fused or melted) and </span></span>ductile<span> (able to be
drawn out into a thin wire). About 91 of the 118 elements in the </span>periodic

An ore is an experience of rock or sediment that comprises sufficient minerals with economically valuable elements, typically metals, that can be economically derived from the deposit. The ores are obtained from the earth through mining; they are then polished (often via smelting) to extract the important element or elements.A metal is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.
