Indium (In) is a chemical element and a soft, silvery-white metal. It is known for its high ductility and malleability. It is one of the softest metals and has a very low melting point. Its most important use is in making Indium Tin Oxide (ITO) for touchscreens and other displays. This makes Indium a vital material for modern electronics.
 

Its industrial applications, with estimated industry-wise proportion, are as follows:

• Electronics and Displays (60-70%): Indium is the main raw material for Indium Tin Oxide (ITO). ITO is a transparent conductive coating used in liquid crystal displays (LCDs), OLED screens, and touch panels.
• Solders and Alloys (10-15%): Indium alloys have a low melting point, which makes them ideal for solders and special alloys used in electronics and medical devices. They are mainly useful for applications where lower temperatures are needed.
• Solar Cells (5-10%): Indium is a component in CIGS (Copper Indium Gallium Selenide) solar cells. These are a type of thin-film photovoltaic technology.
• Semiconductors and Research (3-5%): Indium is used as a dopant in semiconductors. It is also used in infrared detectors and other high-tech applications.
• Other Speciality Uses (2-5%): This includes minor applications in bearings, seals, corrosion protection, and as a component in dental alloys.

Feedstock for Indium and Value Chain Dynamics

The industrial process for producing Indium starts with zinc ores, where Indium is present as a minor component. Initially, zinc is recovered using the Waelz process. After this, the extraction and purification of Indium involve hydrometallurgical methods and electrolytic refining.

• Zinc Ore Sourcing: The primary feedstock is zinc ore, with Indium being a trace element. Major mining operations are in geo-locations like China, Peru, Australia, and the United States.
  • Mining Costs and Volatility: The cost of this raw material is tied to the high capital investment costs of mining and refining zinc ore. Indium is a byproduct, so its supply is inelastic. It is not produced based on its own demand. This makes its price highly susceptible to market price fluctuations in the broader zinc market.
• Waelz Process: This is an initial high-temperature step. It separates zinc and other volatile metals from the ore concentrate.
  • Energy-Intensive Step: The Waelz kiln operates at high temperatures (over 1000 degree Celsius). Fuel and electricity for this process are a major part of operating expenses (OPEX).
  • Residue Management: Indium remains in the zinc-rich residue from this process. This residue is the direct feedstock for Indium recovery.
• Leaching and Electrolysis: These are the chemical and electrochemical steps used to isolate Indium.
  • Chemical Reagents: The process requires various acids (e.g., sulfuric acid, hydrochloric acid) and other chemicals for leaching and purification. The costs of these reagents add to manufacturing expenses.
  • Electrolysis Energy: The electrolysis of zinc to obtain Indium as a residue is an energy-intensive process. The cost of electricity is a major factor in the production cost analysis.
• Byproduct Management: The main product of the upstream process is zinc.
  • Byproduct Revenue: The value recovered from the primary product, zinc, is the main source of revenue for the plant. This revenue significantly offsets the high manufacturing expenses for the entire operation. The value of Indium is then a crucial secondary factor in the overall cost model.
     

Market Drivers for Indium

• Growth in Electronics and Displays: The increasing global demand for smartphones, tablets, computers, and large-screen TVs drives a huge need for Indium Tin Oxide (ITO). ITO is the transparent conductor used in all touchscreens and most flat-panel displays. This translates into substantial demand, directly impacting the Indium plant capital cost associated with establishing or expanding production units.
• Expansion of Solar Panel Manufacturing: The solar energy sector is growing fast. The increasing demand for thin-film CIGS solar cells, which use Indium, supports a steady consumption of Indium.
• Speciality Solders and Alloys: Indium's low melting point makes it ideal for speciality solders in electronics. This ensures its continued demand in the high-tech assembly and manufacturing sectors.
• Supply Constraints: Indium is an extremely rare element. Its supply is limited and dependent on the mining and refining of zinc. This inelastic supply, combined with rising demand, leads to significant market price fluctuation.
• Regional Production and Consumption Patterns:
  • China: China is the largest producer of Indium, largely due to its significant zinc mining operations. It is also a major consumer due to its dominant role in electronics and display manufacturing. The Indium manufacturing plant cost here is often integrated with existing zinc refining.
  • South Korea, Japan, and Taiwan: These geo-locations are key consumers of Indium for their advanced electronics and display industries. Capital investment (CAPEX) in these regions often prioritises the manufacturing of end-products rather than primary Indium refining.
  • North America and Europe: These regions have a stable demand for high-quality Indium for electronics, solar, and speciality applications.

Manufacturing Process of Indium

This report comprises a thorough value chain evaluation for Indium manufacturing and consists of an in-depth production cost analysis revolving around industrial Indium manufacturing. The process recovers Indium from zinc ore.

• Production from Zinc Ore via the Waelz Process:The industrial manufacturing process of Indium starts with zinc ores. Indium is initially obtained as a residue during the Waelz process. This is a high-temperature process used for the recovery of zinc from low-grade ores. The Indium-rich residue is then subjected to leaching and purification. This is followed by the electrolysis of zinc. During this electrolysis, Indium is left as a residue. It is from this final residue that pure Indium is produced.
