Target Resources - Milestone Gold Mine Project – Sierra Leona, Africa
Project Manager - Harold Young went into an old Diamond and gold mine in Sierra Leona Africa to rebuild, commission and startup. His job was to see if the equipment that was on the job site could be rebuilt or needed to be replaced. The equipment consisted of a 50 ton per hour DMS plant for diamond recovery - this plant could be rebuilt. The dredge equipment was worn out and needed to be replaced with a 10’ cutter head dredge. The new 10’ cutter head dredge arrived on the job site in July of 2008. It was commissioned in August of 2008 and put into service along with a new 200 ton per hour jig concentration plant. We replaced (2) D8N dozers and a 345 Cat excavator and rebuilt a D7N dozer and a 345 cat excavator. I bought 5 new Cat 35 ton hall packs and a new DMS diamond recovery plant with a new gold recovery plant were installed and put into operation and he also trained the Maintenance and Operation crews how to maintain and run the plant.
When Harold started work on this project they were recovering 180 carats of diamonds per month average and no gold. When I finished with the project they were recovering 4,000 + carats of diamonds per month and 200+ oz. of gold per month.

HPGR service:
EdRockMan IV LLC & HPGR Service Solutions Pty Ltd is a new company aiming to assist process plants with High Pressure Grinding Rolls to get the most out of their machine investment by achieving high availability, high efficiency, mineral processing.
The dynamics and variables of a process plant can be quite demanding on the installed equipment, so careful consideration needs to be given in order to gain the most from the installed power. A well-tuned HPGR will be able to cope with these dynamics and provide opportunities to increase efficiencies, not only in the HPGR plant, but also from the equipment upstream and downstream.
Whether you're looking for more uptime from your HPGR, reducing the load on downstream equipment, looking for maintenance improvements or need assistance with planning, supervision or the complete change out of a machine, we have a solution to meet your needs.
Through your available data, and analyzing problematic situations combined with previous experience, we can work with your existing team to tailor set points and make adjustments to improve and optimize your current processes.
