They promote: i) the oxidation of the sulphide matrix, rendering gold more accessible to the leaching solution; ii) gold stabilisation, a result of the formation of gold-rich complexes and/or colloids; and iii) gold solubilisation by enhancing the permeability of ore bodies (Amachi, 2008; Brehm et al., 2005; Burford et al., 2003; Hilson and ...
Standard Bond Ball Mill Grindability Test Method-Procedure
When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the opening in microns of the sieve size tested, then ball mill work index Wi is calculated from the following revised (1960) equation:
How Ball Mill Ore Feed Size Affects Tonnage & Capacity
For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
Caribel Mine
By 1917 there was a five story cyanide mill containing a five-stamp crusher, a ball mill, and a large separator. In addition to the usual buildings - bunk houses, office, cook shack, assay office, blacksmith shop, there was housing for families of some of the miners. At its peak, a total of 30-40 men were working the mine, often in three shifts.
