Special warranty deeds are becoming more common. A general warranty deed is a promise to the buyer that the seller will warranty any prior problems.
Cobalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes. There is no evidence of cobalt deficiency in human beings, and no evidence on which to base estimates of requirements for inorganic cobalt.obalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes.

Cobalt is a chemical element with symbol Co and atomic number 27. Like nickel, cobalt in the Earth's crust is found only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.oday, some cobalt is produced specifically from various metallic-lustered ores, for example cobaltite (Co As S), but the main source of the element is as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo and Zambia yields most of the cobalt mined worldwide.
