Modeling and optimization of Carbon in leach (CIL) circuit

Abstract. Carbon in leach (CIL) is an important step in gold processing that involves simultaneous adsorption and leaching. While the mechanism of leaching and The introduction of activated carbon to recover gold from cyanide leach solutions in the last quarter of the 20th century had a breakthrough impact on the economics of gold ore processing, as the world gold industry entered a period of unparalleled expansion following the deregulation of the gold price in the mid-1970s.Gold process modelling.

Factors influencing the rate of gold cyanide leaching and adsorption

In a CIP plant, leaching is complete before the first adsorption tank, and gold is then recovered from the leached pulp in a series of (typically) 4–10 dedicated carbon adsorption tanks. In a CIL plant, the carbon is added directly into the leach tanks, with the claimed advantage of lowering capital costs by eliminating the CIP adsorption tanks.The Copper Pressure Oxidation Plant is an Outotec proprietary technology for impure concentrate refining. The new process offers an effective way to dissolve concentrate, remove impurities, and Outotec copper concentrate pressure leaching

Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) A variety of modeling techniques can be utilized to forecast metal production at heap leaching operations. These approaches reflect a wide range of complexity, flexibility, time to implement, cost, and accuracy. For many operators, a spreadsheet-based modeling technique is attractive since the calculations are directly accessible, models can often be Heap Leach Production Modeling: a Spreadsheet-Based Technique

A trade-off between plant and soil carbon storage under Nature

Terrestrial ecosystems remove about 30 per cent of the carbon dioxide (CO2) emitted by human activities each year1, yet the persistence of this carbon sink depends partly on how plant biomass andCyanide-free mild chloride leaching was investigated. •. Gold could be recovered even at <520 mV vs. Ag/AgCl in carbon-in-chloride-leach mode. •. Copper was a stronger oxidant than iron in gold leaching. •. Gold was oxidized by in-situ dissolving impurities. •. Seawater contains enough chlorides to dissolve gold.Cyanide-free gold leaching in exceptionally mild chloride

Carbon-In-Leach Jacobi Group

The activated carbon used in the carbon-in-leach circuit preferentially adsorbs the gold over the native carbon and allows the gold to eventually be recovered for stripping. Jacobi offers a full range of carbon products to serve the gold recovery industry. This includes standard granular activated carbon grades (GoldSorb™ 4500 and The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500.

It concentrates gold from 2.5-3.5 g/t in ore to 10000 to 15000 g/t on carbon, thus playing an important role on the economics of a gold refinery. In this study, a dynamic model of CIL circuits has beendeveloped to study the transient nature of the system.The Hassai gold mine is an open pit mine located in the Red Sea Hills desert in north-eastern Sudan, approximately 50km from Khartoum.
