how many antimony smelters outside China are there?

The Critical Midstream registry lists 52 plants matching this query across 20 countries. Each record carries a source, a verification date and a confidence level.

how does Critical Midstream verify these records?

Every record links its own evidence — a government register, a company filing, an announcement or reputable trade press — with a verification date and a correction route. A reviewer signs off before a record claims verified.

what's the difference between nameplate capacity and actual output?

Nameplate capacity is a plant's designed maximum. Actual output is what it really produces. Critical Midstream flags which figure a record shows and never conflates the two.
