Insitu Copper Recovery Is a Rare Opportunity for Flore.

The PTF is a one to two year demonstration of insitu copper recovery. This stateoftheart method requires no open pit, no tunneling, no blasting, no waste dumps, and none of the large equipment typically associated with traditional mining activity. The first copper cathode was produced in April 2019.

– Climb mill with this 2/3's cut ratio. Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it out before the chip releases.

Face milling 1Face milling 2

Face milling

Face milling with a very high feed per tooth (up to 4 mm/tooth) is possible when using cutters that have small entering angles, or when using round insert cutters, due to their chipthinning effect. Although the depth of cut is limited to less than mm, the extreme feed makes it a highly productive milling method.
