“Over one million tonnes of cobalt from 1773- 1898”, page-4

Modern production of largest cobalt miners per annum are below.
~8000t per year average for that historical largest cobalt mine in the world at the time is not wrong.


1. KamotoTotal 2020 production: 23,900 tonnes

The Kamoto copper-cobalt mine, which is located in the DRC province of Katanga, is operated by Glencore (LSE:GLEN,OTC Pink:GLCNF) subsidiary Katanga Mining.Katanga’s cobalt production was up 40 percent in 2020 over the previous year. Production at Kamoto has been incrementally increasing since commercial operations first began in 2007.In early 2021, Glencore inked a five year supply contract for cobalt hydroxide from Kamoto with cobalt refiner First Cobalt (TSXV:FCC,OTCQX:FTSSF).

2. Tenke FungurumeTotal 2020 production: 15,440 tonnes

Tenke Fungurume, located in the DRC’s Lualaba province, is 80 percent owned by China Molybdenum (OTC Pink:CMCLF,SHA:603993) and 20 percent owned by state mining company Gecamines.Tenke Fungurume has been struggling to meet production targets due to falling metal prices combined with higher taxes and royalties in the African country. Production in 2020 fell by more than 650 tonnes from 2019 levels. In addition to its cobalt output, the mine is the DRC’s largest copper producer.

3. Metalkol RTRTotal 2020 production: 10,500 tonnes

The Metalkol RTR hydrometallurgical cobalt and copper facility, which is located in the DRC’s Haut-Katanga province, is operated by Eurasian Resources Group (ERG) Africa.Metalkol RTR reprocesses historical cobalt-copper tailings that were accumulated over decades of mining by previous operators. This includes the existing Kingamyambo tailings deposit and those in the Musonoi River. The goal is to reduce local pollution by relocating legacy tailings to a responsibly managed facility.
