CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.

It is important to note that, in many appli-cations, the downstream process that separates solvent from the solute(s) is usually more expen-sive than the extraction operation itself. A complete extraction process is illustrated in Figure 9.1. Figure 9.1: A schematic diagram of a complete liquid-liquid extraction process.
So, to extract the gold, the scientists need: 1. A bio-sorbent that adsorbs gold. 2. To remove gold from the e-waste 3. To use the bio-sorbent to adsorb the gold 4. To retrieve the gold from the bio-sorbent. For the first step, the leaves of Lagerstroemia speciosa, commonly known as "Pride Of India", are used.

The Hunter–Nash method uses material balances and a ternary phase diagram with phase separation to determine the number of equilibrium stages needed for liquid-liquid extraction (LLE). The system contains a solvent, carrier and solute. Select a feed composition from the drop-down menu. The solvent mass flow rate is given, and …
Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in …
Watch this two-part series of videos from LearnChemE that shows how to use the Hunter Nash method to find the number of equilibrium stages required for a liquid-liquid extraction process. Hunter Nash Method 1: Mixing and Operating Points (9:30) Hunter Nash Method 2: Number of Stages (6:30) Example. 1000 kg/hr of a feed containing 30 …
Take the follow 6 steps for help you design and build a high efficiency CIP or CIL gold processing plant to extract gold from the gold ore.
Gold ore beneficaiton and extraction equipement manufactured by Fote Company can process all types of gold ores like placer gold ores, rock gold ores, etc., and greatly improve the recovery …
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores …
The procedures to extract gold from ores in this plant is mainly composed of floatation, washing and conditioning, gold cyanidation leaching, two-stage washing and gold recovered by zinc.
In addition to the obvious and important cathodic reduction of the auro cyanide ion to metallic gold, it is important to review briefly the other cathodic processes that are …

Flowchart Tutorial (with Symbols, Guide and Examples) A flowchart is simply a graphical representation of steps. It shows steps in sequential order and is widely used in presenting the flow of algorithms, workflow or processes. Typically, a flowchart shows the steps as boxes of various kinds, and their order by connecting them with arrows.
