Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.
A sulfuric acid leaching line consists of: an acid storage and preparation yard (25% sulfuric acid solution); a leach reactor; a manganese sulfate tank; and a slime pit. Sulfuric acid leaching of manganese carbonate ore, manganese slags and ferromanganese concretions pro-duces a 23–25% manganese sulfate solution, from which
The concentrations of different impurities in the final leach solutions after leaching for 48 h are shown in Table 9. The analysis of manganese in the final leach solution indicates and confirms that manganese has been precipitated from the solutions as MnO 2. Some manganese dissolution was observed at low pH, where the extent of reaction ...
Answer (1 of 3): Leach lines are typically very shallow vs dry wells, which are much deeper. One answer stated they could be 45 feet deep. I've never seen one even close to that deep. they are typically only around 4–7 feet deep. it depends on the area. If the area ground water, is very deep - d...
A method and apparatus for precipitating manganese from acidic sulfate solutions, and more specifically from zinc leach solutions, without removing zinc. A zinc- and manganese-containing solution is treated with an SO2—O2 gas mixture at the appropriate pH and temperature, thereby causing manganese to precipitate as a trivalent and/or tetravalent manganese hydroxides and/or oxides that …

uranium processing - uranium processing - Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore ...
The process of leaching manganiferous ocean nodule ores with HCl whereby the manganese and other metals present, such as iron, zinc, cobalt, nickel, copper, and like are converted from oxides, silicates or other insoluble forms to water soluble chlorides, and are thereafter separated, purified, and the manganese recovered as MnO 2 by oxidation with chlorine to provide a material suitable for ...

The column-leaching tests, however, indicate that leaching of rhodonite is possible even though the solubilization reaction is slow. Leach solutions consistently containing 1.5 to 2.0 g/L Mn were still being obtained when the test was terminated. Leaching of Mn Ores. The ore column-leaching test results are given in table 4.

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;
The leaching process may employ one of a variety of chemicals such as dilute sulfuric acid, dilute aqueous cyanide, or other reagents. Methods for contacting ore and solution include agitating ground solids and solution (slurry) in open tanks, agitating slurry at a high temperature in a pressure vessel, or percolating solution through crushed ore that has been piled in a heap
2. Air agitated leaching tank, utilizes the aerodynamic action of compressed air to agitate the slurry. 3. Air-mechanical combined agitation leaching tank, a perfect combination of the two leaching tanks (1) and (2), with both effective mechanical and compressed air agitator. The fast dissolution of gold is the main advantage of this device.
