The Bond Work Index of Limestone and Andesite Mixtures

Ore grindability is represented by the Bond work index value for the purposes of the processes in mineral processing. This value is found in a laboratory Bond ball mill by simulating dry grinding in a closed circuit until the 250% circulating load has been achieved (Magdalinovic, 2003).

Bond Work Index Formula-Equation - Mineral Processing & Metallurgy

When Erf/Erp is greater than 1.29, the work index increases as the product size decreases, and when Erf/Erp is less than 1.29 the work index decreases. Eq. (8) suggests that a standard work index Wi100, or the work index at 80% passing 100 microns calculated from the exposure ratios, can be found from the following Eq. (9):
