The gold must be in a fine particulate form (from the grinding circuit). The feed slurry must have an 80% passing size of 75um to achieve suitable gold recovery (refer to cyclone and grinding modules). If the particles are too large they may not be totally leached during their residence time in the tanks and hence will report to tailings.

Project Report Of Quartz Manufacturing Plant In Chad. Crusher Dust — Redland Soils. Our Crusher Dust is mostly used as under slab preparation for concrete, or sometimes as a bedding for paving.It is made from recycled crushed concrete or rock sized 5mm & smaller, which makes it quite fine & easy to spread or screed.

During comminution there is a generation of abraded iron surfaces from grinding media and the broken particles can be deposited on gold surface changing gold particles characteristics and its behavior during recovery processes such as flotation and leaching. In this way, gold particles are smeared and its natural properties are affected.

With the rather small incremental recovery increase shown in Figure 6 (from 4 minutes to 8 minutes of grinding) it was decided that the optimum recovery …

studies. Those studies indicated that a P80 of 90 μm was the optimum grind size. At that time we recognized that finer grinding could result in higher gold recoveries, but the additional capital (i.e. larger mills) and power could not be justified to achieve the incremental increase in gold recovery. With the successful completion of the
