Many old-timers and even more modern miners lost a remarkable amount of gold in their mining operations. Some tailing piles contain fortunes in lost gold values if identified and properly reworked with modern mining methods. Lode or hard rock tailings and mine dumps can be very productive sources of gold specimens, as many times good…
WhatsApp: +86 18221755073The centre-line method is a combination of the upstream and downstream designs. When raised, material is placed on both the tailings and the existing embankment so the embankment crest is raised vertically. In-pit tailings disposal makes use of worked out open pits. Backfilled tailings are stored underground in previously worked out voids.
