2015-04-25: Added Morrell SMC (Mia, Mib) SAB & SABC circuit model

• New specific energy model for SAG & ball mill circuits that uses Mia (from SMC™ test) and Mib (from a Bond Wi_BM) values.
• Must enter the following information for the Bond ball mill work index to permit Mib calculation in order to run this model:
  • Test P100 (closing screen) size, µm
  • Test P80 size, µm
  • Test F80 size, µm
  • Test grams per revolution (GPR)

2015-04-21: Added rod mill-ball mill circuit model

• New specific energy model using Bond/Rowland method for rod mills and ball mills.
• Fixed a problem with default values not appearing in drop-down select fields.
• Tweaked behaviour of SGI model under SAG-limited and ball-limited conditions.

2015-04-10: Added Amelunxen SGI model

• New specific energy model for SAG & ball mill circuits that uses SGI (or SPI™) values instead of Bond work index for rod mill and crushing.
• Mandatory to set the CFsag and CFball configuration factors, see the documentation.

Bug list

Known bugs that are scheduled for fixing:

• SGI model PDF output does not show the CFsag and CFball values [mostly cosmetic, low priority]
• PDF output shows the mill types as integer values rather than a description (SAG, ball, etc.) [mostly cosmetic, low priority]
