PT Newmont Nusa Tenggara plans to stockpile approximately 500Mt of copper ore for up to 20 years at the Batu Hijau mine on Sumbawa Island, Indonesia. Cu recovery from unoxidised ore is about 85%. It was not clear what the impact of oxidation would be on recovery after ore was stockpiled for 20 years. The company decided to undertake a field ...

A significant barrier to the development of a practical stockpile model is the large number of particles contained within the pile. Given that a size distribution, representing a typical coarse ore stockpile size distribution truncated at 10 mm, would contain approximately 220,000 particles per cubic meter, and a large ore pile in the minerals industry can contain more than …

stockpile approximately 500 Mt of copper ore, for up to 20 years. Much of the copper is present as the copper sulfide chalcopyrite. Construction of the stockpile commenced in late 2000 and as of early 2007 the pile contained regions more than 100 m high. Oxidation of chalcopyrite in stockpiled ore results in reduced copper recovery during ...

The measurements (data from site) are automatically stored in the data logger (data collector) of the Total Station instrument. The data is downloaded to a PC to calculate the volume and generating contour map by using Civil CAD software.

A typical coarse ore stockpile (Fig. 1) is fed from either a fixed or moving conveyor with primary crushed (minus ∼ 250 mm) rock to build up a pile above one or more fixed discharge feeders or draw points.These feeders discharge onto one or more belt conveyors that in turn each feed an autogenous grinding (AG) or semi autogenous grinding (SAG) mill.

The overall performance of RFID-based ore tracking through the stockpile is poor. Most RFID tags were reclaimed prior to their associated ore batch. This indicates that the tags, being smaller than even the fine ore particles, pass through the stockpile faster than the ore. It was also observed that the interval between tags varied from 1 to 9 s.
