The CaCo3 mine, which was extracted by Kuruçayırlı Madencilik in Çaydurt district of Bolu province, started to be exported to Australia, Belgium and the Netherlands to be used as a pharmaceutical raw material.

Micronized and packaged in Kuruçayırlı Mining Çaydurt Facilities, the mine set off from Gebze port. CaCo3, which comes out of the quarry with a micronized processing capacity of 13 tons per day and a production capacity of 200 tons, serves many different sectors other than the pharmaceutical industry.
