The Flow Sheet of the Coons-Pacific Iron Ore Concentrator (Mining World, July 1953, pp. 45). The design of the Coons-Pacific flow sheet allowed so "that any time any size fraction may be rejected, sent to a concentrating section, or loaded as a concentrate. In essence, the entire plant has the flexibility of a laboratory."

Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.
