mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...

a chemical change is something that can not be reversed, so you may think crushing a rock but it isn't because crushing a rock is a phisical change not chemical and if you freeze water you can melt it and of you melt ice you can freeze it, so those can be reversed. So the answer is B because that can not be reversed

Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.

Why Dissolving Salt Is a Chemical Change. When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products ...

All chemical reactions are reversible although this can be difficult in practice. Many junior school science texts state that chemical changes are irreversible while physical changes can be reversed. Cutting paper into tiny pieces or crushing a rock are obvious physical changes but to restore the original piece of paper or rock is difficult.

Table 12.1 lists some commonly analyzed radioisotopes, their volatile chemical form, and the boiling point of that species at standard pressure. Note that the boiling point may vary depending upon solution, matrix, etc. Often the moisture content, and thus, the chemical composition of a solid is altered during grinding and crushing (Dean, 1995).

(Q)which of the following describes a chemical change (A) a. melting ice b. freezing water c. crushing rock d. lighting a match - 8099978

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

A change in which one or more new substances are formed is known as chemical change. For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction. The colour of the surface of the iron also changes. Hence, rusting of iron is a chemical change.
