Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low
wastewater treatment, so that a conscious selection, design and operation of the wastewater treatment process may be practised. Theory is considered essential for the understanding of the working principles of wastewater treatment. Practice is associated to the direct application of the concepts for conception, design and operation.
As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for …

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...
