SO i thought to myself, what the hell is CVRD. here is what i learned from WIKO (Wikopedia). 

Companhia Vale do Rio Doce (CVRD) is a global diversified mining company, the second largest mining company in the world, and the largest logistics operator in Brazil. Founded in 1942 in Itabira as a public company, it became the leader in production and exportation of iron ore and pellets (in a process called pelletizing). CVRD is also a world-class producer of nickel, manganese, ferroalloys, copper concentrate, bauxite, potash, kaolin, alumina and aluminum.

Besides being the largest Brazilian logistics services provider, CVRD is recognized for its excellence in the elaboration of complete logistic solutions for national and foreign customers, integrating many Company-owned assets, such as railroads, ports and maritime terminals with partner’s assets and also offering coastal sea route delivery services. In the electric energy sector, the Company participates in consortia, presently operating four hydroelectric plants to assure the power supply for CVRD operational activities.
