What Ledoux & Co. does

Ledoux & Co. is a commercial metallurgical testing laboratory founded in 1880 and headquartered in Teaneck, New Jersey, operating as a family-owned private business with 11–50 employees. The company performs elemental analysis on precious metals, base metals, ores, concentrates, catalysts, and electronic scrap, serving mining companies, catalyst recyclers and manufacturers, refineries, and electronic scrap processors worldwide. Its analytical capabilities rest on three methodological pillars — fire assay, classical wet chemistry, and instrumental analysis (including Inductively Coupled Plasma spectroscopy and gravimetric determination) — delivered under ISO/IEC 17025 ANAB accreditation and ISO 9001:2015 quality management certification, with results accepted for umpire, control, and financial-exchange purposes.

The company's service portfolio comprises six integrated lines: Catalyst Testing, Precious Metals Analysis, Copper Concentrates Testing, Electronic Scrap Analysis, Rare Earth Elements Analysis, and On-Site Precious Metals Representation, where technicians witness weighing and sampling at customer processing facilities. Revenue is generated through professional laboratory testing fees billed on a quote-based, pay-as-you-go basis, with customers submitting samples via web or PDF forms. The go-to-market motion is sales-led and B2B, relying on direct engagement, sample-submission workflows, industry association memberships (IPMI, LBMA, LPM), and a content-marketing blog that publishes educational material on metallurgical testing topics.

Customer-facing operations span North America at minimum, with a dedicated Mexico-locale website indicating active outreach into Latin American mining and refining markets. The firm leverages 145+ years of brand heritage — including historical analyses of the Statue of Liberty's copper, Chrysler Building metals, Brooklyn Bridge cables, 1969 Apollo lunar samples, and Manhattan Project-era Hudson River monitoring — alongside industry memberships and accreditation credentials as primary differentiators. No external funding, M&A, leadership changes, or public-company signals appear in the source data, and the company has no public API, mobile app, or disclosed AI/ML capabilities.
