Which ores are used in making various kinds of steel?
hematite and wolframite..
Various iron ores are used (e.g. magnetite, hematite, goethite, limonite, siderite) to start with. That is mixed with limestone and coke in a blast furnace to make cast iron. The cast iron is then put in a Basic Oxygen Process furnace to burn off the excess carbon and you get carbon steel. There are other slightly different processes that can be used and various other alloying elements can be added to get a steel with…
What is a mineral called it if it is considered valuable and can be made into something such as steel?
Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight. Carbon is the most 'cost effective' (highest 'added value') alloying material for iron, but various other alloying elements are used, such as nickel, manganese, chromium in RVS, tungsten in HSS steel, and some others. So you'll have to look for some more mineral ores, but carbon is not a mineral.
Many of the metals that humans use come from ores. For example the iron used to make steel comes from the the mineral hematite, lead for batteries is produced from galena, and the magnesium used in vitamins comes from dolomite. Ores of these useful metals must be extracted from Earth in a process called mining.
