· Processing of refractory gold ores 1037 The oxidation tanks themselves are often configured in four stages with additional tanks employed in the first stage to accommodate the increased oxidation rates and aeration requirements in the initial phases of the reaction. Residence times in the tanks are often of the order of 3 to 4 days.

· Heap leaching has become a popular method of extracting gold, writes Nicolaas C. Steenkamp and Leon Louw. Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later.
efficiencies than heap leaching facilities, recovering from 85 to 98 percent of the gold contained in the ore. Generally, CIP or CIL methods are used for high grade ore. Oxide ores are typically beneficiated by grinding to 65 mesh and leaching with 0.05 percent sodium cyanide
· Heap leaching is used for low-grade oxides, while high-grade ore (with or without oxides) is better suited to CIP or CIL methods," says Bundo. Bundo explains that while heap leaching is not as costly as CIL or CIP, the recovery achieved is also not as efficient.

Direct leaching of gold ores such as heap leaching, carbon in pulp (CIP), carbon in leach (CIL) and resin in pulp (RIP) are summarized. This paper also dicloses in a detailed manner the research approach on the development of alternative leach reagents which could improve environmental concerns as compared to the use of cyanide.
· Operating Costs of Gold Processing Plant. A small gold mine flowsheet is shown below together with cost data which clearly shows the results that can be ''obtained when handling a low grade ore by a simple process. There are many commendable features in such a set up and no complicated machines or practices are embodied in this plan.

· CIP and CIL circuits generally have lower capital and operating costs for gold ore bodies than agitated tank leach circuits. Silver ore bodies show better economics with agitated tank leach-Merrill Crowe circuits. This is because the volume of carbon that would
calculated. Such a study, considering a differential cash flow analysis for CIP versus Heap Leaching, was reported by McLean, 1988. In this paper a 15% absolute recovery differential was assumed. The realised gold price and recovery values assigned are
When mines not surveyed are taken into account, it is likely that heap leaching produces 12% of the world''s gold. Heap leaching for silver is conducted using the same principles and operating practices as for gold, but heap leach operations produce only a small fraction of world silver production. INTRODUCTION.
