What is a major factor causing fluctuations in silver supply that affects its industrial use?
Silver is primarily mined independently, so its supply is stable regardless of other metals.
Silver is mostly produced as a byproduct of refining other metals, linking its supply to their production levels.
Silver supply is controlled solely by government stockpiles, not by mining or refining processes.
