The three method generally used to extract metals from ores are dependent on their reactivity. The first method is electrolysis, which is used for metals like aluminum and magnesium that have a high reactivity. The second is extraction by reaction with either carbon or carbon monoxide, which is used for less reactive metals like iron, lead and zinc. The third and final method is the use of hydrogen and this method is used for unreactive metals like gold, silver and copper. The third method is used in a variety of ways as many of these metals don't need to be separated from their ores but chemical reactions may be required to remove other contaminant materials.

What are the three major steps involved in metallurgy?
The three major steps involved in metallurgy are mining, beneficiation or ore dressing, and extraction of metal. Mining involves the removal of ore from the Earth's crust, beneficiation involves processing the raw material to improve its quality, and extraction of metal involves obtaining the pure metal from its ore through various methods like smelting or leaching.
What are the three types of metal?
Three types of metal include: iron, aluminum and gold. There are any uses for metals in society. Gold metal is extremely valuable.
What metal costs three times as much as gold?
Rhodium commonly costs about three times more than gold. It is a rare and precious metal with various industrial applications, which contributes to its high market value.
What three substances that are used to extract iron from its ore?
Coke, a form of carbon, is used as a reducing agent to convert iron ore into iron metal. Limestone is added to the iron ore in a blast furnace to remove impurities and help in forming a slag. Hot air is blown into the furnace to aid combustion and facilitate the chemical reactions necessary for extracting iron from its ore.
What metal forms 3 ions?
Iron is a metal that can form three ions: Fe2+, Fe3+, Fe4+.
What are the three general methods for passing parameters to the operating system?
Stacks, pointers and registers
What are the three gold mining methods?
Gold is recovered by three basic mining methods: placer mining of alluvial deposits, lode or vein mining, and recovery as a by-product of base-metal mining.
What are the three stages involved in extracting metal from it's mineral ore?
Smelting is a classic method of separating metals from (refining) ore. It's been around a long time. Chemical refining works well for certain metals. It came along more recently as chemistry evolved. Electro-refining depends on (what a surprise) electricity, and it is in common use nowadays.
What are the three general methods in implementing a programming language?
1- Compilation 2- Pure Interpretation 3- Hybrid Implementation System

How many general methods of energy transfer are there?
There are three general methods of energy transfer: conduction (transfer through direct contact between objects), convection (transfer through fluid motion like air or water currents), and radiation (transfer through electromagnetic waves).
What are three methods used to make alloys?
There are three common ways in creating an alloy. The first two are combining two or more melted metals and fusing two or more powdered metal through heat and pressure. The last one is the process that beams ion into the metal to make an alloy.
