In chemistry, reduction is defined as a phenomenon in which substance gets electron from other species, oxidation is defined as a process in which substance donates electron to other species. When a metal acts as reducing agent, the other substance (for which metal acts as reducing agent) gets electrons (from metal) and by definition goes on reduction, and the metal, in this process, donates electron so, metal itself undergoes to oxidation.

As a reducing agent reduces another substance, it itself is oxidized. This means it loses electrons and becomes oxidized. The reducing agent transfers its electrons to the substance being reduced, causing the reduction of that substance.
Metals usually have 1,2 or 3 electrons in their valence shells. during a chemical reaction, metals have the more probability of loosing the valence electron(s) and hence becomes electropositive ions for which it is also know as a reducing agent.
As a reducing agent reduces, it oxidizes another substance. During this oxidization process, the other substance gains electrons and the reducing agent loses electrons.

Gold is a reducing agent because it tends to lose electrons and undergo reduction reactions, in which it reduces other substances by donating electrons.
A reducing agent is used in metallurgy to remove oxygen from metal ores during the process of extraction. It provides electrons to the metal ions in the ore, which reduces them to their elemental form. Common reducing agents include carbon, carbon monoxide, and hydrogen.
Yes, LiAlH4 is a reducing agent.
