Metallurgic Processes | Boundless Chemistry
Metal ores are generally oxides, sulfides and silies of “native” metals (such as native copper) that are not commonly concentrated in the Earth’s crust. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis.
25.2: Properties of Transition Metals - Chemistry LibreTexts
However, like the ions of the more active main group metals, ions of the f-block elements must be isolated by electrolysis or by reduction with an active metal such as calcium. We shall discuss the processes used for the isolation of iron, copper, and silver because these three processes illustrate the principal means of isolating most of the d -block metals.
Heavy metals - Wikipedia
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic nuers.The criteria used, and whether metalloids are included, vary depending on the author and context.  In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic nuer, while a chemist would likely
Reactivity Series of Metals - Get the Chart, Significance …
In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.

Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired
