Abstract

A greatly simplified predictive liberation model has been used to generate information about the expected quantity and composition of locked middling particles, dependent on mineral grain size, particle size, ore head grade, and mineral specific gravities. This information has then been calculated for mineral systems with head grades in the range of magnetic taconite crude ore. One special "infinite dilution" case has also been evaluated which might find use with low head grade deposits such as copper and nickel sulfides. The current plan is to use these tables and relationships in developing a new and different approach to the modeling of magnetic taconite size reduction-mineral liberation.
