With an increasing mining production, the extractable ores of the world’s geologically scarcest mineral resources (e.g. antimony, molybdenum and zinc) may be exhausted within several decades to a century [Citation 4]. Similarly, other ores will be depleted one by one through mining operation sooner or later in the future.

Heap leaching - Wikipedia
Gold heap leaching. Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore

Molybdenum metal alloys
Molybdenum metal is usually produced by powder metallurgy techniques in which Mo powder is hydrostratically compacted and sintered at about 2100°C. Hot working is done in the 870-1260°C range. Moly forms a volatile oxide when heated in air above about 600°C and therefore high temperature applications are limited to non-oxidizing or vacuum
