Phosphate Mining

Most mining of phosphate rock involves clearing large swaths of vegetation and digging up the soil beneath to reach the phosphate-ore-containing matrix 60 to 80 feet below the surface. This matrix is then transported by pipeline to a nearby plant, where the phosphate ore is forcibly separated from the sand and clay by a process known as ...
