Overview
Indium ingot is refined indium cast into small bars, the standard tradeable form of a metal that most people have never heard of despite touching it almost every day — indium tin oxide, the transparent conductive coating made largely from indium, is what makes touchscreens on phones, tablets and laptops actually work, allowing a screen to be both see-through and electrically responsive to a fingertip.
Production as a Byproduct Metal
Indium is almost never mined on its own; it occurs in trace concentrations within zinc ores and is recovered as a byproduct during zinc smelting and refining, with smaller amounts also recovered from lead and tin processing. That byproduct status is the single most important thing to understand about indium supply: mining companies don't decide to produce more indium in response to a higher indium price the way they might for a primary metal, because indium output is tied to how much zinc ore gets processed, not to indium economics on its own. That structural link is a major reason indium supply can be slow to respond even to a sharp price increase — smelters would need to process significantly more zinc ore, for reasons that have nothing to do with indium, before meaningfully more indium becomes available.
Applications and Demand Drivers
Beyond touchscreen coatings, indium tin oxide is also used in solar panel manufacturing and in various optoelectronic and semiconductor applications, giving indium demand two structurally growing end markets — consumer electronics and renewable energy — pulling in the same direction at once. Because global indium supply is both small in absolute volume and tightly bound to zinc refining capacity, sudden increases in demand, such as a surge in electronics manufacturing, can move indium prices sharply, in percentage terms, more than would typically be seen in larger, more liquid industrial metals.
