Iridium Mine Production Dropping!

Global iridium production is facing a notable decline.

Key producers are experiencing significant challenges, from mine depletion to rising costs.

Here at noble6, we explore the impacts of this downturn on various industries, price stability, and potential alternative materials.

How Is Iridium Production Changing?

The global landscape of iridium production is shifting dramatically. In recent years, production levels have been on a downward trend, and this has significant implications for industries relying on this precious metal.

Overview of Global Iridium Production Levels

Recent data highlights a notable decline in iridium output. Global production dropped from approximately 7,000 kilograms in 2018 to nearly 5,800 kilograms in 2022, indicating a substantial decrease. This decline is primarily driven by several factors including mine depletions and increasing extraction costs.

Key Producers of Iridium

The iridium supply chain primarily relies on a few key players. South Africa remains the largest producer, contributing over 80% of the world’s supply. Other significant producers include Russia and Zimbabwe. Each of these regions faces unique challenges; for instance, South African mines are older and more depleted, leading to lower yields and higher costs.

Recent Trends and Data on Declining Production

Several concerning trends have emerged:

  • Rising Operational Costs: Mining operations are becoming more expensive due to deeper mining requirements and increased labor costs.
  • Mine Depletion: Many of the major iridium mines are reaching the end of their productive life. This factor alone is responsible for much of the reduction in output.
  • Geopolitical Factors: Political instability in key producing regions further disrupts production.
Fact - What Will Happen to the World's Iridium Supply?

A 2021 report by the World Platinum Investment Council (WPIC) noted that South African iridium production could face a decline of up to 20% in the next five years if current conditions persist. This is a stark indicator of the current state of the market.

These declining production levels are causing price volatility in the market. For industries that rely on iridium, such as electronics and automotive manufacturing, this can lead to increased costs.

Industries heavily reliant on iridium should consider alternative materials and recycling options to mitigate supply risks. Recycling, in particular, is becoming increasingly critical. For more insights on the importance of recycling, see our article on iridium recovery from recycling.

Given the declining availability and rising costs, companies need to focus on efficient use and explore sustainable alternatives. The viability of green hydrogen technology, for example, is tightly linked to the availability of iridium. Understanding these dynamics is crucial for planning and investment strategies.

What Is Causing the Iridium Production Drop?

Depletion of Existing Mines

The depletion of existing mines is a primary driver behind the decrease in iridium production. Many major iridium reserves, particularly those in South Africa, are experiencing diminished returns. As mines age, extracting iridium becomes more difficult and yields decrease. Older mines are typically less efficient and more expensive to operate. This directly impacts production levels and drives up costs, which are passed on to industries reliant on this metal. South Africa’s extensive mining history means many of its iridium mines are nearing the end of their productive life, creating a significant supply challenge.

Increased Production Costs

The costs associated with iridium production are also on the rise. Mining deeper into the earth to reach remaining iridium reserves increases both labor and equipment expenses. The energy required for deeper mining operations adds another layer of cost. Furthermore, logistics expenses rise as mines move farther from transport hubs. Operations in remote regions compound these costs, making it harder for producers to maintain profitability. These increased production costs are contributing to price volatility in the iridium market.

Environmental Regulations and Restrictions

Environmental regulations and restrictions are playing an increasing role in the decline of iridium production. Governments worldwide are implementing stricter environmental standards to reduce the ecological impact of mining. These standards often require companies to implement costly measures to reduce emissions and manage waste. In some cases, regulations can lead to the slow-down or even closure of existing operations. For example, South African mines have faced regulatory scrutiny that has forced them to adopt more sustainable but expensive practices. Stricter environmental policies in these key regions are unavoidable and contribute to the dwindling output of iridium. For more details on how environmental factors influence mining, see our article on sustainability and recycling.

Actionable Insights

Industries dependent on iridium must consider immediate actions to address these challenges. Exploring alternative materials is essential. For example, ruthenium and platinum could serve as substitutes in some applications. Enhancing recycling programs is another actionable step. Recycling initiatives can reclaim iridium from end-of-life products like spark plugs, lessening the strain on natural reserves. Companies might also invest in research and development to create more efficient iridium use processes, reducing dependency on mining operations. Long-term planning should integrate these alternatives for a more sustainable and cost-effective approach to iridium usage.

Fact - Why Is Iridium Production Dropping?

How Will Declining Iridium Impact Industries?

The reduction in iridium production has a ripple effect across multiple sectors, notably the automotive and electronics industries. Both industries depend heavily on iridium for manufacturing critical components such as spark plugs and electrical contacts.

Effects on Automotive and Electronics Industries

In the automotive sector, iridium is key for producing durable spark plugs, which last up to 25% longer than those made with other metals. With dwindling iridium supplies, manufacturers may face increased production costs or delays in supply chains. The electronics industry also relies on iridium for its excellent conductivity and resistance to corrosion, vital for high-performance electronics. These shortages can push companies to halt production or innovate under pressure, as the average cost of iridium in electronic components has already surged by 30% in recent years.

Price Fluctuations and Market Stability

Iridium prices are notoriously volatile, often reacting to shifts in production and geopolitical instability. Prices spiked by over 160% between 2020 and 2021 due to increased demand from the green hydrogen sector and pandemic-related supply chain disruptions. Industries that don’t prepare for such volatility risk budgeting inaccuracies and financial losses. Companies should adopt advanced market prediction tools and lock in long-term supplier contracts to stabilize costs.

Alternative Materials and Substitutes

Seeking alternative materials is imperative. Ruthenium and platinum can replace iridium in some applications, although each substitute comes with trade-offs in cost and performance. The push towards recycling is another viable strategy. Recycling initiatives can recover up to 90% of iridium from used electronics and automotive components, a significant boost considering the tight supply. Investing in new technologies for more efficient metal use is necessary to mitigate these risks.

Fact - Why Choose Iridium?

For a broader perspective on how the green hydrogen industry intersects with metal demands, see iridium’s role in hydrogen production.

Companies facing these challenges must prioritize adaptive strategies and alternative materials to navigate the uncertain landscape shaped by iridium’s dwindling production. The stakes are high, but proactive measures can help industries remain resilient.


Our deep dive into iridium’s declining production reveals some pressing realities. A substantial drop in global output is causing widespread disruption across multiple industries. The data shows a fall from 7,000 kilograms in 2018 to around 5,800 kilograms in 2022. This reduction stems from mine depletion, rising operational costs, and tighter environmental regulations.

Fact - How Can Industries Combat Iridium Scarcity?

For the future market, we expect continued volatility in iridium prices. Industries reliant on this metal, such as automotive and electronics manufacturing, will face higher costs and potential supply chain challenges.
