Abstract. "Nitrophosphate" is a generally accepted term for any fertilizer that is produced by a process involving treatment of phosphate rock with nitric acid. The term "nitric phosphate" has been used to some extent, particularly by TVA, but on a worldwide basis "nitrophosphate" seems to be more generally accepted.
ning of the process to handle the phosphate rock in hydro transport or in the initial ball mill circuits for sizing the rock. These pumps handle a concentration of 40-55% solids by weight where abrasion and erosion wear are the primary concern. Particle size, hardness, shape, specific gravity, concentration, and operating conditions are key factors
