The resultant uranium precipitate is then filtered or centrifuged, dried or calcined, and packaged into suitable drums for shipping. All processing plants maximize solution and reagent recycling to reduce cost and environmental effects. A typical conventional agitation leaching process is illustrated in Figure 4.9. The final yellowcake …

Agitation leaching is a process where the soil is slurried with the extraction fluid for a period of time. When equilibrium between the metal on the soils surface and the metal contained by the solution is approached, the solubilization of the metal in the soil is slowed, and the extraction is considered to be complete.

Gold Leaching done in round vats, constructed of wood, concrete, or iron and steel. If wood is used it is covered by a coating of paraffin paint, or by a mixture of asphaltum and coal-tar. Concrete and brick vats are not now advocated owing to their great cost and less convenient working, and wooden vats suffer more than iron and steel ones …

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 …

The results showed 83% Ni extraction after 4 h leaching, under optimized conditions i.e. temperature at 95 °C, acid concentration at 5 N and agitator speed at 1000 r/min. This study revealed that factorial experimental design can be implemented to identify effective parameters on the agitation leaching process of nickel laterite.

The next logical step we took was to explore the novel application of biochar and swine manure mixture to reduce nutrient leaching from soil and increase plant-available nutrients (Banik et al., 2021a,b). The study reported that using biochar and manure mixture significantly increased the organic matter, total carbon (C), and total N of the soil.

Pachuca tanks are used for a wide variety of leaching and mixing operations in the minerals industry. Previously, an equation was derived to predict the circulation in a Pachuca tank with full height draft tube risers. This analysis was subsequently verified with data from a large bore air-water flow loop used. However, the equation was based on …
