RESEARCH CONCLUSIONS

Karin Engström, LKAB

 

”Internal calculations at LKAB indicate that misclassification of ore can lead to futile extra costs of up to US$200 000 if one blast of waste is classified as ore, or loss in revenue of up to US$700 000 if one blast of ore is classified as waste.”



Pedro Carrasco, Technical Director, Codelco

 

”…I conservatively estimate that in the 2o years I have worked at Codelco, we have lost around 2.2 billion to poor sampling… ”
