01/05/2015· Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard benchscale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanideconsuming ores. Such scaleup factors may not be appropriate for ores that deplete
Gold Processing Plant, Carbon In Leach (CIL) Plant. A Carbon In Leach Gold Recovery Plant. This plant processes 4 million tons of ore per year with an average gold content of ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for
01/01/2016· 4. Indicative Plant Design Criteria. Typical design criteria are given here for the unit operations associated with highsilver gold ore plants. The Merrill–Crowe criteria will be similar whether this style of plant is installed on a heap leach or stirredtank leach and is
The fundamentals and rules of thumb in scale up of laboratory testwork results, plant design and heap leach construction are discussed. The very important interrelationship of pH control, percolation and lixivant consumption is discussed in some detail giving enlightenment as to why many heap leaches give unexplained poor recoveries. 1.

Abstract: This paper represents a plant optimization (capacity improvement) study for a gold heap leach plant to obtain the product size of of 6 mm crushed ore at a capacity of 180 Mg/h. The former plant flowsheet was redesigned to obtain the target product size and capacity by modeling and simulation. The plant measurements and ore test work were carried out as the first part of the

gold plant will be that of the leaching and carboninpulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make up some 15% of total operating cost, whilst the capital costs associated with these areas is about 16% of the total. Although not largest (capital and operating costs associated with comminution
However, more complex or novel processes will require progressive stages of testwork, from laboratory to continuous pilot plants, to prove up and optimise the process ead of plant design. Grind size is usually the key process parameter in a leach plant, as grinding represents the highest energy input and cost element in the overall process
plant design may be "lessthanoptimum" because: Gold extraction efficiency is usually good enough even under less than optimum conditions. Economic payback is very good, even though capital costs, operating costs, and soluble losses may be higher than necessary. 7 OPPORTUNITIES Existing Plants – Lower Opex and Losses •Increase/decrease carbon concentration (g/L) •Increase/decrease

The very important interrelationship of pH control, percolation and lixivant consumption is discussed in some detail giving enlightenment as to why many heap leaches give unexplained poor recoveries. 1. Overview of Percolation Leaching
Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settlingout of solids

Precious Metal Heap Leach Design and Practice Daniel W. Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirtyseven different heap leach operations
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching the gold ore slurry simultaneously, CIL process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98%. It has become the first choice of modern gold mining and beneficiation plant design.
