The Gold Heap Leach Cost Guide brings all the pertinent costs for gold heap leaching into one convenient reference. The guide provides estimators, engineers, investors and accounting professionals with cost estimating models for mining, heap construction and placing, gold recovery, and reclamation.
The Gold Heap Leach Cost Guide provides current costs for today’s mining methods and heap leach processing technologies across a wide range of production rates. It surveys the variety of operating conditions world-wide, along with their reserve base, and addresses methods in use to reduce costs and increase the rate of recovery for gold.
The guide provides costs for the most common methods of processing in use today including carbon adsorption and Merrill-Crowe zinc recovery methods and the ROM and CSA pre-leach options.
Several papers address special topics consisting of leach pad construction alternatives, re-contouring for reclamation, heap leach closure, equipment leasing, costs of cyanide consumption and agglomeration, cost indexes for adjusting costing estimates and more.
