Application of Large Diameter Coring Technology in Beneficiation and Metallurgy Test of a Mining Area in RDC

Abstract:

In order to meet the needs in quality of core sample for the beneficiation and metallurgy test, the coring drilling technology with large diameter（≥φ325mm） tubular was used in Sicomines copper-cobalt mining area. The key to the success in the large diameter coring project lies on selecting different tubular-shaped drilling tools and coring technologies according to the condition of complete or broken formation.
