The table design minimizes turbulence in the slurry as it flows across the table. Low turbulence means a higher recovery of even the finest gold. We know of no gravity recovery system that beats our proven ability to capture 95% of the gold to 325 mesh (50 microns) or less. Proven applications: Hard rock mining; PCB and ewaste processing

FEECO hammer mills utilize a central rotating shaft, fitted with several "hammers" affixed to pivots on the shaft. As the shaft spins, the hammers are swung via rotational energy, causing them to collide with the material, breaking it up into smaller particles. Hammer mills are flexible, and can be used in a variety of applications.

A 20Mt/a mill will have a capital cost within 10,000 /t/h and 20,000 /t/h (Lane, Fleay, Reynolds, La Brooy, 2002). Typical operating costs for mills used in gold extraction are summarized in Table 3. The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV.

Hammer mills consist of a series of hammers suspended from a central shaft and enclosed within a rigid metal casing. Particle size reduction in a hammer mill occurs as a result of the impaction/attrition between the rapidly moving hammers and relatively slowmoving particles (Koch, 2002; Van der Poel et al., 2018). A screen fitted in the ...
