Metals Flashcards
a naturally occurring substance with a range of chemical composition.
Mineral
A mineral deposit concentrated enough to allow economical recovery of a desired metal
Ore
a naturally occurring mineral containing a valuable constituent
Ore
a source from which valuable matter is extracted.
Ore
Naturally occurring substances present in the earth’s crust
Minerals
It has a well-defined compound structure that occurs in pure form
Mineral
The three principal steps in the recovery of a metal from its ore
preparation of the ore
production of the metal
purification of the metal
Minerals obtaining metals
ore
The science and technology of separating metals from their ores and of compounding alloys.
Metallurgy
a solid solution either of two or more metals, or of metals with nonmetals.
alloy
metallic substance composed of two or more elements, as either a compound or a solution.
Alloy
In this process, the ore is finely ground and added to water containing oil and detergent.
Flotation
In flotation, the liquid mixture is then beaten or blown to form a ____
froth
In getting the metal from the ore, waste materials, usually clay and silicate minerals, are left. What are those waste materials called?
Gangue
Example of a ferromagnetic metal
cobalt
an alloy of mercury with another metal or metals.
Amalgam
What metals does mercury NOT form with to have an amalgam?
Iron
Platinum
Tungsten
Tantalum
It is the extraction and purification method of iron metal from its respective ores, followed by the conversion of pure iron metal into steel and other alloys.
Metallurgy of Iron
It begins with the processing of ores to extract the metal, and includes the mixture of metals to make alloys.
metal production
It is made from iron ore, a compound of iron, oxygen and other minerals that
occurs in nature.
Steel
One of several methods used in steelmaking
Oxygen Process
These are particularly suitable for the extraction of iron.
hermatite and magnetite
Iron extracted in this way contains many impurities and is called ______
pig iron (cast iron)
Three common purification procedures for metals
Distillation
Electrolysis
Zone Refining
