Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth''s crust is called a mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.
With a solid reactant the amount of its surface that is available is a very important factor. If the solid is finely powdered its surface area will be very high and therefore more molecules can collide with each other, and the rate of reaction will increase. The final major factor that affects the rate of reaction is the temperature used.
