The basic work index equation is: W = 10 Wi/√P – 10 Wi/√F………………………………………………………………………… (1) where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work index, or the grinding resistance parameter.
Unusually shaped materials (e.g., mica) should be regarded with caution. The Bond Work Index (Wi) is the specific energy associated with a stan- dard amount of size reduction: from a very large F80 (80% passing circuit feed) of approximately infinity …

Soil fractions are treated with the J. Lawrence Smith Na 2 S 2 O 7 fusion which is shown to decompose micas and other layer silicates common in soils. The layer silicate relics are dissolved by washing with 3 n HCl and hot 0.5 n NaOH for 2.5 min leaving quartz and feldspar in the residue. Recovery of quartz after the treatment ranged from 99.4% in the 50 to 20µ fraction to …
