from seven mines located in Western and South Australia. The nine sets of nickel tailings data were obtained from Western Australian nickel sulphide mines with both 'oxide ore and fresh hard rock ore. In addition, selected data from tantalite mine tailings and aluminum tailings in Western Australia are presented.

studied include mill rotational speed, ball size, mill I charge and wet versus dry grinding. Breakage rates have been determined experimentally utilizing a SEM—IPS image analyzer. The mineral sample used was acquired from ASARCO's Young Mine which is located in Jefferson City Tennessee. It was a binary ore consisting of sphalerite and dolomite.

of the mine can easily be derived. 1. Example. For the iron ore unit we assume a price of 0.35 $/u. Accordingly, a mine producing high grade direct shipping ore of 64% Fe has a revenue of 64 • 0.35 = 22.40 $/t iron ore. To arrive at the return f.o.b. mine (free on board, see Chap. 9.4.1) freight costs have to be subtracted. 2. Example.
