In automotive catalytic converters, rhodium is primarily used for which function?

Reducing nitrogen oxides (NOx) to N2

Which of these has been a major driver of rhodium price spikes in recent decades?

Increased use in smartphone batteries

Higher demand for catalytic converters

Large-scale primary rhodium mining projects

Replacement by cheaper metals in industry

A common supply-side risk that has contributed to rhodium price volatility is:

Abundant new deposits discovered in multiple countries

Rhodium being easily synthesized artificially

Labor strikes and mine disruptions in South Africa

Rapid substitution of rhodium in catalysts

Aside from new mine production, what significant secondary source affects rhodium supply?

Recycling of automotive catalytic converters

Electroplating waste from the semiconductor industry

Which statement best describes rhodium's abundance and price relative to other precious metals?

Very abundant and cheaper than silver

Extremely rare and often much pricier than gold

About as common as copper and similarly priced

Commonly traded like uranium futures
