Hillgrove Header

Hillgrove have redeveloped a known Copper deposit at Kanmantoo in the Adelaide Hills. Originally mined in the late 1800’s, and then again in the 1970’s, Hillgrove reopened the mine and established a Mineral processing plant capable of processing about 2.5 Million tons a year of Copper Ore.

Due to the ongoing demands of running a mine site ammjohn have assisted Hillgrove with the placement of a resident mechanical engineer on site, from the start of the mine in November 2011 and ongoing.

We are based in the processing department and assist in all aspects of extracting the copper from the ore from the loading of the Run of Mine bin, crushing, screening, grinding, floatation, thickening, loading the concentrate into the trucks for shipment, tailings dam storage and water reclamation.
