Gold mineralisation at Ana Paula is associated with arsenopyrite and pyrite hosted in a highgrade hydrothermal breccia. The dominant mineralisation occurring at the project is epithermal with brecciation appearing at contact zones. ... The processing will include crushing followed by closedcircuit ball mill and gravity concentration.

Epithermal gold deposits are among the richest gold deposits in the world, with some bonanzagrade ore shoots containing more than 1000 g/t goldequivalent or a kilogram of gold for everyone tonne of rock mined. The tonnage of ore in epithermal veins is typically smaller than other types of lowgrade gold deposits.. Gold mineralisation within epithermal veins can occur over vertical intervals ...

Ore processing at Kinross Gold Corporation's project. Ore processing starts with a precrushing circuit including a semiautogenous ball mill. This is followed by primary crushing in two ball mills where the ore size is further reduced. Crushed ore is ground into a fine powder in the grinding circuit.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
