Project Summary

In 2007, the first modernization phase commenced. The initial phase included the construction of a 34 foot semi-autogenous grinding (SAG) mill, conversion of rod mills to ball mills and the complete replacement of the flotation recovery system with 160m3 float cells, along with the addition of new mining equipment.

Coarse gangue rejection essentially uses flotation cells as an ore sorting technology. "It's an ore sorting technology, except it sorts material at maybe half a millimeter, as opposed to conventional sensor-based ore sorting, which decides whether a 6-in. rock can be differentiated and disposed of before it goes through the plant," Wasmund explained.
