Also in 1989, Peko Mines, then a division of North Broken Hill Peko Limited, also engaged Jameson to undertake test work in its Warrego concentrator near Tennant Creek in Australias Northern Territory. The objective was to determine the Jameson Cells performance in cleaning copper concentrate to improve its grade by removing gangue minerals, including pyrite, magnetite, hematite and quartz. Peko Mines personnel also tested a conventional flotation column for comparison. Following the test work, Peko Mines installed two full-scale, 1.4 m diameter Jameson Cells in the concentrator, each with three downcomers.
Peko Mines' decision was based on:
* metallurgical performance during pilot plant test work
* lower capital expenditure and installation costs
* shorter construction and installation times
* ease of operation and lower expected maintenance costs.
Peko Mines reported a payback on the investment in the Cells of two months.
