In Africa, about 40% of Blacks died on the route between the areas of capture and the African coast. Another 15% died in the ships crossing the Atlantic Ocean between Africa and Brazil. From the Atlantic coast, the journey could take from 33 to 43 days. From Mozambique it could take as many as 76 days. Once in Brazil, from 10 to 12% of the slaves also died in the places where they were taken to be bought by their future masters. In consequence, only 45% of the Africans captured in Africa to become slaves in Brazil survived. Darcy Ribeiro estimated that, in this process, some 12 million Africans were captured to be brought to Brazil, even though the majority of them died before becoming slaves in the country.
