Curious about the phosphorus rock I mentioned earlier? Heres a little more about it from Chemistry Explained: It is possible to make pure phosphorus from phosphate rock. The rock is mixed with sand and coke (pure carbon). The mixture is then heated in an electric furnace. An electric furnace is a device for producing very high temperatures. Pure phosphorus is produced in this reaction. It escapes from the mixture as a vapor (gas). The cooled vapor solidifies into white phosphorus. The reaction is: Radioactive phosphorus helps locate the presence of tumors in the brain, eyes, breasts, and skin. This reaction is not very important because pure phosphorus has few uses. The most important compounds of phosphorus are all made from phosphate rock or calcium phosphate. Therefore, the most important step in producing phosphorus is simply to separate pure calcium phosphate from phosphate rock. This can be done fairly easily.
