A potential application of high voltage pulse technology

A novel comminution circuit was designed, which incorporated SELFRAG to pre-condition part of SAG mill feed (9.5 to 150 mm) and to treat the circulating SAG mill pebbles. The high voltage pulse technology effectively reduced the amount of u27critical sizeu27 particles in the SAG mill and pre-weakened particle strength for grinding.

Ore processing – Waihi Gold

The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.

Application of Operating Work Indices in Autogenous

1 presents AG/SAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi, the calculated figures would suggest that the AG/SAG (AG-SAG)/ball mill circuit, but they are of limited value in evaluating AG-SAG and ball mill sections separately. This problem arises due to the difficulty of
