[QUOTE="Goldtalk Leonora, post: 583040, member: 5638"] Any gravity recovery is only ever going to give you 50-60% recovery. Finding the correct grinding fraction is all fine except most of that size gold will not be recoverable by gravity anyway. It is better to match the crushing/recovery circuit to the ore....but how many prospectors are sitting on several hundred thousands of tonnes of dirt? I can only speak for ourselves....we have a crushing and grinding circuit....then change between recovery units depending on the gold....then stockpile the sands as they still contain values for leaching at a later date...or onselling to companies looking for mill feed which is the more likely scenario in our case. This system keeps things simple....gives us a cash flow and allows us to pull small high grade pockets from around the area and bring it to one central point to process. I would love to have the money to just leach straight away...but gravity keeps things simple....running oxides only also keeps the mines dept happy! [/QUOTE]
