RE:RE:RE:RE:RE:RE:How come NFG won't do a trial mine?And only needed to determine recovery. Not required in a gold quartz setting. If a complicated recovery and refining required then this is needed.
Many ore types require a determination of % recovery and best method to achieve the best results so bulk processing required.
In many ore deposits, other minerals have to be separated as well and they can be either a positive or a negative. Ie. cost more or less than their recovered value.
