Iron = duodenum
Folate = jejunum (intestinal conjugase)
B12 = ileum
Folate absorption decreased with oral contraceptives, alcohol, phenytoin, pure vegan diet
B12 absoprtion decreased with bacterial overgrowth, pernicious anemia, Crohn's disease

Vitamin B12 is absorbed in the ileum (with IF being broken down after it splits from the vitamin B12), folate is absorbed in the jejunum (?), and iron is absorbed primarily in the duodenum. Calcium is absorbed throughout the whole intestine, I believe.
