Gold Mine Closure and Decommissioning: 1 - 5 years. After a mine has ceased operations, possibly because the ore body is exhausted or the remaining deposit becomes unprofitable (uneconomic) to mine, work then focuses on its decommissioning, dismantling and rehabilitation of the land in which it was situated.

maximum of 30%, with 10% being typical. To illustrate this point, figures 2 and 3 show recovery and grade as a function of yield for a typical high grade gold ore sample tested at Gekko Systems Pty Ltd. As mass yield is increased the gold recovery increases. Batch units such as BCC's are limited to mass flow to concentrate
