Too much iron will usually turn the blood black. However, if there is liver failure, and it's seeping into the blood stream that too can cause the blood to turn black as it becomes over loaded with toxins. Put simply it's the blood is overloaded with toxins and other nutrients that the body can't process entirely.

Blood appears black when it is deoxygenated because the hemoglobin in red blood cells changes its molecular structure when it releases oxygen. This change causes the color of the blood to appear darker.
