based on the natural resource of trees is the forestry industry.
Do some alien races have mineral-based characteristics?
Some alien races could have mineral based characteristics, if they exist.
What is an Agro-based industry?
It is based on agriculture.
